Physical oceanographic conditions on the Scotian Shelf and in the Gulf of Maine during 1998 [electronic resource] / K.F. Drinkwater, R. Pettipas and L. Petrie
This paper describes temperature and salinity characteristics during 1998 of the waters on the Scotian Shelf and in the Gulf of Maine. The results are derived from data obtained at coastal sea surface stations, long-term monitoring stations, annual groundfish surveys, ships-of-opportunity and research vessels. In order to detect temperature trends the large seasonal cycle has been removed by expressing oceanographic conditions as monthly deviations from their long-term means (anomalies). Where possible, these long-term means have been standardized to a 30-yr average using the base period 1961-1990 in accordance with the convention of the World Meteorological Organization and recommendations of the Northwest Atlantic Fisheries Organization (NAFO).
