My Drive Across Canada: Part 1—Lake Superior

/ thealiennextdoor / 1 Comment

It was time to go back out west for me. So, I packed up my car Benny with my precious treasures—including all my plants—and drove west from Peterborough, Ontario (where I’d been living for a decade). My destination was Vancouver, BC, where my son and sister and good friends live.

I looked forward to the drive through the boreal forest of the Canadian Shield—spectacular country of mostly black spruce forest, rugged billion-year old rocks and ancient inland seas. Because I’m a limnologist and ecologist, I particularly looked forward to driving along the northern shores of Lake Superior. Distinguished by iconic terraced cobble shores, vast sand beaches, steep gnarly cliffs and brooding headlands, Lake Superior was certain to be a highlight of my trip. I anticipated experiencing this Great Lake with the giddy excitement of a child.

I got my first glimpses of this massive lake at Sault Saint Marie, a charming town on the southeastern shore of Lake Superior and the location of the lake’s outlet, St. Marys River. My first stop for a more immersive experience of the lake was Batchawana Bay, part of Pancake Bay Provincial Park, where I explored the mostly sand coast and shore forest. I’m told that the name Batchawana comes from the Ojibwe word Badjiwanung that means “water that bubbles up”, referring to the bubbling current at Sand Point.

Batchewana Bay is not only a main access point to several trails of the Lake Superior Water Trail; it also serves as a popular place for boaters and kayak paddlers to launch their craft for water adventure. The cold water and high wind fetch often make for treacherous boating. The Lake Superior Watershed Conservancy put up a sign at Batchewana Bay warning paddlers about dangerous and wily currents, including rip currents and channel currents and effects of offshore winds, accompanied by sudden surges.

From Batchawana Bay, I continued north along the lake’s eastern shore, past Chippewa Falls, formed on 2.7 billion year old pink granite bedrock, covered by a later basalt flow; here, the Harmony River tumbles some 6 metres before emptying into Lake Superior.

I found access points including Stone Beach, Alona Bay, Agawa Bay, and Katherine Bay, variously dominated by pebbled shores with rocky granite outcrops and finely sculpted sandstone—all overseen by windswept pine, cedar and spruce. This part of the lake lies in the Great Lakes-St. Lawrence Forest area, dominated by mixed forest of fir, spruce, cedar and paper birch.

Along the cobble shores of Alona Bay, I met a trio of rock hounds, looking for distinct Lake Superior agate, quite fetchy with its rich red, orange and yellow colours. I was told that the colours are caused by the oxidation of iron that leached from rocks. Fascinated by their varied colours and rounded shapes, I fell into a hypnotic meditation, picking up pebbles, rubbing them wet to reveal their bright colours and examining them close up.

On the pink granite in Alona Bay, I found some brilliant lichen, which I confirmed was Elegant Starburst Lichen (Rusavskia elegans formerly Xanthoria elagans)—documented by other lichenologists as common on Lake Superior’s granite shores. I also saw patches of Rock Disk Lichen (Lecidella stigmatea).

Agawa Bay and surrounding high points provide magnificent views of the Lake Superior shoreline and surrounding country. The high rising hills are easily one of the most rugged and beautiful in Ontario. The area is underlain mostly by over two billion year old granitic rocks of igneous origin that form part of a large batholitic mass formed in the Algoman period of Precambrian time.

.

Trail to Agawa Rock, Lake Superior, ON

.

It’s a short hike (0.8 km) through the woods on a trail that leads to the Agawa Rock Pictographs, an amazing collection of Aboriginal pictographs that sends one’s senses soaring with imagination. Beautiful representations of real and mythical animals fill the granite canvas;, one is Mishipeshu, the Great Lynx. This mythical creature is a water dwelling dragon-like animal that also resembles a lynx with horns and a back tail covered in scales. Mishipeshu is believed to cause rough and dangerous water conditions claiming numerous victims.

The trail it itself a highlight, takes you up a steep rock-hewn staircase, with steep cliff faces looming overhead, and along rocky pathways. The pictographs are viewed from a rock ledge below the 15-story high cliff that faces Lake Superior.

My second night stop was Wawa, on the edge of the boreal forest of the Canadian Shield, known for its giant ugly goose sculptures. The name Wawa comes from the Ojibwe word wewe for “wild goose.” The town, which resembles a modern-day version of an old pioneer town included the colourful Young’s General Store, where you could purchase anything from moccasins and fishing tackle to homemade fudge and ice cream.

.

From Wawa, I drove west along the most northerly shores of Lake Superior, stopping at access points including Schreiber Beach, Cavers and Rossport. I found this stretch of Lake Superior’s northern coast from Terrace Bay to Nipigon particularly enchanting. Here I found several access points off the road that drew me like Alice into wondrous boreal landscapes, offering windows to an ancient time before humans walked the earth.

