Port Alexander, Alaska Tsunami Forecast Grids for MOST Model

The Port Alexander, 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: 90 arc-sec. B Grid Resolution: 18 arc-sec. C Grid Resolution: 1 arc-sec in the x direction. 1.5 arc-sec in the y direction.

St. Marys River/Cumberland Sound, GA/FL (S170) Bathymetric Digital Elevation Model (30 meter resolution) Derived From Source Hydrographic Survey Soundings Collected by NOAA

Bathymetry for St. Marys River/Cumberland Sound was derived from six surveys containing 36,976 soundings. Five older, overlapping, less accurate surveys were omitted before tinning the data. The average separation between soundings was 42 meters. The six surveys used dated from 1934 and 1935. The total range of sounding data was 1.2 meters to -20.7 meters at mean low water. Mean high water values between 1.8 and 2.1 meters were assigned to the shoreline. Five points were found that were not consistent with the surrounding points. These were removed prior to tinning. DEM grid values outside the shoreline (on land) were assigned null values (-32676). St. Marys River/Cumberland Sound 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.

2-minute Gridded Global Relief Data (ETOPO2) v2

This version has been superseded by a newer version. It is highly recommended for users to access the current version. Users should only access this superseded version for special cases, such as reproducing studies. Two-minute gridded global relief for both ocean and land areas are available in the ETOPO2v2 (2006) database. ETOPO2v2 replaced ETOPO2 (2001). The historic 2-minute (ETOPO2v2) and 5-minute (ETOPO5) data are deprecated, but still available.

New Jersey Inland Bays, NJ (M080) Bathymetric Digital Elevation Model (30 meter resolution) Derived From Source Hydrographic Survey Soundings Collected by NOAA

Bathymetry for the New Jersey Inland Bays was derived from nineteen surveys containing 127,502 soundings. Four older, overlapping, less accurate surveys were omitted before tinning the data. The average separation between soundings was 45 meters. Eighteen of the nineteen surveys used dated from 1935 to 1940. The remaining survey, located in the southwest, dated from 1972. The total range of sounding data was 1.2 to -16.2 meters at mean low water. Mean high water values between 0.6 and 1.3 meters were assigned to the shoreline. Six 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). The New Jersey Inland Bays have seventeen 7.5 minute DEMs and two 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. 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.

American Samoa: Continuously Updated Digital Elevation Model (CUDEM) - 1/9 Arc-Second Resolution Bathymetric-Topographic Tiles

NOAA's National Centers for Environmental Information (NCEI) is developing a suite of digital elevation models (DEMs) for the U.S. coast to support a variety of NOAA missions, including improved inundation modeling and mapping, habitat characterization, and visualization of Earth's surface. The DEMs are being developed according to a 0.25 degree tiling scheme. The spatial resolution of the tiles "telescopes" from the coastal zone to the deep ocean floor at 1/9, 1/3, and 3 arc-second grid resolution. Only the 1/9 arc-second DEM tiles integrate both bathymetric and topographic data; all other resolutions map bathymetry only. The tiling of the DEMs facilitates targeted, rapid updates as new coastal and marine elevation data are acquired and become available. Bathymetric and topographic data utilized for DEM creation originate from a variety of sources, including (but not limited to) the NOAA Office of Coast Survey, NOAA National Geodetic Survey, NOAA Office for Coastal Management, U.S. Geological Survey, and the U.S. Army Corps of Engineers. The DEMs are referenced vertically to American Samoa Vertical Datum of 2002 height (m) . The vertical units of the DEMs are meters. The DEMs are referenced horizontally to NAD 83. The horizontal units of the data are decimal degrees.

Seldovia, Alaska 8/15 arc-second Coastal Digital Elevation Model

NOAA's National Centers for Environmental Information (NCEI) 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).
