Native Dataset Environment: Microsoft Windows 2000 Version 5.2 (Build 3790) Service Pack 2 ESRI ArcCatalog 9. T00:00:00 - The DEM was quantitatively evaluated by comparing with source datasets.Preferential weighting was given to more recent, higher-accuracy datasets. T00:00:00 - xyz files for each input dataset were gridded using MB-System's 'mbgrid' tool, which utilizes a high-tension spline interpolation method to fill grid cells with no input elevation values.The resulting Arc ASCII grid was imported into ArcGIS and clipped to the coastline to remove values over land. Points extracted every 5 meters along the coastline were also included to ensure that the bathymetric grid reached zero at the coast. T00:00:00 - xyz files of the bathymetric data were surfaced using GMT's 'surface' tool onto a 1/3 arc-second grid that interpolated to fill empty cells.Datasets were then compared with overlapping datasets to ensure data consistency. T00:00:00 - Datasets were visually inspected with ArcGIS for identification and editing of data anomalies.They were also converted to common file format for visualization and inspection. T00:00:00 - All datasets obtained by NGDC were converted to common horizontal and vertical datums of WGS 84 geographic and NAVD 88, respectively, using VDatum.NOAA National Centers for Environmental Information.ICSU-WDS > International Council for Science - World Data System.Global Change Master Directory (GCMD) Project Keywords Ocean > Atlantic Ocean > North Atlantic Ocean > Gulf of Mexico.Global Change Master Directory (GCMD) Location Keywords DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S.DOC/NOAA/NESDIS/NCEI > National Centers for Environmental Information, NESDIS, NOAA, U.S.Global Change Master Directory (GCMD) Data Center Keywords DATA ANALYSIS AND VISUALIZATION > GEOGRAPHIC INFORMATION SYSTEMS > WEB-BASED GEOGRAPHIC INFORMATION SYSTEMS.Global Change Master Directory (GCMD) Service Keywords DATA ANALYSIS AND VISUALIZATION > VISUALIZATION/IMAGE PROCESSING.DATA MANAGEMENT/DATA HANDLING > DATA SEARCH AND RETRIEVAL.1 meter - GEOGRAPHIC INFORMATION SYSTEMS > WEB-BASED GEOGRAPHIC INFORMATION SYSTEMS.
