Biological Sample Benthos (MR16-06)

As a part of an ArCS subproject (marine ecosystem group in the theme 6), sea bottom sediments were sampled by Smith and McIntyre grab sampler at 23 cites in Bering Sea and Chukchi Sea. Sediment samples are processed and analyzed to understand particulate organic carbon (POC) contents, chlorophyll contents, persistent organic pollutants (POPs) contents, biomass and species composition of Macro-benthos in the sediment. The data set contributes to quantify "positive impact" (i.e., food supply) and "negative impact" (i.e., bioaccumulation of POPs) to the marine food web.