Near Schreiber, I stopped on the road to explore deep pink smooth granite outcrops covered in foliose Cumberland Rock Shield Lichen (Xanthoparmelia cumberlandia) and cushions of fruticose Reindeer Lichen (Cladonia spp.) where shallow soil pockets had grown.

.

The Lake Superior shoreline at Rossport consists mostly of exposed primordial granite, worn smooth by wave action. The granite here is mostly pink feldspar, quartz, and black mica. According to E.G. Pye, this rock is called porphyritic granite, an igneous rock that crystalized from a natural melt, or magma.

.

Transition Zone & the Disjunct Plants of Lake Superior’s Northern Coastline

.

Though it lies in the boreal forest (typified by black spruce), the northern shoreline of Lake Superior in fact also supports species more characteristic of the Great Lakes-St. Lawrence Forest (e.g. white spruce, white cedar, red maple, paper birch). The northern shoreline of Lake Superior is therefore considered a transition zone between these two types of forest ecosystems.

.

Nestled in the rocky cracks and crevices of Lake Superior’s wild rocky shores, I discovered several cold-loving plants that normally grow in high alpine areas of the Arctic. Botanists refer to them as “Arctic-alpine disjunct plants,” separated from their usual arctic-alpine habitat and regarded as possible relicts of the last glaciation. Typically, such plants grow much farther north; but these plants have adapted to the unique cold micro-environment of Lake Superior’s northern shores. Examples include encrusted saxifrage (Saxifraga paniculata), black crowberry (Empetrum nigrum), bilberry (Vaccinium uliginosum), arctic fir clubmoss (Huperzia selago), elegant groundsel (Packera indecora), and the carnivorous English sundew (Drosera anglica).

I met old friends on the lake’s wild shores, lichens that made their homes on the water-smoothed rock surfaces and gnarly rock cliffs and boulders. Random patches of the crustose Yellow Map Lichen (Rhizocarpon geographicum), rosettes of the foliose Cumberland Rock Shield Lichen (Xanthoparmelia cumberlandia) and Tile Lichen (Lecidea sp.)—all lichens I’d encountered on my studied Catch Rock, a granite outcrop in the Catchacoma old-growth hemlock forest near Gooderham.

Circular patches of bright tangerine-orange Elegant Starburst Lichen (Rusavskia elegans formerly Xanthoria elegans) graced many of the rocky surfaces. I particularly noted them on the exposed granite slabs of Schreiber Beach and Rossport, often accompanied by Peppered Rock-Shield Lichen (Xanthoparmelia conspersa) and grey Cinder Lichen (Aspicillia cinerea).

William Purvis writes that R. elegans is a nitrophile (nitrogen lover) and is common at sites that are regularly fertilized by birds. In other words, they like bird poop. Inuit hunters knew that orange lichen meant small mammals like marmots probably lived nearby (the poop connection again). The orange colour comes from the carotenoid pigment, which acts like sunscreen to protect the lichen from UV radiation. This was the lichen that made it into space in 2005, exposed to the extremes of space (e.g. temperature, radiation and vacuum) for 1.5 years. Most of the samples continued to photosynthesize when they returned to Earth.

Lake History

Lake Superior was formed 10,000 years ago when glacial melt-water filled a billion-year-old volcanic basin. The lake is the size of Austria, covering an area of about 82,100 km3 and making it the largest lake in the world by surface area. Lake Superior holds 10% of the Earth’s surface freshwater—enough to fill the other Great Lakes plus three more Lake Eries, making it the third largest lake in the world by volume. The Ojibwe call the lake gichi-gami (great sea), which so aptly describes this inland sea.

For a comprehensive summary of Lake Superior’s geologic history and rock formations see E.G. Pye’s 1969 guidebook “Geology and Scenery: North Shore of Lake Superior.”

.

Lake Characteristics

Lake Superior is considered an oligotrophic lake of low productivity, characterized by cold, deep, nutrient-poor nutrients (particularly phosphorus and nitrogen). Its mean depth is 147 meters with a maximum depth of 406 meters. Fed by 200 rivers, Lake Superior holds 12,100 km3 of freshwater—enough to cover the entire North and South American continents with 30 cm of water. The lake’s volume is sufficiently large that it takes almost two centuries for a drop of water to circulate the lake before leaving through St. Marys River—its only natural outflow at Sault Ste. Marie—which flows into Lake Huron. Lake Superior also experiences seasonal circulation; the lake stratifies into two major temperature layers in summer and winter and undergoes mixing (turnover) twice in spring and fall, making it a dimictic lake.

.

Because of lack of plankton and turbidity from silt (due to cold waters low in nutrients), the lake is super clear with Secchi disk depths of 20-23 meters observed. Samuel Eddy at the University of Minnesota provided a summary of zooplankton and phytoplankton in the lake.

.

