Copepod faecal pellets and carbon flux in the coastal sea-ice zone

This dataset contains samples collected at O'Gorman Rocks and Ellis Fjord near Davis station from December 1997 to March 1998. Depth-stratified zooplankton samples were obtained for determination of zooplankton abundance and biomass. Water samples were collected for the determination of chlorophyll a concentration, protist identification and abundance, and the concentration of particulate and dissolved organic carbon. Sediment trap material was collected for the analysis of faecal pellets (identification and CHN analyses), protist identification and abundance, and the measurement of particulate organic carbon concentration. Zooplankton grazing experiments were performed in the laboratory at Davis station and zooplankton were also collected for CHN analyses. Data from this project arose from projects ASAC 963 and ASAC 2229.

本数据集收录了1997年12月至1998年3月期间，于戴维斯站（Davis station）附近的奥戈尔曼岩（O'Gorman Rocks）与埃利斯峡湾（Ellis Fjord）采集的全部样本。研究人员采集了深度分层的浮游动物（zooplankton）样本，用于测定浮游动物的丰度与生物量；采集水样以开展叶绿素a浓度测定、原生生物（protist）种类鉴定与丰度统计，以及颗粒态与溶解态有机碳浓度检测；采集沉积物捕集器样品，用于粪球粒分析（种类鉴定与碳氢氮（CHN）分析）、原生生物种类鉴定与丰度统计，以及颗粒态有机碳浓度测定；在戴维斯站实验室开展了浮游动物牧食实验，并采集浮游动物样本用于碳氢氮（CHN）分析。本项目的数据源自ASAC 963与ASAC 2229两项研究项目。
