Ingestion rate and egg production of copepods collected in the upper 100m in the eastern Mediterranean Sea in March and April 2008 during SES_GR1

The phytoplankton dataset is based on samples taken during March-April 2008 in 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: Calanus helgolandicus and Centropages typicus 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).

浮游植物数据集基于2008年3月至4月在利比亚海、南爱琴海及北爱琴海采集的样本构建。摄食率通过航次期间在所有第三优先级站点开展的实验估算得出，实验方法遵循Sesame项目的工作文件（DoW）。实验所用桡足类通过以下方式获取：使用装配有大型非过滤网囊的200微米孔径网，在水体上层100米进行慢速非定量拖网。摄食实验选用的桡足类物种为：Calanus helgolandicus和Centropages typicus，物种选择依据相关参考文献（Bamstedt等，2000）。桡足类对纤毛虫的清除率根据弗罗斯特方程（Frost，1972）计算；摄食率则通过清除率乘以初始现存量得出（Bamstedt等，2000）。
