Late winter – early spring sedimentation off the Great Whale River, southeastern Hudson Bay
Sediment traps were used to measure particle-settling fluxes in serial moorings offshore of Great Whale River (Hudson Bay), both under the late winter sea-ice cover and during and after breakup. Before breakup, the settling fluxes ranged between 0.25 and 2 g cm −2 100 a −1 , increasing from April to...
