Altamaha River, GA (S150) Bathymetric Digital Elevation Model (30 meter resolution) Derived From Source Hydrographic Survey Soundings Collected by NOAA

Bathymetry for the Altamaha River was derived from three surveys containing 16,511 soundings. One less accurate, overlapping survey was deleted before tinning the data. The average separation between soundings was 49 meters. The three surveys used all dated from 1934. The total range of sounding data was 1.2 meters to -11.9 meters at mean low water. A mean high water value of 2.1 meters was assigned to the shoreline. One point was found that was not consistent with the surrounding data and was removed prior to tinning. DEM grid values outside the shoreline (on land) were assigned null values (-32676). The Altamaha River has five 7.5 minute DEMs and a single one degree DEM. The 1 degree DEMs were generated from the higher resolution 7.5 minute DEMs which covered the estuary. A Digital Elevation Model (DEM) contains a series of elevations ordered from south to north with the order of the columns from west to east. The DEM is formatted as one ASCII header record (A- record), followed by a series of profile records (B- records) each of which include a short B-record header followed by a series of ASCII integer elevations (typically in units of 1 centimeter) per each profile. The last physical record of the DEM is an accuracy record (C-record). The 7.5-minute DEM (30- by 30-m data spacing) is cast on the Universal Transverse Mercator (UTM) projection. It provides coverage in 7.5- by 7.5-minute blocks. Each product provides the same coverage as a standard USGS 7.5-minute quadrangle but the DEM contains over edge data. Coverage is available for many estuaries of the contiguous United States but is not complete.

Perryville and Ivanof Bay, Alaska 1/3 MHHW arc-second Coastal Digital Elevation Model

NOAA's National Geophysical Data Center (NGDC) is building high-resolution digital elevation models (DEMs) to support individual coastal States as part of the National Tsunami Hazard Mitigation Program's (NTHMP) efforts to improve community preparedness and hazard mitigation. These integrated bathymetric-topographic DEMs are used to support tsunami and coastal inundation mapping. Bathymetric, topographic, and shoreline data used in DEM compilation are obtained from
          various sources, including NGDC, the U.S. National Ocean Service (NOS), the U.S. Geological Survey (USGS), the U.S. Army Corps of Engineers (USACE), the Federal Emergency Management Agency (FEMA), and other federal, state, and local government agencies, academic institutions, and private companies. DEMs are referenced to various vertical and horizontal datums depending on the specific modeling requirements of each State. For specific datum information on each DEM, refer to the
          appropriate DEM documentation. Cell sizes also vary depending on the specification required by modelers in each State, but typically range from 8/15 arc-second (~16 meters) to 8 arc-seconds (~240 meters).

Adak, Alaska Tsunami Forecast Grids for MOST Model

The Adak, Alaska Forecast Model Grids provides bathymetric data strictly for tsunami inundation modeling with the Method of Splitting Tsunami (MOST) model. MOST is a suite of numerical simulation codes capable of simulating three processes of tsunami evolution: generation, transoceanic propagation, and inundation of dry land. Tsunami waves are computationally propagated across a set of three nested grids (A, B, and C), each of which is successively finer in resolution, moving from offshore to onshore. Nearshore details are resolved to the point that model output can be directly compared with tide gauge observations and can provide estimates of wave arrival time, wave amplitude and simulation of wave inundation onto dry land. A Grid Resolution: 60 arc-sec, 90 arc-sec in x direction. 90 arc-sec, 105 arc-sec in y direction. B Grid Resolution: 13.3333 arc-sec in the x direction. 12 arc-sec, 20 arc-sec in the y direction. C Grid Resolution: 2 arc-sec in the x direction. 3 arc-sec, 4 arc-sec in the y direction.

Long Island Sound, NY/CT (M040) Bathymetric Digital Elevation Model (30 meter resolution) Derived From Source Hydrographic Survey Soundings Collected by NOAA

Bathymetry for Long Island Sound was derived from fifty-five surveys containing 562,596 soundings. Twenty-four older, less accurate, overlapping surveys were entirely omitted, and the overlap from eight older, less accurate surveys was omitted before tinning the data. The average separation between soundings was 77 meters. The fifty-five surveys used dated from 1931 to 1990. Approximately 40 percent of the surveys were from 1931 to 1939. The total range of sounding data was 2.1 meters to - 113.4 meters at mean low water. Mean high water values between 0.6 and 2.3 meters were assigned to the shoreline. Eighty-eight points were found that were not consistent with the surrounding data. These were removed prior to tinning. DEM grid values outside the shoreline (on land) were assigned null values (-32676). Long Island Sound has fifty-one 7.5 minute DEMs and five one degree DEMs. The 1 degree DEMs were generated from the higher resolution 7.5 minute DEMs which covered the estuary. A Digital Elevation Model (DEM) contains a series of elevations ordered from south to north with the order of the columns from west to east. The DEM is formatted as one ASCII header record (A- record), followed by a series of profile records (B- records) each of which include a short B-record header followed by a series of ASCII integer elevations (typically in units of 1 centimeter) per each profile. The last physical record of the DEM is an accuracy record (C-record). The 7.5-minute DEM (30- by 30-m data spacing) is cast on the Universal Transverse Mercator (UTM) projection.

Worldwide Database of Analog Marine Seismics, Bathymetry, Magnetics, and Gravity Data

The Analog Marine Geophysical Underway data file consists primarily of seismic data and some bathymetry, magnetics, and gravity data. Most of the data are released to NGDC in microform packages; microfilm, microfiche exceptions include deep penetration seismic record sections and maps released in full or half scale. The data cover approximately 5 million miles of worldwide oceans and have been collected by various academic institutions, government agencies and foreign governments. Data are quality checked, master and backup copies produced and disseminated upon request. These seismic data include Lease Sale (LS) data which are a collection of marine geophysical data in a particular area and common depth point (CDP) data consisting of multichannel high-resolution underway seismic records. Shot-point navigation and occasionally annotated bathymetry accompany the seismic data. The data were released mainly from the US Geological Survey (USGS), and the Minerals Management Service (MMS). Output Media: sections, maps, 35-mm microfilm, magnetic tapes, text and microfiche. In most cases, the microfilm has been scanned and data available as tiff images.

U.S. Gravity Data per 2 min Cell (96)

This 2' gravity density grid for the conterminous United States displays the distribution of the about 1.8 million terrestrial and marine gravity data held in the National Geodetic Survey gravity data base in July 1996. These data were augmented by gravity data contributions from NGA (former National Imagery and Mapping Agency (former Defence Mapping Agency)) and by satellite altimeter-derived marine gravity anomalies computed by Sandwell and Smith (1996). The values show the number of gravity data contained in a given 2' cell. Additional information is available at http://www.ngs.noaa.gov/GEOID/geoid.htmlWe are particularly grateful to NGA (former National Imagery and Mapping Agency) for their assistance and their data contributions.
