Ocean temperature time series in the Scotian Shelf and one for the Bay of Fundy collected by DFO monitoring programs. Long-term increases are observed from in situ sea surface temperature (0 m, 1947–2016, positive trend of 0.15°C per decade, significant at 1% level) and for the deeper layer (250 m, 1947–2016, positive trend of 0.36°C per decade, significant at 1% level) of the Emerald Basin region of the Scotian Shelf. Depth-averaged ocean temperature (0–90 m) from the Prince 5 station in the Bay of Fundy (1924–2016, positive trend of 0.16°C per decade, significant at 1% level) indicates a similar long-term warming trend.
