Heatwave – Shocked by mass death

North America has recently noticed extreme temperatures. Canada is constantly breaking new heat records, and a number of people visit hospital as a result of the violent heat.

The heat wave has led to hundreds of deaths in both the United States and Canada.

However, it is not just people who are affected by the high temperatures.

Marine biologist Christopher Harley estimates that over one billion shellfish along the Canadian Pacific coast may have died as a result of the abnormal heat.

Never smelled like that

Harley tells Dagbladet that he was greeted by a violent heat and strong smell when he arrived on the coast.

– The researcher in me was of course very fascinated, but it quickly turned into shock when I then realized how extensive this was, says Harley.

In addition to extreme amounts of mussels, there were also snails, starfish and mussels that lay rotten by the water’s edge. Harley describes it all as an overwhelming experience.

– I do not remember having seen or smelled anything similar before.

Think the numbers are surprising

After the startling discovery, the marine biologist chose to take a closer look at other coastlines.

– Every time I think I’ve seen the worst beach, I find another one shortly afterwards with more destruction.

Very rare

– Mass deaths are very rare, and this is unparalleled. During 25 years of research, I have seen two minor cases. There have never been so many over such a large area, says Harley.

Devastated by a new heat wave

Harley tells The Guardian that he has also received reports from colleagues about dead sea anemones, stonefish and oysters.

Mass deaths of shellfish can also affect water quality, because mussels and mussels help to filter the water.

– I have talked to people who have lived by the coastline for decades – none of them have ever seen anything like it, says Harley.

Heat wave

According to the marine biologist, mussels cannot survive at temperatures of more than 38 degrees for a long time. He and a student at the University of British Columbia used a heat-seeking camera to estimate the surface temperature in the area. They measured a temperature of over 50 degrees.

A heat wave is currently raging over large parts of North America. Canada has set a new heat record of 49.6 degrees and milder temperatures are not expected immediately, reports Dagsavisen.
