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.

本数据集作为ArCS子项目（主题6下的海洋生态系统研究组）的一部分，研究人员采用Smith-McIntyre采泥器（Smith and McIntyre grab sampler）在白令海与楚科奇海的23个采样点采集了海底沉积物样品。随后对沉积物样品进行处理与分析，以测定其中的颗粒有机碳（POC）、叶绿素、持久性有机污染物（POPs）含量，以及沉积物中大型底栖生物（Macro-benthos）的生物量与物种组成。本数据集可用于量化海洋食物网所承受的“正向影响”（即食物供给）与“负向影响”（即持久性有机污染物的生物富集作用）。
