Zooplankton abundance and environmental variables at weathership station India, 59o N 19o W, from 1974 to 1975

<ns3:p> This dataset was collected between 1971 and 1975 at Weathership Station India (59°N, 19°W) in the North Atlantic Ocean. It comprises quantitative records of several zooplankton taxa— <ns3:italic>Calanus finmarchicus</ns3:italic> , <ns3:italic>Metridia lucens</ns3:italic> , <ns3:italic>Pleuromamma robusta</ns3:italic> , <ns3:italic>Oithona</ns3:italic> spp., <ns3:italic>Oncaea</ns3:italic> spp., and <ns3:italic>Acartia</ns3:italic> spp.—alongside measurements of phytoplankton abundance, temperature, salinity, chlorophyll <ns3:italic>a</ns3:italic> concentration, Secchi depth, and primary production. Sampling frequency and depth resolution varied by parameter. The dataset is organized into separate Excel files for each variable. </ns3:p>
