Resumen:
Seven years (January 2000 to December 2006) of AVHRR and SeaWiFS data were used to estimatemonthly climatologicalmeans and to present SST and chlorophyll-a seasonal evolution in San Matías Gulf, located between 40 470 S and 42 130 Son the Argentine coast. SST and chlorophyll-a satellite maps corresponding to spring–- summer showed two well differentiable sectors: the southern zone presented colder waters and higher chlorophyll-a concentration while the northern one showed warm water and lower chlorophyll-a. Hake (Merluccius hubbsi) is the most important resource in terms of landings and economic revenues of the San Matías Gulf. Fishing activity data gathered by a Vessel Monitoring System (2004–2006) were linked with SST and chlorophyll-a maps showing that the fishing vessels operated on the thermal front fromNovember toMarch and had themaximumhake yields. In addition, AVHRR-SST and SeaWiFS-chlorophyll-a data were compared with temperature and chlorophyll-a measured in oceanographic surveys carried out in 2007.
