Kerguelen Axis salps and Thysanoessa macrura

Zooplankton were collected with a Rectangular Midwater Trawl (RMT 8+1 net) from 37 sampling sites on and near the Southern Kerguelen Plateau. The contents of each net were preserved in 5% buffered formaldehyde. This dataset covers the counts of the contents of the RMT8 net and includes the abundances for the euphausiid Thysanoessa macrura and the salp Salpa thompsoni. The contents were identified and counted under a Leica M165C stereo-microscope. A flow meter attached to the mouth of the RMT 8 was used to record the volume of seawater passing through the net. The count for Thysanoessa macrura includes the total of all developmental stages. For the salps abundances are shown for the 2 developmental phases - solitary individuals and aggregates.

本数据集使用矩形中层拖网（Rectangular Midwater Trawl，RMT 8+1网）在凯尔盖朗高原南部及周边海域的37个采样站点采集浮游动物样本。各拖网采集的样品均以5%缓冲甲醛溶液固定保存。本数据集包含RMT8网采集样品的计数数据，涵盖磷虾类长额莹虾（Thysanoessa macrura）与海樽类汤氏海樽（Salpa thompsoni）的种群丰度信息。所有样品均在徕卡M165C体式显微镜下完成分类鉴定与个体计数。研究人员在RMT8网的网口加装流量计，以记录流经该网具的海水体积。长额莹虾的计数包含所有发育阶段的个体总量；汤氏海樽的丰度则分别展示了两个发育阶段的个体数量：单独个体与群体聚集个体。
