Title

1996 - 1997 Centre for Environment, Fisheries & Aquaculture Science (Cefas) Joint Nutrient Study (Jonus) II Plankton Survey

Abstract

The Jonus II programme was run to examine impacts of nutrients on the coastal pelagic community and consisted of a series of 7 individual cruises using RV Cirolana and the charter vessel Lough Voyager. The survey was conducted in the southern North Sea, the Thames Estuary, The Wash, the Irish and Celtic Sea, the South-Western Approaches and the western English Channel. As part of the survey aims phytoplankton and zooplankton samples were collected. This data consists of the numbers of microzooplankton, along with associated positional data and volumes filtered.

Quality and validity

Lineage

Samples were collected using a ring net with a 50 cm diameter opening, and an unencased high speed plankton sampler with a 270 um mesh 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 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.
