Ingestion rate on ciliates and phytoplankton collected in the upper 100m in the eastern Mediterranean Sea based on samples from August-September 2008 during SES_GR2

The SES_GR2_Copepod Ingestion on ciliates and phytoplankton dataset is based on samples taken during August-September 2008 in Ionian Sea, Libyan Sea, Southern Aegean Sea and Northern Aegean Sea. Ingestion rates were estimated from experiments performed at all the third priority stations during the cruise according to DoW of Sesame project. Copepods for the experiments were obtained with slow non-quantitative tows from the upper 100 m layer of the water column using 200 µm mesh size nets fitted with a large non-filtering cod end. For the grazing experiments we used the following copepod species: Clausocalanus furcatus, Oithona spp. Temora stylifera and Acartia spp according to the relevant reference (Bamstedt et al. 2000). Copepod clearance rates on ciliates were calculated according to Frost equations (Frost 1972). Ingestion rates were calculated by multiplying clearance rates by the initial standing stocks (Bamstedt et al. 2000).

SES_GR2_桡足类纤毛虫与浮游植物摄食数据集（SES_GR2_Copepod Ingestion on ciliates and phytoplankton dataset）基于2008年8月至9月在爱奥尼亚海、利比亚海、南爱琴海及北爱琴海采集的样品构建。本数据集的摄食速率通过航次内所有第三优先级站位的实验数据估算得到，实验流程严格遵循Sesame项目的工作大纲（DoW）要求。实验所用桡足类采自水柱上层100 m水层，采用配备大型非过滤型囊网的200 μm网目尺寸拖网，以慢速非定量拖曳方式获取。本牧食实验所用桡足类物种如下：锤真哲水蚤（Clausocalanus furcatus）、大眼剑水蚤属（Oithona spp.）、细长哲水蚤（Temora stylifera）以及歪水蚤属（Acartia spp.），实验设计参考相关文献（Bamstedt等，2000）。桡足类对纤毛虫的清滤速率依据Frost公式（Frost，1972）计算得到。摄食速率则通过清滤速率与初始现存生物量的乘积计算得出（Bamstedt等，2000）。
