A hydrographic section across Hudson Strait was occupied over September 25-26, 2009 by Research Vessel (R/V) Knorr. Twelve profiles of temperature, salinity, and beam transmission were collected between Big Island and Wales Island. The profiles were collected with a Seabird 9 Conductivity-Temperature-Depth (CTD). The profiles were manually examined and are provided as 1-meter (m) bin averages. Also provided are bathymetry data collected by R/V Knorr's Knudsen depth sounder. The purpose of the cruise was to recover four moorings deployed in the Strait to capture a year-long time series of the inflow and outflow. 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.
