1988 - 1988 Centre for Environment, Fisheries & Aquaculture Science (Cefas) North Sea Plankton Survey - RV Corystes 04/88
As an additional aim on an unrelated survey, a series of 12 plankton tows were made on 18th July 1988 in the North Sea as part of a study of Nephrops larvae. This data consists of the numbers of larvae, along with associated positional data and volumes filtered.

This is a historic dataset and details of the exact configuration of gear used is not readily available. Details may be recorded in scientists red logbooks commonly used for surveys of this type. These are in storage at Cefas. Data storage: The raw data were stored on 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 on the database. The data tables (but not queries) have now been extracted into text files. Plankton data are normally expressed as either number of organisms per m3 or per m2. The number per m3 is obtained by dividing the numbers per sample by the volume filtered, calculated from the sampler flowmeters. Number per m2 is obtained by multiplying the number per m3 by the mean sampled depth during a deployment.