Macrophytes appeared nonexistent on the wave-washed shallows, though some boulders were covered in periphyton (e.g. attached algae, mostly diatoms). I also noticed some filamentous algae on the shore rocks near Rossport, likely Cladophora and Spirogyra, known to occur in the sheltered waters of the lake.

Lake Fetch & Seiches

.

Because of its size, Lake Superior provides long distances for wind to push water from one end to the other; these distances, called fetches, can exceed 500 km on Lake Superior. As a result, the lake experiences ‘tides’ called seiches—essentially oscillations in water level caused by strong winds and changes in atmospheric pressure. This causes a sloshing effect across the lake (of about a metre), much like a cup of coffee as it’s being carried, and exposes shorelines to dramatic fluctuations in shoreline levels with large waves, which can be as high as 6 m during storms.

.

Lake Geology

.

The rocks of the lake’s northern shore date back to the early history of the earth, during the Precambrian Era (4.5 billion to 540 million years ago) when magma forcing its way to the surface created the intrusive granites of the Canadian Shield. With a watershed rich in minerals such as copper, iron, silver, gold and nickel, the lake lies in long-extinct Mesoproterozoic rift valley (Midcontinent Rift). Over time eroding mountains deposited layers of sediments that compacted to become limestone, dolomite, taconite and shale. As magma injected between layers of sedimentary rock, forming diabase sills, flat-topped mesa formed (particularly in the Thunder Bay area), where amethyst formed in some cavities of the rift. Lava eruptions also formed black basalt, near Michipichoten Island.

.

During the Wisconsin glaciation 10,000 years ago, ice as high as 2 km covered the region; the ice sheet advance and retreat left gravel, sand, clay and boulder deposits as glacial meltwater gathered in the Superior basin

Although the lake currently freezes over completely every two decades, scientists speculate that by 2040 Lake Superior may remain ice-free due to climate change. Warmer temperatures may also lead to more snow along the shores of the lake.

My Short Story “The Polywater Equation” (Die Polywasser-Gleichung) in “Tales of Science II” Anthology

/ thealiennextdoor / Leave a comment

A few weeks ago, I looked into my mail box and found my contributor’s copy of “Tales of Science II” Anthology (edited by Marianne Labisch & Kiran Ramakrishnan) with my short story Die Polywasser-Gleichung (“The Polywater Equation”) inside. Beaming, I did a little dance because the anthology was marvelous looking! And it was all in German! (My mother is German, so I could actually read it; bonus!).

This science-fiction anthology, for which I was invited to contribute, collected seventeen short stories, all based on sound science. Here’s how the book jacket blurb (translated from German) describes the anthology:

.

It’s all just fiction. Someone made it up; it has nothing to do with reality, right? Well, in this anthology, there’s at least a grain of truth in all the stories, because scientific sponsors collaborated with authors. Here, they looked into the future based on current research What does such an experiment look like? See for yourself what the authors and scientific sponsors have come up with: about finding a way to communicate with out descendants, finding the ideal partner, conveying human emotions to an AI, strange water phenomena [that’s my story], unexpected research findings, lonely bots, and much more. The occasion for this experiment is the 20th anniversary of the microsystems technology cluster microTEC Südwest e. V.

.

In our initial correspondence, editor Marianne Labisch mentioned that they were “looking for short stories by scientists based on their research but ‘spun on’ to create a science fiction story;” she knew I was a limnologist and was hoping I would contribute something about water. I was glad to oblige her, having some ideas whirling in my head already. That is how “The Polywater Equation” (Die Polywasser-Gleichung) was born.

I’d been thinking of writing something that drew on my earlier research on patterns of colonization by periphyton (attached algae, mostly diatoms) in streams using concepts of fluid mechanics. Elements that worked themselves into the story and the main character, herself a limnologist, reflected some aspects of my own conflicts as a scientist interpreting algal and water data (you have to read the story to figure that out).

My Work with Periphyton

As I mentioned, the short story drew on my scientific work, which you can read about in the scientific journal Hydrobiologia. I was studying the community structure of periphyton (attached algae) that settled on surfaces in freshwater streams. My study involved placing glass slides in various locations in my control and experimental streams and in various orientations (parallel or facing the current), exposing them to colonizing algae. What I didn’t expect to see was that the community colonized the slides in a non-random way. What resulted was a scientific paper entitled “the effect of current on the distribution of diatoms settling on submerged glass slides.”

.

For more details of my work with periphyton, you can go to my article called Championing Change. How all this connects to the concept of polywater is something you need to read in the story itself.

.

The Phenomenon of Polywater

The phenomenon started well before the 1960s, with a 19th century theory by Lord Kelvin (for a detailed account see The Rise and Fall of Polywater in Distillations Magazine). Kelvin had found that individual water droplets evaporated faster than water in a bowl. He also noticed that water in a glass tube evaporated even more slowly. This suggested to Kelvin that the curvature of the water’s surface affected how quickly it evaporated.

.

.

