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).

本数据集为SES_GR2_Copepod Ingestion on ciliates and phytoplankton 数据集，基于2008年8—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本构建。本研究依据Sesame项目的工作说明（Description of Work，简称DoW），通过航次中所有第三优先级站位开展的实验估算了摄食率（Ingestion rate）。实验所用桡足类（Copepod）采集自水柱上层100米水层，采用网目尺寸为200 µm的网具开展慢速非定量拖网，网具配备大型非过滤式囊网。本次牧食实验选用的桡足类物种包括Clausocalanus furcatus、Oithona spp.、Temora stylifera及Acartia spp.，相关依据参见参考文献（Bamstedt et al. 2000）。桡足类对纤毛虫（Ciliates）的清滤率（Clearance rate）依据Frost公式（Frost 1972）计算得出，摄食率则通过清滤率与初始现存生物量（Standing stocks）相乘得到，相关方法参见参考文献（Bamstedt et al. 2000）。
