Species distribution is provided as a layer of points representing in situ observations of organisms during submersible dives into the canyons of the Mediterranean mainland.

Selection of flow gauging stations of the French rivers (accessible via the central bank administered by the HYDRO SCHAPI) on the basis of hydrological function and monitoring stations. The data bank HYDRO stores measurements of water depth (variable time step) from 3500 stations (including 2400 which are currently in service) located on French rivers and provides access to descriptive data stations (main purpose, precise location, measurement quality, history, data available ...)

Layer of points representing the abundance weighted per canyon of observed organisms during submersible dives in the Mediterranean continental canyons.

Division of French metropolitan territories to define the zones contributing to the pollutant flow carried by rivers to the sea.

The consolidated database shows the spatial distribution of sampling effort by French and Monaco oceanographic campaigns. The measures are divided between the mouth of the Rhone, the Gulf of Lions, and Ligurian and Provence seas. The database contains 55 campaigns or time series, over 5 decades from 1962 to 2010. 28 are oceanographic campaigns of spatial strategy (some were revisited), 14 of temporal strategy, 2 of spatio-temporal strategy, and 1 one-time campaign. In total, it has 24,886 entries including: 19,027 nitrate data - 13,826 nitrite data - 11,452 ammonium data – 20,936 phosphates data – 14,605 silicates data. The majority (92%) of associated temperature and salinity data is available.

Concentrations of metals, organochlorines in surficial sediments (1st cm) in the Mediterranean coast, from RNO data.

Physico-chemical monitoring stations are part of a network under the responsibility of the water agencies. Regarding the scope of strict thematic contribution "Hydrology," the monitoring stations do not come into account because they only measure the physico-chemical quality of the rivers. These stations are used only for calculations under fluvial inputs of pollutants / nutrients.