In the 1960s, Nikolai Fedyakin picked up on Lord Kelvin’s work at the Kostroma Technological Institute and through careful experimentation, concluded that the liquid at the bottom of the glass tube was denser than ordinary water and published his findings. Boris Deryagin, director of the Institute of Physical Chemistry in Moscow, was intrigued and his team confirmed that the substance at the bottom of the glass tube was denser and thicker than ordinary water and had additional anomalous properties. This phase of water had a thick, gel-like consistency; it also had a higher stability, like a polymer, over bulk water. It demonstrated a lower freezing point, a higher boiling point, and much higher density and viscosity than ordinary water. It expanded more than ordinary water when heated and bent light differently. Deryagin became convinced that this “modified water” was the most thermodynamically stable form of water and that any water that came into contact with it would become modified as well. In 1966, Deryagin shared his work in a paper entitled “Effects of Lyophile Surfaces on the Properties of Boundary Liquid Films.” British scientist Brian Pethica confirmed Deryagin’s findings with his own experiments—calling the odd liquid “anomalous water”—and published in Nature. In 1969, Ellis Lippincott and colleagues published their work using spectroscopic evidence of this anomalous water, showing that it was arranged in a honeycomb-shaped network, making a polymer of water—and dubbed it “polywater.” Scientists proposed that instead of the weak Van der Waals forces that normally draw water molecules together, the molecules of ‘polywater’ were locked in place by stronger bonds, catalyzed somehow by the nature of the surface they were adjacent to.

.

Molecular structure of polywater

.

This sparked both excitement and fear in the scientific community, press and the public. Industrialists soon came up with ways to exploit this strange state of water such as an industrial lubricant or a way to desalinate seawater. Scientists further argued for the natural existence of ‘polywater’ in small quantities by suggesting that this form of water was responsible for the ability of winter wheat seeds to survive in frozen ground and how animals can lower their body temperature below zero degrees Celsius without freezing.

When one scientist discounted the phenomenon and blamed it on contamination by the experimenters’ own sweat, the significance of the results was abandoned in the Kuddelmuddel of scientific embarrassment. By 1973 ‘polywater’ was considered a joke and an example of ‘pathological science.’ This, despite earlier work by Henniker and Szent-Györgyi, which showed that water organized itself close to surfaces such as cell membranes. Forty years later Gerald Pollack at the University of Washington identified a fourth phase of water, an interfacial water zone that was more stable, more viscous and more ordered, and, according to biochemist Martin Chaplin of South Bank University, also hydrophobic, stiffer, more slippery and thermally more stable. How was this not polywater?

.

The Polywater Equation

In my story, which takes place in Berlin, 2045, retired limnologist Professor Engel grapples with a new catastrophic water phenomenon that looks suspiciously like the original 1960s polywater incident:

The first known case of polywater occurred on June 19, 2044 in Newark, United States. Housewife Doris Buchanan charged into the local Water Department office on Broad Street with a complaint that her faucet had clogged up with some kind of pollutant. She claimed that the faucet just coughed up a blob of gel that dangled like clear snot out of the spout and refused to drop. Where was her water? she demanded. She’d paid her bill. But when she showed them her small gel sample, there was only plain liquid water in her sample jar. They sent her home and logged the incident as a prank. But then over fifty turbines of the combined Niagara power plants in New York and Ontario ground to a halt as everything went to gel; a third of the state and province went dark. That was soon followed by a near disaster at the Pickering Nuclear Generating Station in Ajax, Ontario when the cooling water inside a reactor vessel gummed up, and the fuel rods—immersed in gel instead of cooling water—came dangerously close to overheating, with potentially catastrophic results. Luckily, the gel state didn’t last and all went back to normal again.

If you read German, you can pick up a copy of the anthology in Dussmann das KulturKaufhaus or Thalia, both located in Berlin but also available through their online outlets. You’ll have to wait to read the English version; like polywater, it’s not out yet.

Confessions of a Teenage Eco-Warrior

/ thealiennextdoor / Leave a comment

When I was little, I wanted to be a storyteller, a cartoonist specifically. I was reading graphic novels before I could read. That didn’t stop me from understanding what was going on. Being a virtual learner and an artist, I understood context: expressions, body language…

Nina, age three, pretending to read (photo by Martha Munteanu)

.

.

I wrote and drew wild adventure thriller detective stories and stories about exploring other planets. While my first love was telling stories, I was called by the needs of the environment. This percolated through me as I grew up and wouldn’t let go. When I could read and write, I still read graphic novels; I wrote and illustrated short stories about the environment, dystopian tales that focussed on how we were destroying our planet.

.

At school, I loitered in the hallways, pasting subversive posters on the walls. They were a call to action: Restrain … Reuse … Repurpose … Recycle … Remain true to the environment. I wrote in the school paper. I quoted global statistics, mentioned global warming (yes, people knew about it back in the ‘60s and ‘70s), and submitted cheesy emotional drawings of pollution and toxic waste.

