The annual load and the composition of material exported to the coast of Hudson Bay were characterized and modelled over the hydrological cycle of the Great Whale River. Annual exportations of particulate inorganic matter (PIM), particulate organic matter (POM), and dissolved organic carbon (DOC) to Hudson Bay were estimated at 135 000, 21 000, and 90 000 t, respectively. PIM, POM, and DOC concentrations were positively related to discharge, as were concentrations of coarse (>1 mm), fine (53 µ-1mm), and very fine (0.7-53 µ) particulate organic matter. Of the three size fractions, very fine particulate organic matter exhibited the highest heterotrophic activity, the lowest C :N ration, and the highest chlorophyll a concentration (1 µg•L-1 during summer. During the ice break up period, 25-35 % of the yearly PIM load, 23% of the POM load, 11 % of the DOC load, and 5-14 % of the dissolved nutrient load were exported to Hudson Bay. River waters were less concentrated in nutrients than Hudson Bay coastal waters. Comparison of DOC output with that of 46 other rivers draining the Precambrian Shield shows that, for a given runoff value, rivers flowing through tundra to Hudson and Ungava bays carried a specific DOC load aout half that of rivers flowing through forested basins to the Gulf of St. Lawrence.

Echo integration, a multistage plankton sampler (BIONESS), and a bottom trawl were used to examine the horizontal and vertical distribution of shrimp (Pandalus montagui) near Resolution Island in eastern Hudson Strait. Shrimp were concentrated in two locations within the study area and they maintained this pattern of horizontal distribution for at least 7 d. Acoustic observations revealed a scale of horizontal patchiness that was obscured by the "homogenization effect" of sampling by bottom trawl and plankton net. The shrimp underwent a nocturnal vertical migration with other zooplankton to > 200 m from the bottom and a subsequent downward migration during early daylight hours. This diel migration resulted in reduced availability of shrimp to the bottom trawl at night. Timing of the migrations varied, possibly as a result of interaction with oceanographic processes.©1992 Minister of Supply and Services Canada

Greenland cod populations near Wemindji, eastern James Bay, were studied in 1987 and 1988 to describe the species' general ecology and life-history characteristics. During the summer, they principally occupied shallow (2–5 m) coastal waters. This habitat was characterized by a belt of eelgrass (Zostera marina) at depths of 1–3 m, salinities between 20 and 23 ‰, and temperatures of 3–20 °C. Daily trap catches were highly variable, and more fish were caught at night than during the day. In winter, more cod were found inshore, in the estuary, than in coastal waters. This movement corresponds to the completion of sexual maturity; spawning occurs in April to June. Growth rate was linear for males and females. The age at maturity was 3 years and no trade-off was observed between growth and reproduction. Greenland cod spawned every year, and the maximum age was 9 years. Life-history variables for Greenland cod differ from those of most arctic benthic fishes; this species shows rapid growth, high fecundity, low age at maturity, and high mortality. These characteristics may represent important adaptations allowing cod to sustain life in James Bay coastal waters, where environmental conditions are different from those in arctic waters.©1991 National Research Council Canada
