1989 - 1989 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Southern North Sea And English Channel Plankton Survey - RV Corystes 02/89
A survey carried out in the Southern North Sea and English Channel by the Centre for Environment, Fisheries and Aquaculture Science. On 5th February a small (10 stations) herring larvae survey was undertaken using the MkII MAFF 53cm plankton sampler. This data consists of the numbers of herring larvae, along with associated positional data and volumes filtered.

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.