I was a teenage eco-warrior.

By the time I was ready to go to university (I’d been accepted early into the fine arts program at Concordia University in Montreal), I switched my major on registration day. Like a horse bolting from a fire, I charged out of the arts and into the sciences. I’d heard environment’s call for help and had notions of becoming an environmental lawyer. I kept a few arts courses as electives but focused on a biology degree in the environmental sciences. I understood that the tools I needed to wield as an eco-warrior in law were rooted in science.

.

.

I learned something about ecology, botany, animal, plant, and cell physiology, genetics and biochemistry, and limnology (the study of water systems). The sciences fascinated me and I became entranced in the study of how the natural world worked. I was particularly attracted by lichens, plant-like organisms called cryptogams that grow like miniature forests on substrates—trees, fence posts, rock, cement. My attraction was partly because these often overlooked organisms were actually more of a symbiotic community or mini-ecosystem: an intriguing community of fungi, algae, cyanobacteria, bacteria and yeast growing together. I felt that on some level, lichen had much to teach us on lifestyle and approach to living on this planet. They’d been around for millennia, a lot longer than we’ve been.

Having long abandoned law (I convinced myself that I wasn’t cut out for it; maybe I was but that’s another universe), I decided to pursue lichen ecology for my masters degree. But fate had another path in mind for me. The botany professor who I wished to study under was retiring and no one was taking her place. She referred me to the limnology professor and he got me interested in another microscopic community: periphyton (the algae and associated organisms that colonize plants, rock and cement in water).

I published some papers, moved out west and eventually got married and raised a beautiful son. My limnological expertise led me to a position at the local university and as a scientist with several environmental consulting firms, where I consulted with clients, did field research, wrote reports, and published and presented papers at conferences.

.

I’d come somewhat full circle to be an eco-warrior, pursuing environmental problems (and corporate mischief) through biology rather than law. I designed and conducted environmental impact assessments and recommended mitigation, restoration, and remediation procedures to various clients from lakefront communities and city planners to mining companies dealing with leaky tailings ponds and pulp mills discharging effluent into the ocean.

.

Various reports, scientific papers and articles I’ve written or been interviewed for

.

It worked for me. I consulted for twenty-some years. It was for the most part both satisfying and encouraging. I felt as though I was making a difference: mostly through educating my clients. But that became less and less the case as the consulting firms I worked for, and the corporations they worked for, seemed to have less and less integrity. They also seemed to care less about the environment and more about profit.

So, just as I’d done on the day of registration at university, I bolted like a horse in a fire and quit my job as a consultant. I never returned to consulting.

My sights went back to storytelling, journalism, and reporting/interviews. Mostly eco-fiction. Creating narratives that would hopefully move people, nudge them to act for the environment. Change their worldview somewhat into eco-friendly territory. Make them care. I’m still an eco-warrior, but my pen and my storytelling is my tool.

The word is a powerful tool. And the stories that carry them are vehicles of change.

Ironic Tragedy of Forever Chemicals & Growing Infertility: Are We Solving Our Own Population Explosion Through Toxicity?

In the passage below of my eco-fiction dystopian novel A Diary in the Age of Water, the year is 2065 and the diarist Lynna (a limnologist at the University of Toronto) reflects on the steeply growing infertility in humans and our tenuous future. Lynna draws on the factual study published close to fifty years earlier (in 2017) by Hagai Levine and others at the Hebrew University of Jerusalem, who found that sperm counts among western men had reduced close to 60% in four decades:

Back in ’49, Daniel and I had several discussions about the environmental triggers and epigenetic mechanisms of infertility in humans. Daniel went on about how it was all about the men. While women showed signs of increased infertility, men’s rate of infertility was more than double that of the women, he said. Taking an inappropriately gleeful tone, Daniel cited the classic 2017 paper by the Hebrew University of Jerusalem, the one that started it all. Their findings were startling: men’s sperm count in North America, Europe, Australia, and New Zealand had diminished by sixty percent in forty years, between 1973 and 2011. The scientists predicted that by 2060, virtually all men in these parts of the world would have little to no reproductive capacity.

It’s 2065 and they’re right. Only it’s worse. Before the twenties, only the developed countries seemed to be affected, but then sperm counts started to plummet in South American countries, like Argentina and Brazil, where GMO, pesticides, and solvent manufacturing were exploding.

You get out what you put into the ground. India and Asia—where endocrine-disruptive chemicals are finding their way into the water—are reporting very low sperm counts in their men as well as higher incidents of intersex humans.

You get out what you put into the water. We are over two thirds water, after all. I find it a little ironic that we’ve inadvertently produced a non-discriminatory way to control the problem of humanity’s overpopulation. Infertility. And that infertility results from defiling the environment we live in.

But now climate change is shouldering its way in. Climate change is shutting us down.

Is this the first sign of our impending extinction?

