Four moorings were deployed across Hudson Strait between Big Island and Wales Island from August 2008 to September 2009 to map the seasonal variability in properties and transports of the Strait. Hudson Strait is the main pathway of heat, mass, and freshwater exchange between Hudson Bay and the Arctic and North Atlantic Oceans. Hudson Strait inflow affects the physical and biogeochemical cycles and ecosystems of Hudson Bay. One mooring was deployed near the southern coast to capture the outflow. Three moorings were deployed on the northern side to capture the inflow. Two moorings were instrumented with Aquadopps, providing point velocity measurements of the deep currents, and two moorings were instrumented with Acoustic Doppler Current Profilers, providing profiles of the surface currents. The current meter data were processed according to their manufacturer specifications; each record was manually examined to remove obviously spurious data.
