Ocean temperatures off N.S. dip after record breaking year, have moved back to normal
Following a season of record-breaking surface temperatures last year, ocean temperatures in the waters around Nova Scotia have moved back to normal this summer, says the Department of Fisheries and Oceans.,,, In 2018, DFO found winter sea surface temperatures from the Scotian Shelf to the Bay of Fundy were above normal. There were also record-breaking temperatures in August and September. However, DFO’s spring survey conducted in April 2019 differed from last year’s results. “First, the surface was really cold because we had a really cold winter. It takes time for the ocean to heat up,” Hebert said. “The deeper water seemed to be back to the normal temperature.” >click to read< 09:44
Warming trend continues in waters off Atlantic Canada
Warmer ocean temperatures off Atlantic Canada continued in 2016, maintaining a trend that started earlier this decade, according to survey results from Canada’s Department of Fisheries and Oceans. On the Scotian Shelf off Nova Scotia, temperatures last year were as high as three degrees above the 30-year average used to establish climatic norms. “It’s not quite the same [record] level of 2012, but it’s getting close to it,” said Dave Hebert, a research scientist with DFO. He added that 2016 was probably the second warmest year on record. Scientists have struggled to explain what is causing the most intriguing aspect of the recent trend: the warming of ocean bottom water, which is not influenced by surface weather events. Hebert said the latest theory is based on model results that see the Gulf Stream moving northward and intersecting with the tail of the Grand Banks. “That is stopping the cold Labrador Sea water from coming around the tail of the Grand Banks,” he said. “That’s where we normally get the cold water that refreshes the [Scotian] Shelf. That hasn’t been happening. Read the story here 16:48
