The SAR-derived wind fields presented the detailed structure of wind fields along the coastal areas, which had heretofore been unobtainable from scatterometer observation. Comparison of the retrieved SAR wind speeds with in-situ buoy wind measurements showed a small difference of less than 1 m/s, which implied that the results of SAR wind retrieval satisfied the limit of accuracy of satellite scatterometry...
The Cabo Frio zone presents an important coastal-oceanic system of great interest for biological and economical ressources. Among others, the coastal upwelling is one of the specific feature that occurs frequently in the area. As presented in a previous feasibility study, the main parameters of the upwelling can be tracked by acoustic tomography in vertical slices, using a feature model parameterization...
The Cabo Frio region (Brazil) presents a unique coastal-oceanic system. Among several interesting oceanic phenomena that occur in this region, the coastal upwelling is the most important coastal feature and is mainly forced by persistent winds northeast. An oceanic feature model which specifically describes the Cabo Frio upwelling process is used as a parameterization scheme to track the time evolution...
The study of the ocean circulation is the central core of all dynamical oceanography. The routine derivation of sea surface temperature or infrared brightness temperatures has been used to estimate the surface circulation by calculating the motion of the thermal features (coastal upwellings, filaments and eddies) in successive images. To that respect, a number of authors have developed different methodologies...
This paper describes the implementation of a prototype operational system for providing near-real-time information on the ocean water property and circulation environment in the Gulf of Mexico (GOM)/Georges Bank (GB) region. This application of the Harvard Ocean Prediction System (HOPS) model to the Advanced Fisheries Management Information System (AFMIS) was developed and tested during a 52-week...
Since the 1980s, corals have experienced unprecedented high temperature-induced coral bleaching and subsequent mortality. Location, intensity, severity, duration, and recovery from bleaching are predictable by the satellite sea surface temperature (SST) "HotSpot" method (Goreau&Hayes, 1994). HotSpot patterns have been mapped over the last 2 decades, and show strong regional trends: SST...
