Seawater Quality Seawater is supplied to the Life Sciences Centre by three 400 USgpm pumps, operating in parallel. A fully dedicated emergency diesel generator in the pumphouse supplies electricity during power failures. Water is drawn from the North West Arm, a flooded glacial gouge extending some 4 km inland from Halifax Harbour. Salinity and temperature values are well correlated with those of Scotian Shelf waters. Salinity is fairly constant at about 31 ppt.
Temperature follows a seasonal cycle.
