We collected samples at basic, mooring and CTD (conductivity-temperature-depth) stations, as well as along two transects made by Zodiac near the mouth of the Rivière de la Grande Baleine and off Cape Tatnam, located at ca. 100 km East of the Nelson River. All water samples were filtered on board, and subsamples were retained for analysis for dissolved and particulate organic carbon and nitrogen, as well as for phosphate, total soluble salts (TSS), chlorophyll a, CDOM (absorbtion and fluorescence spectra), oxygen-18 and salinity. At each station, water column profiles were recorded, each to the bottom or at least 30 m depth, using an Idronaut CTD with conductivity, temperature, depth and turbidity sensors, and a WetLabs ECO Fluorometer for CDOM fluorescence. In addition,we made several water column profiles of absorption and attenuation spectra off the mouth of the Rivière de la Grande Baleine, using a WetLabs hyperspectral absorption and attenuation meter (WetLabs acs). We also recorded miscellaneous water surface reflectance spectra, using a Satlantic HyperSAS instrument mounted on the ship's bow, near Rivière de la Grande Baleine, near the mouth of James Bay and in the outer estuary of the Nelson River. These data were collected opportunistically during a cruise of the CCGS Amundsen that started from Quebec City to end in Churchill, MB. The main purpose of the expedition was to retrieve and redeploy ArcticNet oceanographic moorings. This dataset supplement data collected previously in Hudson Bay to support studies from the University of Manitoba on freshwater-marine interactions in Hudson Bay. These studies include freshwater sources (fluvial and ice-melt), distribution and circulation in Hudson Bay and Hudson Strait, nutrient and sediment loading from two major rivers (the Nelson River and the Rivière de la Grande Baleine), and optical effects of CDOM (colored dissolved organic matter) and sediments on the littoral of Hudson Bay.
