1. Department of the Interior uses NOAA Hydrographic Services data, products and services Susan Russell-Robinson Acting Program Coordinator, USGS Coastal and Marine Geology Program September 17, 2015

2. Listing of charts, data sets and models 1. Multibeam and single-beam bathymetry soundings - used to build bathy grids (50- to 1000-m resolution) in study areas where gridded data is not available http://maps.ngdc.noaa.gov/viewers/bathymetry/http://maps.ngdc.noaa.gov/viewers/bathymetry/ 2. Tsunami inundation maps - NOAA gridded data (30m and finer resolution) in coastal areas that combine bathymetry and topography https://www.ngdc.noaa.gov/mgg/inundation/tsunami/inund ation.htmlhttps://www.ngdc.noaa.gov/mgg/inundation/tsunami/inund ation.html 3. Coastal Relief Model - NOAA gridded data (~100-m resolution) 4. Southern Alaska Relief Model - ~1000m resolution, assembled by NOAA for Law of the Sea collaboration https://www.ngdc.noaa.gov/mgg/coastal/s_alaska.htmlhttps://www.ngdc.noaa.gov/mgg/coastal/s_alaska.html 5. Custom grid extraction - get custom (user chooses extent and resolution) grids built from NOAA database holdings http://maps.ngdc.noaa.gov/viewers/wcs-client/http://maps.ngdc.noaa.gov/viewers/wcs-client/ 6. Global bathy-topo data - all-purpose 2-km resolution data handy for basemaps https://www.ngdc.noaa.gov/mgg/global/global.htmlhttps://www.ngdc.noaa.gov/mgg/global/global.html 7. High-resolution coastline - https://www.ngdc.noaa.gov/mgg/shorelines/gshhs.htmlhttps://www.ngdc.noaa.gov/mgg/shorelines/gshhs.html 8. NOAA digital charts - derived from hydrographic data, useful as basemaps http://www.charts.noaa.gov/InteractiveCatalog/nrnc.shtmlhttp://www.charts.noaa.gov/InteractiveCatalog/nrnc.shtml Dozens of USGS and BOEM scientists responded to request for examples of information they use. Each one had a list of 5 or 8 or 10 different products and sources … and many applications.

3. Use of NOAA Hydrographic Survey Data for Numerical Modeling Hindcast and forecast beach and nearshore evolution to increase understanding of coastal processes and guide restoration efforts. Characterize coastal vulnerability to storms. Identify transport patterns to inform clean-up of Deepwater Horizon “sinking tarballs.” Characterize sea floor stress and sediment mobility to understand seafloor evolution processes, delineate habitat, and inform anthropogenic use. Investigate long-term bathymetric change.

4. For post Hurricane Sandy projects First regional bathymetry map First regional back scatter mosaic of Delmarva inner continental shelf

5. Another Atlantic example: BOEM use of NOAA Hydrographic Data From: Regional Geophysical Survey and Interpretive Report for the Virginia Wind Energy Area offshore Southeastern Virginia

6. California Seafloor Mapping Program https://walrus.wr.usgs.gov/mapping/csmp/sheets.html Success of the products produced with the State of California characterizing state waters relied upon the use of high-resolution bathymetric data. Existing data from NOAA Hydrographic Services met some of the data standard requirements. Data collection was conducted by USGS, CSUMB Seafloor Mapping Lab and Fugro on contract to NOAA. CA Ocean Protection Council provided financial support to merge these data. Recently compiled and merged lidar data has been made available through NOAA’s Digital Atlas web site.

7. Progression of submarine landslide, Port Valdez, Alaska Analysis of landslide associated with 1964 Great Alaska Earthquake Caption: (A) A hydrographic survey conducted in 1957 gives the approximate pre- earthquake shape of the fjord margin near Valdez old town and the location of the slope edge. (B) Multibeam bathymetry data show the post-landslide configuration, with parts of the slope edge recessed ~150 m east of the pre-earthquake location, mostly south of Valdez old town (labeled ‘Failed margin’). Cross sections A-A’ and B-B’ show differences between the two surveys where the margin is largely unchanged, and where significant submarine landsliding took place, respectively.

A CHARACTERIZATION OF THE CORAL AND SPONGE COMMUNITY ON PIGGY BANK SEAMOUNT IN SOUTHERN CALIFORNIA FROM A SURVEY USING A REMOTELY OPERATED VEHICLE http://data.nodc.noaa.gov/coris/library/NOAA/CRCP/other/other_crcp_publications/DeepSeaCoralRT/Site-char-report- 2010-Piggy-Bank.pdf Hydrographic Services uses USGS and BOEM data and products NOAA Deep-Sea Coral Research and Technology Program

9. Future Needs Future Benefits A priority for the USGS and for DOI land and resource managers is having high-resolution documentation of coastal change from hurricanes, extreme storms, slumping, landslides and, in specific regions, isostatic rebound. This will require: – Improved seamless topographic-bathymetric data, delivered to a common set of high-resolution standards – Increased coordination of data collection by Federal agencies with interlinked missions, to best leverage limited resources and avoid duplication – Increased frequency of data collection, as appropriate, to capture landscape and seafloor change – Anticipation of new technology and methods to collect data for modeling “Prepare the Nation for impacts of climate change.”
