Validated and aggregated data from current profilers measured continuously by hull-mounted ADCPs (Acoustic Doppler Current Profiler).

Under the EU Water Framework Directive (2000/60/EC), among the biological parameters involved in the assessment of coastal water bodies, the quality element "phytoplankton" is defined. This indicator Phytoplankton is made up of several indexes including a biomass index and an abundance index. Oxygen balance appearing among the elements of physicochemical quality selected for the classification of the ecological state of coastal water bodies. The quality element "benthic invertebrates" is also part of the biological parameters involved in the assessment of these water bodies.

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.

La carte présente la distribution de Vibrio nigripulchritudo MP (Moyennement Pathogène) sur les fermes d'élevage de crevette L. Stylirostris de Nouvelle-Calédonie. Ces vibrios ont été isolés par multiplex PCR suite à des épisodes de mortalités signalés au réseau d'épidémio-vigilance de la filière aquacole de Nouvelle-Calédonie.