–excerpt from “A Diary in the Age of Water”

That environmental perturbations impact our ability to reproduce has been proven. In their 2017 article, Levine et al. write that:

“Sperm count and other semen parameters have been plausibly associated with multiple environmental influences, including endocrine disrupting chemicals (Bloom et al., 2015; Gore et al., 2015), pesticides (Chiu et al., 2016), heat (Zhang et al., 2015) and lifestyle factors, including diet (Afeiche et al., 2013; Jensen et al., 2013), stress (Gollenberg et al., 2010; Nordkap et al., 2016), smoking (Sharma et al., 2016) and BMI (Sermondade et al., 2013; Eisenberg et al., 2014a). Therefore, sperm count may sensitively reflect the impacts of the modern environment on male health throughout the life course (Nordkap et al., 2012).”

Thanks to chemical companies such as DuPont and others, forever chemicals are currently in rain water globally, and in many places in unhealthy concentrations. These endocrine-disrupting and cancer-causing chemicals often end up in drinking water and include PCBs, phthalates, PFAS, BPAs (used in pesticides, children’s products, industrial solvents and lubricants, food storage, electronics, personal care products and cookware).

If you observe a terrible irony in this short list, also know that the chemical companies, such as DuPont, have known about the dangers posed by these products for decades and decided to keep it a secret.

My books “Water Is… The Meaning of Water” and “A Diary in the Age of Water” are selling at Banyen Books in Kitsilano, Vancouver. While “A Diary in the Age of Water” is on Banyen’s virtual shelf for order, “Water Is…” sits on a shelf in the Water: Life-force & Resource / Ecology section.

“Water Is…” sits on the ‘water as life-force & resource’ shelf at Banyen Books, Vancouver (photo by Nina Munteanu)

Banyen Books is located in Kitsilano on the south side of W 4th Avenue on the corner of Dunbar under a grove of healthy oak trees. Across the store is Aphrodite’s Organic Pies, itself a destination for awesome pies. Banyen Books is a beautiful store. It is spacious and surrounded with the warmth of wood and plants. Its wonderful atmosphere invites you to browse the shelves and sit on the comfortable chairs to read. Banyen Books has become a destination for me whenever I’m in Vancouver.

Since opening in 1970 Banyen Books has become Canada’s most comprehensive metaphysical bookstore, offering a broad spectrum of resources from humanity’s spiritual, healing, and earth wisdom traditions. Here is how they put it:

Banyen is an oasis, a crossroads, a meeting place… for East and West, the “old ways” and current discoveries and syntheses. Our beat is the “Perennial Philosophy” as well as our evolving learning edges and best practices in a wide variety of fields, from acupuncture to Zen, from childbirth and business to the Hermetic Mysteries, from the compost pile to the celestial spheres. We’re “in the philosophy business,” on “a street in the philosophy district” (as an old cartoon wagged). We welcome and celebrate the love of wisdom, be it in art, science, lifecraft, healing, visioning, religion, psychology, eco-design, gardening… Our service is to offer life-giving nourishment for the body (resilient, vital), the mind (trained, open), and the soul (resonant, connected, in-formed). Think of us as your open source bookstore for the “University of Life”.

Whenever I’m in Vancouver to visit family and friends, I make at least one stop at Banyen Books and often come out with an armful of books. On my most recent stop, I purchased a book on plant intelligence and several beautiful journals (I use a journal for each book project I work on).

H2O Publishes my Illustration of the Diatom Forest

/ thealiennextdoor / 1 Comment
My original Diatom Forest illustration in my article “Diatom Spring” in The Meaning of Water

This past spring, Dutch scientist Herman van Dam (Consultancy for Water and Nature) approached me for permission to use my illustration of the diatom forest in a paper he and co-authors were preparing for the Dutch journal H2O. He explained that they wanted to help familiarize water managers who read the journal with the underwater biodiversity for which my illustration would be helpful.

The Illustration

He’d seen my illustration in my article “A Diatom Spring” in The Meaning of Water. Below is a summary of my article about the diatom forest:

Attachment and colonization starts with a ‘clean’ unpopulated surface (usually scoured by turbulence in a storm or some other event or a new surface tumbled into the water). Several stages of succession take place, starting with early colonizers. The adnate Cocconeis placentula, whose frustules attach directly to the substrate, is an example of an early colonizer. When they attach to a substrate they form a biofilm (think moss in a terrestrial forest). Adnate species are eventually overgrown by taxa that produce a mucilaginous pad (e.g. Synedra) or stalk (e.g. Gomphonema). The understory layer is typically occupied by diatoms such as Fragilaria vaucheriae and Synedra radians that attach to the surface at one end (apical) of their rod-shaped frustules using a mucilaginous pad to form “rosettes” that resemble spiky understory shrubs. This allows them to protrude above the adnate taxa and take advantage of more light.

