Physical oceanographic conditions on the Scotian Shelf and in the Gulf of Maine during 2024 / by Chantelle Layton, David Brickman, Blair Greenan, Peter S. Galbraith and Jean-Luc Shaw.: Fs97-18/403E-PDF

"The physical oceanographic conditions on the Scotian Shelf and in the Gulf of Maine observed in 2024 are presented. Mean annual air temperature anomalies relative to 1991-2020 climatology, at six sites were positive. Satellite-based Sea Surface Temperature (SST) annual anomalies were also positive for all seven subregions based on NAFO areas. Long-term coastal monitoring at Halifax (Nova Scotia) recorded the tenth highest value annual SST and at St. Andrews (New Brunswick) the fourth highest value. At selected sites across the region, three of the six annual bottom water temperatures were above normal, two normal, and one below normal. Four of the regions were cooler than the previous year. A composite index, consisting of 22 ocean temperature time series from surface to bottom across the region indicated that 2024 was primarily above normal with 9 of the time series greater than one standard deviation"--Abstract, page v.
