Physical environment - In situ data - Surface salinity collected during the International Bottom Trawl Survey in summer (1991-2009)

Temperature and salinity were measured, in situ at sea surface and at bottom during the iBTS surveys from 1991 to 2009 . Temperature and salinity were measured using CTD probe. The IBTS Q3 survey gives a good illustration of summer conditions.

Statement
The data was extracted by year and quarter from the ICES oceanographic database.
Description
Geostatistical interpolation : the spatial variation of data were analysed using GENSTAT (GENSTAT 7 Committee, 2004), which is a GENeral STATistics package including the main geostatistical tools. It computes experimentala variograms, fits these with various authorised mathematical models and uses them to calculate kriged estimates on a fine regular grid (of latitudes and longitudes). The grid of points was imported into ArcMap and interpolated with the Spatial Analyst extension in order to create a continuous raster of 1 km² resolution. The resulting maps illustrate the spatial distributions and the variations over time for variables studied in CHARM's area. For legends of maps, approximates of the 5th and the 95th quantiles were used for the minimales and maximales values respectively. Average and standard deviation maps were computed based on all interpolated maps over all the period studied
