Optimisation de la surveillance des masses d’eau DCE en Méditerranée. Utilisation de produits dérivés d’images satellites en complément du réseau de mesures in-situ
Provedor de dados: 5
Autores: Ganzin, Nicolas; Mangin, Antoine.
This study aims at showing the potential of « water colour » data derived from satellite imagery to optimise the monitoring of coastal waters within the WFD, with the French Mediterranean as a study area. The work is focused on one specific parameter, the surface chlorophyll-A (chl-a) concentration of which a monthly atlas for reference to “normal” values is provided, which consists of : (i) the monthly chl-a median computed from satellite data of 2003, 2004 and 2005 ; (ii) the integration in space of these values, represented by their average over the WFD water masses (except those of very small size) ; (iii) an indicator of the spatial variability of the chl-a through the spatial standard deviation within each water mass. Another important result is the...

Indicadores del estado del ambiente marino patagónico en áreas frontales
Provedor de dados: 20
Autores: Carranza, M.
En este trabajo se caracterizan las regiones frontales altamente productivas del Mar Patagónico empleando datos de clorofila satelital (CSAT) derivada del Sea-viewing Wide Field-of-view Sensor (SeaWiFS) durante el período 1998-2006. A partir de estos datos se identifican cuatro áreas de máxima concentración de clorofila: el Frente del Talud, el Frente de la Plataforma Media, el Frente de Patagonia Austral y el Frente de Valdés. Los tres primeros se definen por regiones de amplitud media de CSAT &gt; 3.5 mg/m3, mientras que el último se define por la región de CSAT media de verano &gt; 2 mg/m3. Sobre estas regiones se elaboran indicadores de clorofila (CSAT), temperatura superficial del mar (SST) y viento en superficie. La temperatura es derivada del...
