1988 - 1988 Centre for Environment, Fisheries & Aquaculture Science (Cefas) West Central North Sea Plankton Survey - RV Cirolana 08/88

This survey was carried out as part of the International Council for the Exploration of the Sea (ICES) coordinated herring larvae survey of ICES Region IVb during the two standard sampling periods in October. The aims were to examine the drift, growth and mortality of herring larvae, as well as the vertical distribution of herring larvae in relation to water masses and movement. Plankton samples were collected at each site on the survey grid. This data consists of the numbers of larvae, along with associated positional data and volumes filtered.
