  1. U.S. Geological Survey Woods Hole Field Center Background, Data & Visualization Matthew Arsenault USGSWoods Hole Science Center

  2. Coastal & Marine Geology Program (CMGP) Publications: usSEABED Sediment Database Current usSEABED data coverage (~340,000 data pts) and sediment mean grain size

  3. WHSC Sea Floor Mapping Geologic Mapping of the Sea Floor Integration of surficial & sub-bottom geophysical data, sediment grab, core, video, and photographic data Sidescan Sonar Seismic Reflection Swath Bathymetry Bottom Video and Photographs Samples Sediment Core and Grab Samples

  4. USGS Coastal & Marine Geology Program Why Visualization? • Just a few years ago…we were still here in “flat mapland”

  5. USGS Coastal & Marine Geology Program Why Visualization? • Just a few years ago…we were still here in “flat mapland”

  6. USGS Coastal & Marine Geology Program Why Visualization? Cognitive learning studies show that geologists & earth scientists self-select to be able to understand the relationship between 2D maps and the 3D world.
