209 PCB congener concentrations, sedimentary parameters and MDLs in the East Siberian Sea and Chukchi Sea

This is the supplementary material for the article "Biogeochemical controls on PCB accumulation in the East Siberian Arctic Shelf", which includes data on the concentrations of 209 PCB congeners in surface sediments from the Chukchi Sea and the East Siberian Sea, sedimentary parameters at the sampling stations, the method detection limits , as well as data on the concentrations of PCBs in the bottom layer of a sediment core (0-12 cm) from the Bering Sea.
