Abundance and biomass of mesozooplankton from the S-R01 cruise in the western part of the Black Sea in April 2008

The SESAME dataset contains mesozooplankton data collected during April 2008 in the North-West Black Sea (between 44°46' N and 42°29'N latitude and 28°64'E and 30°59'E longitude). Mesozooplankton sampling was undertaken at 9 stations where samples were collected using a Nansen closing net in the 0-10, 10-25, 25-50, 50-100, 100-150, 150-180 m layer. The dataset includes 28 samples analysed for mesozooplankton species composition, species abundance and total biomass. The Taxon-specific mesozooplankton abundance sample or aliquots were analyzed under the binocular microscope. Taxonomic identification was done according to Morduhai-Boltovskii et al. 1968. Total biomass was estimated using a tabel with wet weight for each species an stage (Petipa method).SESAME数据集包含2008年4月于西北黑海（纬度范围44°46'N至42°29'N，经度范围28°64'E至30°59'E）采集的中型浮游动物（mesozooplankton）数据。研究于9个站位开展中型浮游动物采样，使用南森闭锁网（Nansen closing net）按0-10 m、10-25 m、25-50 m、50-100 m、100-150 m、150-180 m水层分层采集样品。数据集共收录28份样品，用于分析中型浮游动物的物种组成、物种丰度及总生物量。 针对每份中型浮游动物样品或其分样，通过双目显微镜开展物种特异性丰度分析。物种分类鉴定依据Morduhai-Boltovskii等（1968）的研究方法完成。 总生物量采用佩蒂帕法（Petipa method），通过匹配各物种及发育阶段的湿重对照表进行估算。
