Water temperatures in the Gulf of St. Lawrence have reached record highs, experts warn

New data shows that water temperatures in the Gulf of St. Lawrence have reached record highs, with experts warning the increase could impact some species that live in the waters.

According to new research, published Tuesday by Fisheries and Oceans Canada, warming ocean temperatures -- specifically those in deep water -- set more records in the Gulf of St. Lawrence in 2021 than in the past 40 years.

The findings include that water temperatures at depths of 200, 250 and 300 metres hit highs of 5.7 C, 6.6 C and 6.8 C, respectively, over the past year.

Department of Fisheries and Oceans scientist Peter Galbraith analyzed the temperature changes in the different layers of the water. He told CTV National News that the temperatures in the "cold intermediate layer" of the water are the warmest scientists have seen since they began collecting such data.

Galbraith says the change in temperatures has happened quite suddenly, posing a risk to species in the gulf that may not be able to quickly adapt.
