From great white sharks around Quebec's Îles-de-la-Madeleine to lobsters conquering new territory, oceanographers say the warming of the Gulf of St. Lawrence is having an impact on the creatures that live in its unique ecosystem. Data from Fisheries and Oceans Canada show that deepwater temperatures have been increasing overall in the gulf since 2009. In 2022, gulf-wide average temperatures hit new record highs at depths of 150 to 300 metres, and passed the threshold of 7 C at 300 metres for the first time. Average monthly temperatures at the sea surface also set new records in August and September, the data showed.
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.
'Everything about the Gulf of St. Lawrence was warmer in 2021': federal scientist
Warming ocean temperatures — especially in deep water — set more records in the Gulf of St. Lawrence in 2021, according to climate data released Tuesday by the Department of Fisheries and Oceans. "Everything about the Gulf of St. Lawrence was warmer in 2021," said federal research scientist Peter Galbraith, based at the Lamontagne Institute in Mont-Joli, Que.
How undersea aquifers could become a source of fresh water for coastal communities
Groundwater under the sea floor off the coast of Prince Edward Island could solve a host of problems for the Island, but there are a lot of questions that need to be answered first. The research vessel Maria S. Merian is currently off the North Shore of P.E.I., using various techniques to search for groundwater below the bottom of the Gulf of St. Lawrence. "P.E.I. is 100 per cent reliant on groundwater and it's a finite resource, and we are very cautious with how we use it, as we should be," said Josh MacFadyen, the Canada Research Chair in Geospatial Humanities at the University of Prince Edward Island.
Deep water temperatures hit 'scary' highs in Gulf of St. Lawrence
A decade-long warming trend in the Gulf of St. Lawrence continued in 2020 with deep waters reaching record highs, according to ocean climate data released Tuesday by the Department of Fisheries and Oceans. Water temperatures at depths of 200, 250 and 300 metres were higher than any measured in the Gulf since records started in 1915, hitting highs of 5.7 C, 6.6 C and 6.8 C. All were well above the normal variations.
