              Count Component DateTime Description
              1 2013-11-01T00:00:00 All data obtained by NGDC were converted to a common horizontal reference frame (WGS84) using the Proj4 Cartographic Projections Library. All bathymetry data were converted to MSL using single values offsets between various tidal datums based on information obtained from the Government of Bermuda, Ministry of Environment and Planning. The topographic data were left referenced to Bermuda Ordinance Datum (OD); the offset between MSL and the OD is approximately 0.9m. It was assumed the magnitude of this difference was less than the vertical accuracy associated with the data and spatial resolution of the grids.
              1 2013-11-01T00:00:00 Datasets were visually inspected with ArcGIS, QT Modeler and MB-System for identification and editing of data anomalies, including but not limited to inconsistencies between overlapping or adjacent datasets, 'noisy' data, etc.
              1 2013-11-01T00:00:00 All data were converted to ASCII XYZ files. A 1 arc-second bathymetric 'pre-surface' grid was generated using a tensioned spline algorithm within GMT's 'surface' utility that interpolated depth values to areas where data were sparse and/or nonexistent. The bathymetric 'pre-surface' was then imported into ArcGIS and clipped to the coastline of Bermuda to remove values over land. The clipped 'pre-surface' was then converted to ASCII XYZ point data.
              1 2013-11-01T00:00:00 The final integrated 1 arc-second topo-bathy DEM was created using GMT's 'blockmedian' and 'surface' utilities. The topographic spot heights and bathymetric surface points were used as source datasets in the spline gridding algorithm.
              1 2013-11-01T00:00:00 The DEM was qualitatively evaluated to identify any artifacts that may have been introduced during the gridding process. If necessary, the data were edited and the gridding routine was re-run. Once the DEM was deemed suitable, it was compared to nautical charts to ensure data consistency.
              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.
