Finnish Baltic Sea zooplankton monitoring

The dataset include Finnish zooplankton monitoring data from the Baltic Sea. The Finnish zooplankton monitoring program started in 1979 and is still ongoing. The sampling has normally taken place in late summer (August), but since 2014 sampling is also carried out in early summer (May-June).The zooplankton monitoring was performed by Finnish Institute of Marine Research until 2008, thereafter the Finnish Environment Institute is responsible for the monitoring program. Samples are taken using a WP-2 net (normally 2550 cm2 opening and 100 um mesh size). The monitoring follows the HELCOM COMBINE guidelines, but subsampling is done using Folsom splitter. The dataset is also accessible through the NOAA COPEPOD database.本数据集包含波罗的海芬兰海域浮游动物（zooplankton）监测数据。芬兰浮游动物监测项目始于1979年，至今仍在持续开展。该监测的采样工作通常于夏末（8月）进行，自2014年起增设初夏（5-6月）采样环节。2008年以前，浮游动物监测工作由芬兰海洋研究所（Finnish Institute of Marine Research）承担；自2008年起，该监测项目的主管单位变更为芬兰环境研究所（Finnish Environment Institute）。采样采用WP-2网开展，该网通常网口面积为2550平方厘米，网孔孔径为100微米。本次监测严格遵循HELCOM联合指南（HELCOM COMBINE guidelines），分样环节采用福尔萨姆分样器（Folsom splitter）完成。本数据集亦可通过美国国家海洋和大气管理局（NOAA）桡足类数据库（COPEPOD）获取。
