Patterns of recent sedimentation in Hudson Bay
Hudson Bay is a large Arctic/sub-Arctic shelf sea that covers an area of approximately 841,000 km2, and is estuarine in character, with a large watershed and more than 40 rivers discharging into the bay. Sediment core data for 18 new cores in Hudson Bay was used to understand the processes effecting...

Hudson Bay is a large Arctic/sub-Arctic shelf sea that covers an area of approximately 841,000 km2, and is estuarine in character, with a large watershed and more than 40 rivers discharging into the bay.
