Count Component Title Abstract
1 Mariana Trench 6 arc-second Bathymetric Digital Elevation Model NOAA's National Geophysical Data Center (NGDC) created a bathymetric digital elevation model (DEM) for the Mariana Trench and adjacent seafloor in the Western Pacific Ocean. Bathymetric data used in DEM compilation were obtained from various sources, including internation, federal and academic partners. The DEM is referenced to the horizontal datum of World Geodetic System 1984 (WGS 84) and the vertical datum of sea level. Grid spacings for the Mariana Trench DEM is 6 arc-seconds (~180 meters). Please note that while positive elevations (elevations greater than 0 meters) are present in the DEM over 'dry' land (i.e. islands such as Guam and the Northern Mariana Islands), they should be ignored as the focus of DEM development was solely in the bathymetric realm.

            1 2012-12-15T00:00:00 All datasets obtained by NGDC were converted to a common ASCII XYZ file format. All data obtained were natively referenced to WGS84. No vertical datum transformations were performed, as any vertical datum offsets between datasets are assumed to be less than vertical accuracy associated with 6 arc-second grid, and are thus effectively equivalent.
            1 2012-12-15T00:00:00 The data were visually inspected with Fledermaus and ArcGIS for identification and editing of data anomalies. Datasets were compared with overlapping datasets to ensure data consistency. In some cases, overlapping data were edited to ensure a smooth transition between adjacent datasets.
            1 2012-12-15T00:00:00 ASCII 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. Preferential weighting was given to more recent, higher-accuracy datasets.
            1 2012-12-15T00:00:00 The DEM was reviewed qualitatively for any noticeable artifacts introduced during the gridding process using imagery and other ancillary data. If necessary, problematic source data were edited and the an updated grid was created.
            1 2015-04-22T00:00:00 NOAA created the National Centers for Environmental Information (NCEI) by merging NOAA's National Climatic Data Center (NCDC), National Geophysical Data Center (NGDC), and National Oceanographic Data Center (NODC), including the National Coastal Data Development Center (NCDDC), per the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235. NCEI launched publicly on April 22, 2015.
