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.

埃斯特·康斯坦察1981-1985年数据集收录了康斯坦察市近海沿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）。本次采样在上述5个站位开展，采用Juday闭锁式网（Juday closing net）于0-10m、10-25m、25-50m水层采集浮游动物样品，采样水层会根据实际水团情况进行调整。本数据集包含经分析的中型浮游动物（mesozooplankton）物种组成与丰度相关样品数据。采样体积通过网口面积与曳网长度的乘积计算得到。研究人员在显微镜下计数各分类单元的中型浮游动物丰度，总丰度为所有计数个体的总和。轮虫（Rotifera）、栉水母类（Ctenophora）、夜光藻（Noctiluca）及Fodder类群的总生物量，通过各物种与发育阶段的湿重对应表进行估算。
