Abstract: ► Mass accumulation rates (MAR) in the abyssal Black Sea were 61 to 76 g m⁻² yr⁻¹. ► These values point to increasing MARs for the past century. ► In the cores with turbidites, we used Chernobyl-derived Cs-137 to compute MAR. ► In turbidite-impacted cores, MAR can be as high as 5230 g m⁻² yr⁻¹. ► Fast deposition was reflected in the pyrite sulfur isotopic ratios as well.
