Physical environment - In situ data - Mean fluorescence collected during the REISE2 survey in May 1995
Three environmental parameters were measured in situ during the REISE2 survey in April 1995. Temperature and salinity were measured using a probe. Fluorescence (mean for the water column) was measured using a fluorometer. This survey gives illustration of spring conditions.

- Généralités sur la provenance
- In 1995, two “REISE” surveys were held: these surveys looked at ichthyoplankton between the Schelde and Seine estuaries. There were 60 stations sampled in May 1995 (REISE 2). Ichthyoplankton was collected with a double-framed bongo net (plankton nets with 500 μm mesh). Oblique tows were carried out at 2 knots from the surface to the proximity of the seabed.
- Description
- Statistical analysis : the statistical distribution of environmental data were tested for normality (histograms, skewness, kurtosis). The data were transformed whem skewness value exceeded |1| and/or kurtosis exceeded 1 and if a normalising function that could improve the data distribution was found. Environmental variables were measured on scales based on analytical conventions that are unrelated to the natural processes generated them. Therefore, any transformed scale is as appropriate as those on which these data were originally recorded. Geostatistical interpolation : the spatial variation of environmental 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 environmental data studied in CHARM's area. For legends of maps, approximates od the 5th and the 95th quantiles were used for the minimales and maximales values respectively.
