Accumulation of metals (REEs) in Sediments of the St. Lawrence River (2018-2022)

Characteristics (Grain-size, MO, C, N), major cations and trace metals concentrations in bulk sediments (2018-2022) and suspended sediments (2012) collected in the St. Lawrence River. Suspended sediments were collected by a sediment trap downstream Montreal effluent by Environment and Climate Change Canada. Other data were collected aboard the Lampsilis Research Vessel from UQTR (2018-2021) or by motorboat sampling (2022).
