• Marine Aggregate Resources and Processes
  The Marine Aggregates (Sand and Gravel Assessment) Project has developed and is implementing a scientifically rigorous series of regional studies mapping the seafloor sedimentary character and assessing marine sand and gravel resources around the United States. Results of the regional assessments will ultimately comprise a national assessment of marine sand and gravel. This study is responding to increasing demand for web-accessible GIS-type data and interpreted geologic map information on the sedimentary character of the seafloor and aggregate resources suitable for beach nourishment and coastal restoration, as well as seafloor sediment texture information for benthic habitat mapping and sediment transport studies.

• Coastal Erosion of Southern Lake Michigan - USGS Fact Sheet
  Geological Survey studies the geologic processes at work in the Great Lakes region because they have direct bearing on the use, management, development, and preservation of the shoreline. It is important to understand how these processes shape our daily lives. About 15 percent of the United States' and 50 percent of Canada's population live along or near the 9,000-kilometer-long coastline of the Great Lakes. About 83 percent of the shoreline is privately-owned with property values as high as $10,000 per linear foot of lakefront.

• USGS OFR 03-120 - Bathymetry and selected perspective views of 6 reef and coastal areas in Northern Lake Michigan
  We apply state of the art laser technology and derivative imagery to map the detailed morphology and of principal lake trout spawning sites on reefs in Northern Lake Michigan and to provide a geologic interpretation. We sought to identify the presence of ideal spawning substrate: shallow, "clean" gravel/cobble substrate, adjacent to deeper water. This study is a pilot collaborative effort with the US Army Corps of Engineers SHOALS (Scanning Hydrographic Operational Airborne Lidar Survey) program. The high-definition maps are integrated with known and developing data on fisheries, as well as limited substrate sedimentologic information and underlying Paleozoic carbonate rocks.

• An Overview of Coastal Land Loss: With Emphasis on the Southeastern United States
  In states bordering the Gulf of Mexico and the Atlantic Ocean, vast areas of coastal land have been destroyed since the mid 1800s as a result of natural processes and human activities. The physical factors that have the greatest influence on coastal land loss are reductions in sediment supply, relative sea level rise, and frequent storms, whereas the most important human activities are sediment excavation, river modification, and coastal construction. As a result of these agents and activities, coastal land loss is manifested most commonly as beach/bluff erosion and coastal submergence.

• Global Inventory of Natural Gas Hydrate Occurance
  This updated global inventory reports on natural gas hydrate recovered from 20 places worldwide and includes 79 places where the presence of gas hydrate has been inferred from geophysical, geochemical, or geological evidence.

• Remote Video Monitoring
  Remote Video Monitoring (RVM) systems provide a means of automatically acquiring video data from remote locations and returning them to a central laboratory computer for processing. This project makes use of RVM technology to monitor coastal change at locations in Florida, Massachusetts, Ohio, and Washington.
