Lengths of key zooplankton species in the Indian Sector of the Southern Ocean

Zooplankton were collected during the winter-spring transition during two cruises of the Aurora Australis: SIPEX in 2007 and SIPEX II in 2012. To determine size and biomass, key species were measured. Measurements of Prosome, Urosome and Total length are provided. The zooplankton were taken from samples collected with umbrella nets, RMT1 net and sea ice cores. They were measured under a Leica M165C steromicroscope using an ocular micrometer. The ocular micrometer was calibrated against a stage micrometer (+/- 0.01 um).

本数据集的浮游动物（Zooplankton）样本采集自澳极光号（Aurora Australis）科考船的两次航次——2007年的SIPEX航次与2012年的SIPEX II航次，采样时段为冬春过渡季节。为测定浮游动物的体型与生物量，研究人员针对关键物种开展了测量工作，本次数据集包含前体部（Prosome）、后体部（Urosome）及总长度（Total length）的测量结果。本次研究的浮游动物样本取自伞形网、RMT1拖网以及海冰岩心的采集样品；所有测量均在徕卡M165C体视显微镜（stereomicroscope）下完成，采用目镜测微尺（ocular micrometer）进行尺寸读数。实验前以载物台测微尺（stage micrometer）对目镜测微尺进行校准，校准误差为±0.01微米。
