Abstract

The dynamic regionalization of the island of Santo Domingo was determined with satellite reflectance derived from MODIS-Aqua sensor. To determine the temporal variability seasonal scenarios (not hurricane season and hurricane season) were established. Daily images were used from June 2002 to November 2013. To define the dynamic regions empirical orthogonal function first standardized (SEOF1) that guarantees the best combination of numerical variables Rrs412 nm satellite reflectances and Rrs488 nm was used. On the island of Santo Domingo 24 dynamic regions were identified in 2 domains Atlantic and Caribbean. In the domain of the Atlantic were identified 1 oceanic province with 2 dymanic regions, 1 coastal province and 2 coastal subprovince in which 8 dynamic regions were distributed, 1 coastal province and 2 coastal subprovince in which 8 dynamic regions were distributed. In the domain of the Caribbean were identified 1 oceanic province with1 dynamic region, 4 coastal province and 3 coastal subprovinces in which 13 dynamic regions were distributed. Based on the concentration of chlorophyll-a (Chla) Satellite average 7 regions were classified as oligotrophic, 5 as mesotrophic, and 12 eutrophic distributed in the Atlantic and Caribbean domains. The study of the temporal variability showed that the spatial dimension of the dynamic regions is modulated by the seasonal influence of each proposed scenario. The dynamic regionalization of the island of Santo Domingo allowed to identify surface mesoscale oceanographic structures as eddies and filaments for the month of February 2005.
