Abundance of microplankton in the eastern Mediterranean Sea in April 2008 during SES_GR2

The dataset is based on samples taken from 12 stations in Northern Aegean Sea, Southern Aegean Sea, Ionian Sea and Libyan Sea during August-September 2008. 12 Niskin bottles (8lt) made by PVC with rubber coated o rings and stainless steel ss springs. Seawater samples (150 mL) were collected from selected depths of the water column (2, 20, 50, 75, 100 m) for the identification and enumeration of phytoplankton cells (>= 5 µm). The samples were fixed with Lugol solution and concentrated to 25 mL by sedimentation. Phytoplankton species abundance was determined with an inverted light microscope (OLYMPUS IX70) according to the Utermohl method (Utermohl, 1958).

本数据集基于2008年8月至9月期间，从爱琴海北部、爱琴海南部、爱奥尼亚海以及利比亚海的12个采样站点采集的样本构建。本次采样使用12个容积为8升的尼森瓶（Niskin bottles），该类瓶子以聚氯乙烯（PVC）为材质，配备橡胶包覆的O形圈与不锈钢弹簧。研究人员从水柱的2、20、50、75、100米选定深度处采集150毫升海水样本，用于鉴定并计数粒径≥5微米的浮游植物细胞。样本采用鲁哥氏液（Lugol solution）固定，并通过沉淀法浓缩至25毫升。浮游植物物种丰度通过倒置光学显微镜（OLYMPUS IX70）依据乌特莫尔法（Utermohl, 1958）进行测定。