The diatoms Cymbella and Gomphonema produce long stalks that attach directly to the surface, allowing them to form a swaying canopy over the lower tier of cells of Fragilaria vaucheriae, Synedra radians and early colonizer Cocconeis placentula whose frustules attach directly to the substrate (think overstory and understory of a terrestrial forest or a marine kelp forest).

The Diatom Forest Structure

Just like trees, the canopy-forming stalked diatoms effectively compete for available light and nutrients in the water with their vertical reach. They provide the ‘overstory’ of the diatom forest’s vertical stratification. These tree-like diatoms also provide an additional surface for other diatoms to colonize (e.g. tiny epiphytic Achnanthes settle on the long stalks of Cymbella, just as lichen does on a tree trunk).

SEM of three-week colony of Cymbella affinis (larger diatoms on left) and Gomphonema olivaceum attached via stalks (image from Roemer et al., 1984)

The stalked diatom forest acts like a net, trapping drifting-in euplankton, such as Pediastrum sp. andFragilaria spp., which then decide to stay and settle in with the periphyton community. The mucilage captures and binds detrital particles in both lower and upper stories of the diatom forest; these, in turn, provide nutrients for the diatom forest and additional surfaces for colonization. In their work with periphyton communities, Roemer et al. (1984) found several diatoms (e.g. Diatoma vulgare, Fragilaria spp. Stephanodiscus minutula) entangled in the complex network of cells, stalks, and detritus of the diatom forest’s upper story. They also found rosettes of Synedra radians—like jungle orchids—attached to large clumps of sediment caught by the net of mucilage.

Eventually, ‘overgrowth’ occurs as the periphyton colony matures and grows ‘top-heavy’ with all this networking. The upper story of the community simply sloughs off—usually triggered by turbulence in a river from rains, storms, or dam release. This is similar to a forest fire in the Boreal forest, which creates space and light for new colonization and growth. The dislodged periphyton ride the turbulent flow, temporarily becoming plankton, and those that survive the crashing waters provide “seed” to colonize substrates downstream. Others may get damaged and form the ‘dish soap’ like suds or foam you often see in turbulent water. The proteins, lignins and lipids of the diatoms (and other associated algae) act as surfactants or foaming agents that trap air and form bubbles that stick to each other through surface tension.

The Paper

The paper was published June 13, 2024, in H2O, written by Jako van der Wal, Joep de Koning and Herman van Dam, and entitled “Snel inzicht in de ecologische waterkwaliteit met diatomeeën” (Quick insight into ecological water quality with diatoms). This paper was right up my alley! As a diatom specialist and limnologist who studied them in relation to environmental conditions and perturbations, I was intrigued by the paper and gained some additional insight on diatom ecology.

Van der Wal et al. cited recent advances in DNA-based identification methods that provide fast and cheap diatom identification over the traditional method of using an optical compound microscope to observe morphological characteristics such as size, shape and ornamentations of the silicified cell wall. I can attest that this is a labour-intensive process in which I spent many hours and days hunched over a microscope during my masters research at Concordia University. This efficient DNA-identification has seen a resurgence of using diatoms as a valuable tool for water quality managers, with applications providing insight into both current and historical water conditions. The authors argue that benthic diatoms or periphyton (living on substrates such as plants, rock, sand and artificial surfaces) have been since the 1980s used as indicators of saproby, trophy, acid and salt character in, among other things, ditches and canals. For every type of water and water quality, there are diatoms that have their habitat there, write the authors. They argue that, unlike phytoplankton, fish and macrofauna, periphyton attach to a surface and hardly move; this means that effects of water quality can be demonstrated locally. Because many diatom species tolerances and intolerances are known and they reproduce quickly (over days), diatoms respond quickly to changes in the environment—much faster (often within weeks) than other ecological indicators.

Scientists and water technicians can use diatom species composition to measure perturbations by organic material, low oxygen content, eutrophication, and toxicity. Given that diatoms colonize and develop quickly, this includes unstable and damaged habitats where other indicators cannot develop, such as shipping traffic, waves or where cleaning or dredging is carried out regularly. Historical insight can be provided by diatoms, given that their silica frustules are naturally preserved in sediment.

My Own Work with Turbulence

Periphyton biofilm (of mostly diatoms) on microscope slides left in a stream

During my masters research in several streams in the Eastern Townships, I examined how diatoms colonized artificial substrates; how they formed productive biofilms that sustained an entire periphyton community of attached aquatic life and discovered that their pattern of colonization related to current speed and direction. I submerged glass slides (the kind people use to look at critters under the microscope) in a device in the stream and oriented them parallel or perpendicular to the current.

There are two ways an algal community grows in a new area: (1) by initial colonization and settling; and (2) by reproduction and growth. I studied both by collecting slides exposed for differing lengths of time (collecting young and mature communities) in different seasons.

