Observations and modeling

Refine data and measurements in priority areas

This task is being carried out by IFREMER, BRGM and extra-community partners (University of the West Indies Trinidad & Tobago, CARICOOS, MonaGis) and will refine the data in the priority measurement areas, duration and key parameters to be observed.

Measurement campaigns are planned in the French Antilles and in the islands of Extra- European partners.

Creation of a hydrodynamic modeling platform

A hydrodynamic modelling platform will be created to improve the knowledge of the 3D circulation of water masses in the region by detailing the role of eddy structures (< 30 km) in the control of hydrological properties in the vicinity of Caribbean islands taking into account the impact of extreme events such as hurricanes.

 This work will be carried out using numerical modelling according to :

Two spatial scales of work: The Caribbean Sea and the French West Indies (Guadeloupe and Martinique);
Two time scales, reanalysis for the period 1980-2010 and projection for the period 2070-2100 to take into account the effects of climate change.
