Abstract

Time-space variations of fitoplancton clorophile pigments density at the North Western Caribbean, the Loop Stream, the Florida Strait and the East of the Florida's Penninsula is studied through the digital processing of images from the Coastal Zone Color Scanner (CZCS) onboard the Nimbus 7 satellite and related to oceanographic processes in the region between years 1978 and 1986. A differentiation was observed among the sampled stations in mean and maximum values as well as their ranges of variation. A marked seasonality was detected in pigment density in the sampled stations with average values of 0.072 mg/m3 in summer and 0.115 mg/m3 in winter.
