Heat wave killed far more marine animals than originally thought, says scientist

UBC marine ecologist Dr. Chris Harley initially told the media that more than a billion mussels, clams, sea stars and other invertebrates may have cooked to death in the area between Campbell River and Washington state. That was a ‘back of the envelope’ estimate, based on his observations among the Lower Mainland’s mussel population and some preliminary reports. Harley has done a great deal more research since then. He now guesstimates that, conservatively speaking, the number of marine fatalities during last June’s heat wave is closer to 10 billion.

Extreme marine heat events will devastate global fisheries in the coming decades

Extreme marine high temperature events, such as the one that killed more than a billion shellfish off the West Coast last June, will devastate global fisheries over the decades to come, a new UBC study suggests.

Mansons Lagoon not spared in Marine life die-off

CKTZ News, Local Journalism Initiative Reporter

The lagoon at Mansons Landing is yet another location on Cortes, which experienced alarming rates of marine creature die-off in the wake of the recent heat wave — the sand dollar population being hit the hardest, with losses as high as 85 per cent.

Stranded in the heat, sand, and rocks

There was a boat stranded in the sand, at Smelt Bay, on Saturday. The Woody Point’s anchor lay not too far distant, a testament to its owner’s original intention. The ocean was perhaps another hundred feet distant. 

CKTZ News came to take pictures for another story. Thousands of mussels died on the exposed rocks at the southern side of the beach. They were presumably casualties of the heatwave that ravaged shellfish populations throughout the West Coast almost two weeks ago.

Abnormally high number of Shellfish deaths on Cortes Island

CKTZ News, Local Journalism Initiative Reporter

In the midst of a heat wave that may have left as many as a billion dead marine creatures along the West Coast, there appears to have been an abnormally high number of shellfish deaths reported at a number of Cortes Island locations. 

Daily temperature highs of between 35°C and 40°C were recorded, at the Cortes Island School, during the last five days of June.
