Resumo Imagens ópticas e no infravermelho-próximo adquiridas por sensores remotos em condição de reflexão especular bidirecional entre o sol, a superfície do mar e o sensor (condição de sunglint) podem ser utilizadas para identificar filmes, feições, processos oceanográficos e meteorológicos atuantes sobre a superfície marinha. Imagens do sensor or...

Time series of ocean data products were analyzed to describe the average pattern and time variability in the Santos Basin, located in Southeast Brazil, Southwestern-South Atlantic. Considering the deposits in the Pre-Salt, Santos Basin is becoming more important due to discoveries of huge volumes of light oil and natural gas. Sea surface temperatur...

Time series of satellite-derived sea surface chlorophyll concentration (SSC) from 2002 to 2012 were used to investigate the phenology of phytoplankton bloom in the Sergipe-Alagoas Basin, located in Northeast Brazil, Western Tropical Atlantic. The seasonal phytoplankton cycle is the dominant mode of temporal variability. The use of a Gaussian functi...

Global monitoring of marine surfactants is important for understanding the heat, particle, momentum, and gas exchanges between the ocean and atmosphere. Observing the sunglint, i.e., the specular reflection between Sun, sea surface, and sensor, which intensity depends on the geometry of acquisition, has the potential to improve surfactants detectio...

This study aimed at understanding the relation between C. hippurus fisheries and the marine environment through the analysis of landing data and the oceanographic variables of sea surface winds, sea surface temperature, chlorophyll concentration and bathymetry, using tools of Geographic Information System. A Potential fishing Map with areas of high...
