Seven years (January 2000 to December 2006) of AVHRR and SeaWiFS data were used to estimate monthly climatological means and to present SST and chlorophyll- a seasonal evolution in San Matý´as Gulf, located between 40 470 S and 42 130 S on the Argentine coast. SST and chlorophyll-a satellite maps corresponding 15 130 S on the Argentine coast. SST and chlorophyll-a satellite maps corresponding 15 seasonal evolution in San Matý´as Gulf, located between 40 470 S and 42 130 S on the Argentine coast. SST and chlorophyll-a satellite maps corresponding 150 S on the Argentine coast. SST and chlorophyll-a satellite maps corresponding 15 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 Mat´ýas Gulf. Fishing activity data gathered by a Vessel Monitoring System 20 most important resource in terms of landings and economic revenues of the San Mat´ýas Gulf. Fishing activity data gathered by a Vessel Monitoring System 20 one showed warm water and lower chlorophyll-a.

Fishing activity data gathered by a Vessel Monitoring System 2020 (2004–2006) were linked with SST and chlorophyll-a maps showing that the fishing vessels operated on the thermal front from November to March and had the maximum hake yields. In addition, AVHRR-SST- and SeaWiFS-chlorophyll-a vessels operated on the thermal front from November to March and had the maximum hake yields. In addition, AVHRR-SST- and SeaWiFS-chlorophyll-a -a maps showing that the fishing vessels operated on the thermal front from November to March and had the maximum hake yields. In addition, AVHRR-SST- and SeaWiFS-chlorophyll-aa data were compared with temperature and chlorophyll-a measured in oceano- graphic surveys carried out in 2007. graphic surveys carried out in 2007. a measured in oceano- graphic surveys carried out in 2007.
