Marine heatwaves a threat to B.C.’s shellfish industry says expert

Editor’s note: The shellfish industry is one of Cortes Island’s principle employers.

This summer was hot, not only for us, but also for the life in our oceans as marine heatwaves swamped B.C’s coastal waters. According to researchers, sea temperatures off northeastern Vancouver Island reached 21 degrees Celsius in July, boiling kelp alive.

In the first week of August the average global sea surface temperature reached a record-breaking 30 degrees Celsius.

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.

Unchecked climate change puts Canada’s West Coast in hot water

Canada’s National Observer, Local Journalism Initiative Reporter

Last year was the hottest on record for the ocean, an upward trend only expected to continue as it wreaks havoc on coastal communities and spurs irreversible losses to marine ecosystems. 

Ocean warming has cascading effects, melting polar ice and causing sea-level rise, marine heat waves and ocean acidification, the United Nations’ panel of climate experts made clear on Monday.

Sea-level rise has doubled in the last three decades, reaching a record high in 2021, the Intergovernmental Panel on Climate Change reported. Rising seas, coupled with more extreme weather, are setting the stage for a perfect storm of flooding for coastal communities.

Perceived Biodiversity loss in Mansons Lagoon

Around 30 people trekked around the Spit into Mansons Lagoon, during the July 12 ‘Gumbooting the Lagoon.’ While Jane Newman, from the Cortes Island Museum, explained the site’s human history, marine biologist Deb Cowper and FOCI’s Autumn Barrett-Morgan introduced everyone to intertidal life forms. One of the many topics that arose was the loss of marine life.

One year after the marine die-off

It has been twelve months since billions of marine animals along the West Coast of British Columbia perished during a record breaking heat wave. Temperatures of between 35°C and 40°C were recorded at the Cortes Island School during the last five days of June.
