Subset of zooplankton abundance and biomass time series from net hauls at site L4 off Plymouth, UK between 1988-2020.

Ongoing zooplankton research at the Plymouth Marine Laboratory has established a time series of zooplankton species since 1988 at L4, a coastal station off Plymouth, UK. Weekly samples are collected by vertical net hauls (WP2 net, mesh 200 µm; UNESCO 1968) from the sea floor (approximately 50 m) to the surface and stored in 4% buffered formalin. This data set represents a subset of taxa from L4 zooplankton time series 1988-2020 v25082021 doi: 10/gzh6. Abundance results presented are number m^-3 mean values from two replicate hauls made on each sampling timepoint. Biomass results are µg C m^-3. Please see file L4 Zooplankton biomass_method protocols v24112021 for more information on this. It is encouraged that users of the data maintain contact with originators of the dataset to prevent misuse or misunderstanding of the data provided due to the complex nature and temporal coverage of the data provided.

英国普利茅斯海洋实验室（Plymouth Marine Laboratory）正在开展的浮游动物研究，构建了自1988年起于英国普利茅斯近海L4沿岸站位获取的浮游动物物种时间序列数据集。研究人员采用垂直拖网法（WP2型拖网（WP2 net），网目200微米（µm）；参照联合国教科文组织1968年标准（UNESCO 1968））采集每周样本，采样深度范围从海底（约50米水深）至海水表层，采集后的样本以4%缓冲福尔马林溶液固定保存。本数据集为1988-2020年L4浮游动物时间序列v25082021版本（DOI：10/gzh6）的类群子集。本次公布的丰度结果为每个采样时间点两次重复拖网的均值，单位为个·m⁻³；生物量结果单位为微克碳·m⁻³（µg C m⁻³）。有关详细信息，请参阅《L4浮游动物生物量测定方法规程v24112021》文件。鉴于本数据集具有复杂的特性与较长的时间覆盖范围，建议数据使用者与数据集原始创建者保持沟通，以避免出现数据误用或解读偏差的情况。
