The Quadra Project – Deep Water

By Ray Grigg

When we think about environmentalism, we tend not to consider the oceans because we don’t live on or in them, and they are just there as they have always been, defining the edge of the land that we occupy. Of course, oceans provide us with most of our fish, but in the popular understanding, they are mostly experienced as vast spaces of waves and wet that separate the faraway continents that we visit. So we tend to give much more importance to landscapes that we occupy. And because we live within the thin layer of air that girdles the globe, weather is also a concern to us. But we generally don’t consider that much of our climate and weather is determined by what happens in the oceans.

Satellites track the tiny silver fish hugely important to marine life

A new scientific endeavour has taken to the sky using high-tech drones and satellite images to understand better the annual spring herring spawn vital to salmon and wildlife on the West Coast. 

Between February and March each year, frigid ocean waters transform to a milky tropical-looking turquoise green when male herring release milt to fertilize the countless eggs deposited by females on eelgrass, kelp and seaweed fringing coastal shores.

Unpredictable and dramatic, the small silver fishes’ spawning event is large and best monitored from great heights, said Loïc Dallaire, a researcher with the SPECTRAL Remote Sensing Laboratory at the University of Victoria. 

“It’s one of the very few animal formations that we can see from space, excluding human developments and towns,” Dallaire said.

The Quadra Project: Welcome to 2024

Unless you’re brave enough to consider the reality of our global environmental situation, don’t read this. Confronting it is not a matter of being pessimistic or optimistic, but of being realistic—of assessing what we’re doing on our planet, what we want to avoid, what we want to accomplish, and what we can do both collectively and individually to have a more promising future. In one more year we will have reached a quarter of the way to 2100, and we are well on our way to creating conditions that we will either applaud or bemoan.

The Quadra Project: Dysbiosis

Dysbiosis is a new word for our vocabulary. It has been used before to describe a health condition created by an imbalance in the gut bacteria, which causes a wide range of gastrointestinal problems. Now dysbiosis is being used to describe a variety of our environmental problems.

It’s a timely word formed from two Greek roots. The prefix “dys” denotes difficulties, abnormalities, or anything that is uneasy, unfavourable or unfortunate. The suffix, “biosis”, denotes a state of living or a mode of life. Put the two together and we have a word that describes the malfunctioning of a biological system caused by some profound imbalance.

B.C. launches blueprint to fend off climate’s ‘one-two punch’ on the ocean

Canada’s National Observer, Local Journalism Initiative Reporter

B.C. has unveiled an action plan to tackle the two greatest climate threats to the ocean, coastal communities and marine ecosystems on the West Coast. 

Ocean acidification and hypoxia (OAH), or plummeting oxygen levels, that often occur in tandem with a snowball effect, are spiking due to human-caused greenhouse gas emissions. 

The plan’s goals include strengthening scientific collaboration and research and public awareness on these issues. Finding ways to adapt to or mitigate the negative impacts of OAH is also a priority. 

The province also wants a better understanding of how or if blue carbon — CO2 captured naturally from the atmosphere by marine plants and algae — could or should be used as a natural solution to buffer acidification and hypoxia.
