Zooplankton sampling in the coastal waters of south eastern Tasmania

Zooplankton was counted and identified from three sites over the 5-year period. The net used (200 m Bongo net) was designed to catch meso-zooplankton with an integrated vertical tow through the water column. One net from each of the paired Bongo samples was analysed and the data expressed as numbers per m3. Copepods dominated the zooplankton, with other groups such as salps, krill, appendicularians, cladocerans, chaetognaths and meroplanktonic larvae being seasonally dominant.

本数据集针对5年监测周期内3个采样站点的浮游动物完成了计数与种类鉴定工作。所用采样网具为孔径200μm的邦戈网（Bongo net），该设备专为采集中层浮游动物（meso-zooplankton）设计，采用整层水柱垂直拖曳的采样方式完成采样。本研究对成对邦戈网采集样品中的一张滤样进行了分析，最终数据以每立方米水体中的个体数量为单位进行统计表征。桡足类（Copepods）为本次采样获得的浮游动物优势类群，其余类群如海樽、磷虾、尾海鞘类、枝角类、毛颚类以及季节性浮游幼体则呈现出季节性优势分布特征。
