Results and Validation of The Ocean Circulation around Southeast Brazilian Coast - Towards Ocean Prediction for the Oil Industry

One of the main objectives of the REMO project is to forecast the ocean state and generated hydrodynamic databases for use in environmental management within the scope of oil industry activities.

Here we present some results of a 1/24° ROMS application, forced with tides, realistic wind stress and surface fluxes, and lateral boundary conditions from a global assimilated model (HYCOM/NCODA). The domain extends from 12°S to 33°S, almost covering the full extent and variability of the Brazilian Current (BC) and encompasses two of the most important regions for oil exploration, the Campos and Santos Basins.

Different metrics are used for the verification of the free-run, including: hydrographic and satellite data, historical transports of the BC, and coastal GLOSS stations for analysis of super- and sub-inertial bands. In addition, spatial charts of the phases and amplitudes of the main tidal constituents and selected transects are used to address different scale processes around the shelf and shelf-slope regions.

This application is used to generate the first REMO forecast system and datasets. The first reanalysis and operational runs of this application use an OI assimilation scheme with altimetry data and synthetic TS fields.
