Sedimentation, bioturbation, and Hg uptake in the sediments of the estuary and Gulf of St. Lawrence

Sedimentation rates and mixing depths have been estimated from the application of a two-layer biodiffusion model to 210Pb profiles in sediment cores collected in the Laurentian Trough in the Estuary and Gulf of St. Lawrence. Sedimentation rates decrease exponentially with distance seaward from 0.70 cm yr21 (0.47 g cm22 yr21) near the head of the Trough to 0.04 cm yr21 (0.03 g cm22 yr21) in the ...
