Abundance and biomass of zooplankton from 1981-1985 collected in front of Constanta city, Black Sea

The Est Constanta 1981-1985 dataset contains zooplankton data collected allong a 5 station transect in front of the city Constanta (44°10'N, 28°41.5'E – EC1; 44°10'N, 28°47'E – EC2; 44°10'N, 28°54'E – EC3; 44°10'N, 29°08'E – EC4; 44°10'N, 29°22'E – EC5). Zooplankton sampling was undertaken at 5 stations where samples were collected using a Juday closing net in the 0-10, 10-25, 25-50m layer (depending also on the water masses). The dataset includes samples analysed for mesozooplankton species composition and abundance. Sampling volume was estimated by multiplying the mouth area with the wire length. Taxon-specific mesozooplankton abundance was count under microscope. Total abundance is the sum of the counted individuals. Total biomass Fodder, Rotifera , Ctenophora and Noctiluca was estimated using a tabel with wet weight for each species an stage.康斯坦察近海1981-1985数据集（Est Constanta 1981-1985）收录了沿康斯坦察市前方5个站位断面采集的浮游动物数据，各站位坐标如下：EC1：44°10'N，28°41.5'E；EC2：44°10'N，28°47'E；EC3：44°10'N，28°54'E；EC4：44°10'N，29°08'E；EC5：44°10'N，29°22'E。本次浮游动物采样覆盖上述5个站位，采用裘氏闭锁网（Juday closing net）按0~10m、10~25m、25~50m水层分层采集样品，具体分层亦会结合水体团分布进行调整。本数据集包含经分析得到的中型浮游动物（mesozooplankton）物种组成与丰度数据。采样体积通过网口面积与网具绳长的乘积估算获得。各分类单元的中型浮游动物丰度通过显微镜计数得到，总丰度为所有计数个体的总和。轮虫类（Rotifera）、栉水母类（Ctenophora）、夜光藻（Noctiluca）及Fodder类群的总生物量，通过各物种对应发育阶段的湿重参数表估算得到。
