Abstract:

Digital Bathymetric Model (DBM) with cell size of 93 m, created through a process of merging two original DBMs: Espírito Santo Basin DBM and Campos Basin DBM. Sectors, where the original DBMs overlapped, were excluded, as well as cells with missing data (NA) and those with depth values greater than zero. The fusion of the two DBMs were performed through image blending and subsequent processing with a low-pass filter. Bathymetric data originated from 3D seismic, multibeam and sonar interferometry scanning bathymetry data produced by Brazilian Petroleum Corporation — Petrobras in Campos and Espírito Santo basins in the context of environmental studies required during various oil and gas production and drilling licensing processes. Complementary data derived from log sheets produced by the Directorate of Hydrography and Navigation – DHN (Brazilian Navy), ETOPO data obtained from the NGCD (National Geophysical Data Center) of NOAA (National Oceanic and Atmospheric Administration), SRTM (Shuttle Radar Topography Mission). Petrobras environmental data analyses (meteoceanography, geology and geomorphology, chemistry of water and sediment, and biota) are conducted by Petrobras Research and Development Center (CENPES).

DBM_Espirito_Santo-Campos_Basins * Latitude: -21.239254 * Longitude: -39.169184 * Location: Southwest Atlantic * Comment: Event coordinates refer to the center location of the area covered by the combined surveys. Data for Campos basin collected in 2004 and for Espirito Santo basin in 2006.

Comment:

This layer was made available to the iAtlantic Project (Integrated Assessment of Atlantic Marine Ecosystems in Space and Time – European Union, Grant Agreement # 818123) by Petrobras via the International Oil & Gas Producers – IOGP, an industry associate partner to iAtlantic. DBM processing and layer construction was performed at the Laboratory of Marine Applied Studies – LEMA/ EMCT (University of 'Vale do Itajaí' – UNIVALI – Brazil).
