Total Hydrozoa abundance in the Southern Bight of the North Sea between 1971 and 1972
Inventory of Hydrozoa species for 51 stations in the Southern North Sea between January 1971 and July 1972.The data are digitized from technical reports in the frame of the 4DEMON project. Dataset on abundances of Hydrozoa species for 51 stations sampled between 23 January 1971 and 14 July 1972. Samples were taken at surface using a plankton net (opening 50 cm diameter) with varying mesh sizes. For each unique eventID the volume zooplankton (in mL) measured after sedimentation of the sample is noted.
