Stable carbon isotope, inorganic carbon, and brassicasterol data from sea ice and open water particulate matter, sediments, and benthic consumers in the Arctic, Chukchi, and Beaufort seas, 2014

This data set contains stable carbon isotope values of dissolved inorganic carbon from pore water in sea ice, as well as IP25 and brassicasterol data, from sea ice and open water particulate organic matter, sediments, and benthic consumers in the Arctic, Chukchi, and Beaufort seas. We quantified the sea ice algal biomarker IP25 and the phytoplankton biomarker brassicasterol in ice-associated particulate organic matter (iPOM), open water particulate organic matter (pPOM), surface sediments, and various benthic invertebrates to determine the fate of iPOM in the Chukchi and Beaufort seas. All samples were collected July - August 2012, October - November 2013, and May - June in 2014.

本数据集涵盖北极、楚科奇海与波弗特海海域海冰孔隙水中溶解无机碳的稳定碳同位素比值，以及采自该海域海冰、开阔水体颗粒有机质、沉积物和底栖生物的IP25与brassicasterol相关数据。研究团队对冰附着颗粒有机质（ice-associated particulate organic matter, iPOM）、开阔水体颗粒有机质（open water particulate organic matter, pPOM）、表层沉积物及多种底栖无脊椎动物中的海冰藻类生物标志物IP25和浮游植物生物标志物brassicasterol进行了定量分析，以探明楚科奇海与波弗特海海域冰附着颗粒有机质的归宿。所有样品采集于2012年7—8月、2013年10—11月及2014年5—6月。
