Censuses of nutrient salt monitoring stations in the western Mediterranean sub-region (1962 to 2010)

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.
