The Viruses infecting Sea Lice

Sea lice are a serious problem for the fish farm sector, but a new study from the University of British Columbia has found there are viruses that prey upon them.

“In theory viruses might be deployed in a way in which they might be able to help control sea ice densities in aquaculture. I certainly wouldn’t be a proponent of that at this stage, and would strongly advise against that because we just don’t know enough about it,” explained senior author Dr. Curtis Suttle.

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.

A Breed Apart: What was the Coast Salish woolly dog, and can we bring it back?

Editor’s note:  Salish Woolly dogs are believed to have been common throughout Coast Salish territories, so were most likely kept by the ancestors of the Homalco, Klahoose and Tla’amin First Nations. The oldest remains of this breed date back 4,000 years and were found in Puget Sound and the Salish Sea. Sheep wool is believed to have replaced dog wool in Indigenous communities after 1862.

If you had been wandering the Coast Salish territories of British Columbia some 4,000 years ago, rambling dense woodland and visiting village longhouses, you would likely have spotted a number of small, white, flocculent pooches.

The ocean’s kelp forests are worth serious coin

Canada’s National Observer, Local Journalism Initiative Reporter

Underwater forests represent an average of $500 billion annually in benefits to commercial fisheries, ocean pollution removal and carbon absorption, a new international study shows.

The study is the first to examine the value of kelp’s ocean canopies — found along a third of the world’s shores and on all three of Canada’s coasts, said Canadian co-author Margot Hessing-Lewis, a researcher with the Hakai Institute and the University of British Columbia.

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.
