Abstract:

Total Organic Carbon (TOC) concentrations were measured as indicator for past primary productivity on gravity core MSM45_19-2 from the northern Labrador Shelf. Gravity core MSM45_19-2 was obtained during R/V Maria S. Merian expedition MSM45 (58°45.68'N, 61°56.25'W, water depth: 202 m) in 2015 (Schneider et al., 2016). Dry Bulk Density (DBD) was calculated based on sample volume and water content and later used to calculate Marine Accumulation Rates (MAR). The total organic carbon (TOC) content was analyzed (using ELTRA, CS-800) on freeze-dried and homogenized sediment samples, after the removal of carbonates by hydrochloric acid (37%, 500 μl).
