Abstract:

The Bathymetric Dynamic Digital Elevation Model (BDDEM) was developed using open source software. The BDDEM's initial basis was obtained by merging the five digital elevation models of the Northern Gulf region released by the National Centers for Environmental Information. The final build of the BDDEM includes all of the National Ocean Service hydrographic surveys conducted in Alabama, Mississippi and Louisiana through 2011. The digital elevation model (BDDEM) is available at resolutions of 3, 1 and 1/3 arc seconds.

Purpose:

The Bathymetric Dynamic Digital Elevation Model has been used to support CONCORDE's four-dimensional biogeochemical / lower trophic level synthesis model encompassing Mississippi Sound and Mississippi Bight.

Data Parameters and Units:

Bathymetry (m)

Instruments:

Single beam echo sounder, multibeam echo sounder

Provenance and Historical References:

Volume 4 of the Coastal Relief Model (CRM) (released in 2001), provided the bathymetric basis for the BDDEM. Five digital elevation models (Northern Gulf Coast, New Orleans, Biloxi, Mobile and Southern Louisiana) produced by the National Centers for Environmental Information was also incorporated into the BDDEM. The final stage of the BDDEM development include the ingestion of the National Ocean Service hydrographic surveys conducted in Alabama, Mississippi and Louisiana. The historical data can be obtained from the National Centers for Environmental Information's data repository.
