1989 - 1989 Centre for Environment, Fisheries & Aquaculture Science (Cefas) North Sea Plankton Survey - RV Corystes 11/89
This survey was carried out between 4th Oct-6th Nov 1989 in the North Sea. Its aim was to carry out plankton sampling for herring larvae. Plankton samples were collected at each site on a planned survey grid. This data consists of the numbers of herring larvae, along with associated positional data and volumes filtered.

Sampling was carried out using the Longhurst-Hardy Plankton Recorder and a High-Speed towed plankton net. Data Storage: The raw data were stored in an Access database. The various data files were stored on the database in a series of tables linked by having the content of certain fields in common. All routine calculations, calibration changes and conversions were carried out in the database. The data tables (but not queries) have now been extracted into comma separated variable files. Plankton data are normally expressed as either number of organisms per m3 or per m2. These are calculated from the volume of water filtered (derived using regression co-efficients calculated for different flowmeters). Number per m3 is obtained by dividing the numbers per sample by the volume filtered, and number per m2 of sea surface is obtained by multiplying the number per m3 by the mean total or sampled depth during a deployment.
