about this Topic

Geographic information systems (GIS) offer a method of integrating and visualizing geographically distributed information. More than just a map, a GIS allows one to store, reference, and display such data, greatly enhancing the ability to understand complex spatial relationships.

Data Series 436: Oblique Aerial Photography of the Arctic Coast of Alaska, Nulavik to Demarcation Point, August 7�10, 2006

Description: The Arctic Coastal Plain of northern Alaska, an area of strategic economic importance to the United States, is home to remote Native American communities and encompasses unique habitats of global significance. Coastal erosion along the Arctic coast is chronic and widespread; recent evidence suggests that erosion rates are among the highest in the world (up to ~16 m/yr) and may be accelerating. Coastal erosion adversely impacts energy-related infrastructure, natural shoreline habitats, and Native American communities. Climate change is thought to be a key component of recent environmental changes in the Arctic. Reduced sea-ice cover in the Arctic Ocean is one of the probable mechanisms responsible for increasing coastal exposure to wave attack and the resulting increase in erosion. Extended periods of permafrost melting and associated decrease in bluff cohesion and stability are another possible source of the increase in erosion. Several studies of selected areas on the Alaska coast document past shoreline positions and coastal change, but none have examined the entire North coast systematically. Results from these studies indicate high rates of coastal retreat that vary spatially along the coast. To address the need for a comprehensive and regionally consistent evaluation of shoreline change along the North coast of Alaska, the U.S. Geological Survey (USGS), as part of their Coastal and Marine Geology Program�s (CMGP) National Assessment of Shoreline Change Study, is evaluating shoreline change from Peard Bay to the United States/Canadian border, using historical maps and photography and a standardized methodology that is consistent with other shoreline-change studies along the Nation�s coastlines (for example, URL http://coastal.er.usgs.gov/shoreline-change/ (last accessed March 2, 2009). This report contains photographs collected during an aerial-reconnaissance survey conducted in support of this study. An accompanying ESRI ArcGIS shape file (and plain-text copy) indicates the position of the aircraft and time when each photograph was taken.

Digital Data Series 72: 2000 Multibeam sonar survey of Crater Lake, Oregon - Data, GIS, images, and movies

Description: In the summer of 2000, the bottom of Crater Lake, Oregon was mapped. The effort was a cooperative effort between the U.S. Geological Survey's Pacific Seafloor Mapping Project, the National Park Service, and the Center for Coastal and Ocean Mapping at the University of New Hampshire. The team used a state-of-the-art multibeam sonar system to collect high-resolution bathymetry and calibrated, co-registered acoustic backscatter to support both biological and geological research in the area (aquatic biology, geochemistry, volcanic processes, etc). This survey collected over 16 million soundings and the resulting data portrays the bottom of Crater Lake at a spatial resolution of 2 meters. This CD-ROM is published for the scientific community, the general public, and as a teaching tool. The CD-ROM contains the raw multibeam bathymetry and backscatter data as well as an ArcExplorer 2.0 project for the scientific community to use in research. Computer-generated images and a fly-by movie allow any user to visualize the lake floor. Photographs and a QuickTime� movie of the helicopter operations shows how the multibeam survey took place and a list of Crater Lake publications and related websites can be used for further Crater Lake research and general interest.

Biological Communities and Geomorphology of Patch Reefs in Biscayne National Park, Florida, U.S.A.

Description: Purpose Coral reef ecosystem management benefits from continual, quantitative assessment of the resources being managed, plus assessment of factors that affect distribution patterns of organisms in the ecosystem. In this study, we investigated the relationships among physical, benthic, and fish variables in effort to help explain the distribution patterns of ecologically and economically important species on twelve patch reefs within Biscayne National Park (BNP), Florida, U.S.A. We visited 196 randomly-located sampling stations across twelve shallow (< 10m) patch reefs, using SCUBA to conduct our surveys. We measured physical variables (e.g., substratum type), estimated the percent cover of benthic community members (e.g., coral, algae), and counted and estimated mean size for each fish species observed. We also used high-density bathymetric data collected remotely via airborne laser surveying (Experimental Advanced Airborne Research Lidar (EAARL)) to calculate rugosity (bumpiness) of the reef habitat. Here we present our findings visually by graphing our quantitative community and physical structure data simultaneously in a GIS map format. You will see that biological organisms arrange themselves on each patch reef in a non-random manner. For example, many species of fish prefer to locate themselves in areas of the reef where the rugosity index is high. Rugose parts of the reef provide them with good hiding places from predators.

Scientific Investigations Report 2007-5101: The Coral Reef of South Moloka�i, Hawai�i�Portrait of a Sediment-Threatened Fringing Reef

Description: In this landmark volume, U.S. Geological Survey researchers and their colleagues have developed and applied a remarkably integrated approach to the reefs of Moloka�i, combining geology, oceanography, and biology to provide an in-depth understanding of the processes that have made these reefs grow and that now limit them. They have joined old fashioned natural history of marine animals and plants with study of the geological evolution of the island, hydrology, meteorology, and land-use history, to an arsenal of new methods of remote sensing, including aerial photography, laser ranging, infrared thermal mapping, seismic reflection, in-situ instrumentation to measure chemical parameters of water quality, and direct measurements of the physical driving forces affecting them�such as wave energy, currents, sedimentation, and sediment transport. They provide a level of documentation and insight that has never been available for any reef before.

USGS OFR 2008-1174: Enhanced Sidescan-Sonar Imagery, North-Central Long Island Sound, Title Page

Description: Sidescan-sonar imagery from NOAA surveys H11043, H11044, and H11045 in north-central Long Island Sound were enhanced to remove tonal artifacts by matching backscatter tones in adjacent sonar lines. The enhanced imagery minimizes abrupt backscatter changes and striping, and more clearly delineates boundaries of backscatter tones and patterns."