I discovered that the diatoms colonized these surfaces in weird ways based on micro-turbulence. Early colonizers, like Achnanthes and adnate Cocconeis preferred to settle on the edges of the slides, where the chaos of turbulence ruled over the sheer of laminar flow. They colonized by directly appressing to the substrate, making them the first photosynthetic taxa to establish a biofilm on a clean substrate. Vadeboncoeur and Katona (2022) write that “in waved-washed surfaces, these taxa may be the only algae that persist.” I postulated that the drift velocity was reduced on the slide’s edge, where turbulence was greatest, giving drifting algae a greater chance to collide and settle on the slide over the more shear laminar flow along the slide’s central face.

Once settled, the community was more likely to grow with turbulence. Greater turbulence decreases the diffusion gradient of materials around algal cells, with a higher rate of nutrient uptake and respiration. Turbulence provides greater opportunity to an existing colony by increasing “chaotic” flow, potential collision and exchange. Turbulence is a kind of “stable chaos” that enhances vigor, robustness and communication.

Using Diatoms in Water Quality Assessments

In their paper Van der Wal et al. argued that in environmental assessment the DNA-identification is just one step in a process that looks a population structure and health. Diatoms are already used in 21 of the 27 EU countries as part of a Water Framework Directive (WFD) quality index for flowing waters and in nine EU countries for standing water. Example conditions and associated perturbations where diatoms are a particularly useful indicator include: salinity, acidity, oxygen saturation, organic load (saproby), nutrient richness (trophy), temperature, and toxicity.

Diatom Growth Forms & Deformities

Van der Wal et al. argued that in addition to the different species compositions and the related ecological indices, growth forms and deformations of diatoms are useful indicators of water quality, particularly in relation to specific toxins.

My illustration adapted for the van der Wal et al. paper in H2O

Growth forms of diatoms can be described as attached, short-stalked, long-stalked, mobile and living in mucous tubes (Figure 3, van der Wal et al., 2024). Each growth form has advantages and disadvantages. For example, short-stalked diatoms are more difficult to graze and long-stalked diatoms come into contact with more water, from which they can then absorb substances. Long-stalked diatoms can also absorb more light if there is a lot of competition. Mobile diatoms can adapt to changing conditions by, for example, migrating from surface to subsurface and vice versa. Diatoms in slime tubes are more difficult to prey on and respond more slowly to environmental changes.

According to Van der Wal et al., scientistis (Rimet & Bouchez) noted that long-stalked diatoms declined in waterbodies subjected to various pesticides. Falasco et al. observed diatom deformities when exposed to various toxic substances. Heavy metals were observed to cause deformities in Navicula. Nitrogen toxicity was also implicated in diatom deformities.

My Journey with Water: Nina Munteanu Talks to the Toronto Probus Group

/ thealiennextdoor / Leave a comment
People reading “Water Is…” in Vancouver and Toronto

Margaret McCaffery, chair of the PROBUS Toronto Speakers Committee invited me some time ago to speak to their club in June of 2024 on my experience with water: as scientist, mother, and environmentalist. The audience was mostly retired professional and business people with enquiring minds. I gave my Powerpoint talk in the Holy Rosary Parish Hall on St. Clair West and then enjoyed a vigorous session of challenging and interesting questions to which I responded with equal vigour.

Here is the blurb for the presentation:

Canadian limnologist Nina Munteanu explores the many dimensions of water through her journey with water as mother, educator, and scientist. She describes an emotional connection with nature that compels us to take care of our environment with love versus a sense of duty. 

Nina’s talk draws on her book Water Is… The Meaning of Water, part history, part science and part philosophy and spirituality. The book examines water’s many anomalous properties and what these meant to us. In sharing her personal journey with this mysterious elixir, Nina explores water’s many ‘identities’ and, ultimately, our own. Water Is… was Margaret Atwood’s first choice in the 2016 New York Times ‘Year in Reading.’ Water is… will be available for sale at the talk.

I started with my story as a child, growing up in the Eastern Townships of Canada
I defined “limnology” and talked about my career as a limnologist and environmental consultant
I discussed some of water’s anomalous properties, all life-giving
I brought in some interesting things about water…
I tied my journey with water to family and friends and my watershed
I ended my talk with a discussion of the Watermark Project to catalogue significant stories to water bodies all over the world

I also brought my latest eco-clifi novel A Diary in the Age of Water for sale. It interested quite a few people and generated several wonderful discussions.

When Water Speaks: quotes from A Diary in the Age of Water

/ thealiennextdoor / Leave a comment

“The truth isn’t about telling; no one just tells you the truth. It needs to be coaxed, even tricked, out. The truth is carefully hoarded—like water—and only flows among privileged acolytes who have proven themselves.”

Lynna Dresden

“Those of us who are captivated by fear, who despair in a dead zone—we need to consider new ways to tell familiar stories, to envision different endings. A book like this can change the way that you see the world at this moment, can allow formulae to take root in fiction and grow into a different kind of solution.”
