Stable isotopes for POM and grazers (zooplankton) collected during the SIPEX and SIPEX II voyages

Zooplankton were collected during the winter-spring transition during two cruises of the Aurora Australis: SIPEX in 2007 and SIPEX II in 2012. As part of the collections sea ice cores were collected to describe the ice habitat during the period of zooplankton collections. Ice cores were taken with a 20 cm diameter SIPRE corer and sectioned in the field with an ice core. Particulate organic matter (POM) and animals from the zooplankton (water column) and the sea ice cover (meiofauna) were processed for stable isotopes - delta 13 Carbon and delta 15 Nitrogen.

本数据集的样本采集于2007年SIPEX与2012年SIPEX II两次"南极光号"（Aurora Australis）科考船的冬春过渡航次，期间采集了浮游动物（zooplankton）样本。作为采样工作的组成部分，同步获取海冰岩芯（sea ice cores）以表征浮游动物采样时段内的海冰生境。海冰岩芯采用直径20厘米的SIPRE型取芯器（SIPRE corer）采集，并在野外借助冰芯工具完成分段处理。针对颗粒有机物（POM, particulate organic matter）、水体层浮游动物以及海冰覆盖区的小型后生动物（meiofauna）样本，开展了碳稳定同位素（δ¹³C）与氮稳定同位素（δ¹⁵N）分析。
