Towards a sediment and organic carbon budget for Hudson Bay

A preliminary sediment and organic carbon budget is constructed for the Hudson Bay marine system based on published literature and new data collected from nine rivers and 13 sediment boxcores. The budget considers the main inputs of terrestrial and marine components of sediment and organic carbon and the main sinks (sediment burial) and losses (oxidation, export to Hudson Strait). Sedimentation rates (0.032–0.23 g cm− 2 yr− 1) were estimated...
