Optical, chemical, and biological oceanographic conditions on the Scotian Shelf and in the Eastern Gulf of Maine in 2014 /

10 Feb 2016

Surface and deep ocean temperatures were warmer than average overall in the DFO Maritimes Region in 2014, especially in the slope waters and western Scotian Shelf in the second half of the year. [...] In 2014, positive temperature anomalies were most pronounced in the second half of the year, and warm anomalies were most pronounced in slope water and on the western shelf in the fall. [...] Here, we report on the status of nutrients and plankton in the region in 2014 and discuss observations in the context of physical conditions of the marine environment, including both changes in annual mean conditions and recent strong sub-annual and mesoscale variability (Hebert et al. [...] Broad-scale Surveys The highest nitrate concentrations on the sections are observed in the deep waters of the Scotian slope and Cabot Strait, with moderately high nitrate concentrations also observed in the Emerald Basin on the Halifax section (Figure 11a,b). [...] Positive nitrate anomalies were observed in the fall across much of 7 the central and western Cabot Strait section, in deep inshore waters of the Louisbourg section and in the Emerald Basin (Halifax section), and in deep slope water closest to the shelf.
