Physical environment - In situ data - Mean bottom salinity, standard deviation, kriging error during Channel Ground Fish Survey (CGFS) from 1997 to 2006

Type: datasetLicense: not specifiedCategory: environmentScale: 1 / 2500Last update: unknown
Oceanographic geographical features

Temperature and salinity were measured in situ at sea surface and at bottom during the CGFS surveys from 1997 to 2006. Temperature and salinity were measured using a probe. These surveys give illustration of autumn conditions. Average, standard deviation and interpolation error of yearly maps were produced

Data origin:

The survey extends from the Eastern English Channel to the south of the North Sea, which corresponds to ICES divisions VIId and IVc. The study area is divided into rectangles of 15’ latitude and 15’ longitude using a systematic sampling strategy. The sampling gear is a high opening bottom trawl well adapted for catching demersal species. Since 1997, temperature and salinity (surface and bottom) are measured using a probe attached on the headrope of the trawl.
