The presented data originates from the 1306cm long gravity core MSM45-19-2 (58°45.68 N, 61°56.25 W, 202m water depth) taken during R/V Maria S. Merian cruise MSM45 in August 2015 at 202 m water depth on the northern Labrador Shelf, northeast Canada, northwest Atlantic. In order to fully understand the dynamics that contributed to the establishment of modern Labrador Sea circulation, detailed reconstructions of the major paleoceanographic changes through the Holocene are critical. Therefore, this study aims to provide new information on bottom (i.e. subsurface) water mass composition as well as on changes in primary productivity and sea-ice conditions in the LC during the Holocene. Reconstructions are based on benthic foraminiferal assemblages.Foraminiferal assemblages were counted in 15–20 and 50-cm intervals between 0–200 and 200–1300 cm core depth, respectively. Sample resolution in the upper core section was increased because of lower sedimentation rates. Each sample contained about 20 mL of wet sediment ...
