Abundance and biomass of phytoplankton in the western part of the Black Sea during the R/V Akademik cruise Ak082001 in August 2001@en

The dataset is composed of 41 samples from 10 stations. The phytoplankton samples were collected by 5l Niskin bottles attached to the CTD system. The sampling depths were selected according to the CTD profile and the in situ fluorometer readings: surface, temperature, salinity and fluorescence gradients and 1 m above the bottom. At some stations phytoplankton net samples (20 µm mesh-size) were collected to assist species biodiversity examination. The samples (1l sea water) were preserved in 4% buffered to pH 8-8.2 with disodiumtetraborate formaldehyde solution and stored in plastic containers. On board at each station few live samples were qualitatively examined under microscope for preliminary analysis of taxonomic composition and dominant species. […]本数据集涵盖10个采样站的41份样品。浮游植物样品由挂载于CTD系统（Conductivity-Temperature-Depth系统）的5升尼斯金采水器（Niskin bottles）采集完成。采样深度依据CTD剖面与现场荧光计读数选取：表层、温度梯度层、盐度梯度层、荧光梯度层以及底床上方1米处。部分采样站额外采集了网孔尺寸为20μm的浮游植物网采样品，以辅助物种多样性考察。每份取自1升海水的样品，使用经四硼酸钠缓冲至pH 8~8.2的4%甲醛溶液进行固定保存，并储存在塑料容器中。在船上，每个采样站均会取少量鲜活样品置于显微镜下开展定性检测，以初步分析样品的分类组成与优势物种。[…]
