Abstract:

High resolution (0.01° x 0.01°)Gulf of Mexico bathymetric grid, version 2.0 generated in February 2013. Data are in NetCDF-3 classic format. Luis Zamudio-Lopez (NRL, Luis.Zamudio@nrlssc.navy.mil) kindly offered an initial 1=100°(~1000 m) bathymetric grid for the region. This grid has been computationally modified and substantially hand edited (a) to better match the shoreline definition, (b) fill the voids in the water depths and (c) if possible, to more accurate represent the interpolated water depths. The final numerical grid conforms to the 1=25°(~4000 m) North Atlantic HYCOM computational domain, where they are both matched at 76:40 oW longitude. Data used in the development of the new grid include GSHHS: A Global Self-consistent, Hierarchical, High-resolution Shoreline Database, GEBCO 30 arc-sec global grid, a global high resolution 911x944m bathymetry (GMRT: The Global Multi-Resolution Topography) ,and the National Geophysical Data Center’s (NGDC) 6 arc-sec U.S. Coastal Relief Model database, volumes: 2, 3, 4 and 5.

Purpose:

Recent research goals for the Gulf of Mexico region (e.g., Deep-C) require the use of a more accurate and of higher resolution bathymetry. This bathymetry will be an integral part of the Gulf of Mexico Coupled Regional Modeling System (GoM-CRMS) being developed at the Center for Ocean-Atmospheric Prediction Studies (COAPS). To develop a regional 3D Earth System Model that includes interfacial exchange processes between sediment, water, and atmosphere; biogeochemical processes, the transport of organisms, and the effects of petroleum hydrocarbons on all of these processes.
