Ocean temperatures in Atlantic Canada set record highs again in 2022, according to the latest assessment released by the federal Department of Fisheries and Oceans. Results from the annual Atlantic Zone Monitoring Program show surface, intermediate and bottom temperatures were well above normal last year. "It was widespread. It was everywhere," said Peter Galbraith, a DFO research scientist in Mont-Joli, Que. "It was really, really warm across the zone."
Ocean temperatures are off the charts right now, and scientists are alarmed
What’s behind this rapid increase isn’t totally clear yet. “These temperatures just rocketed up, people haven’t had a chance to puzzle it all out,” Johnson said. Some scientists are concerned the scale of these new records could mark the start of an alarming trend. Others say record-breaking temperatures like these are always concerning but to be expected given the human-caused climate crisis. All agree the consequences are likely to be significant. Warmer oceans bleach coral, kill marine life, increase sea level rise and make the ocean less efficient at absorbing planet-warming pollution – the warmer oceans get, the more the planet will heat.
Ocean temperatures soared to new 'pretty alarming' highs off Nova Scotia in 2022
Ocean temperatures off Nova Scotia hit record highs last summer, eclipsing the record-breaking temperatures set in the Atlantic a decade earlier. "It's pretty alarming," said Fisheries and Oceans Canada research scientist Chantelle Layton. Layton is part of the DFO team analyzing results from the annual Atlantic Ocean monitoring program in eastern Canada. Canadian scientists are discussing the 2022 data this week.
