DETECTION OF SMALL-SCALE COASTAL OCEANOGRAPHIC PROCESSES THROUGH LANDSAT-TM/ETM+ IMAGES: IMPLICATIONS FOR THE STUDY OF BIOLOGICAL PROCESSES ALONG THE PATAGONIAN COASTS OF ARGENTINA

The Argentine coastal zone, with its highly productive coastal waters, allows the existence of important seabird and marine mammal breeding assemblages, fish and crustacean spawning and nursery areas, and extensive macroalgae and mollusk beds. Knowledge of factors determining the dynamics of coastal...
