Research Project
National Assessment of Shoreline Change Project
Description: Beach erosion is a chronic problem along most open-ocean shores of the United States. As coastal populations continue to grow, and community infrastructures are threatened by erosion, there is increased demand for accurate information regarding past and present shoreline changes. There is also need for a comprehensive analysis of shoreline movement that is regionally consistent. To meet these national needs, the Coastal and Marine Geology Program of the U.S. Geological Survey (USGS) is conducting an analysis of historical shoreline changes along open-ocean sandy shores of the conterminous United States and parts of Alaska and Hawaii. A primary goal of this work is to develop standardized methods for mapping and analyzing shoreline movement so that internally consistent updates can periodically be made to record shoreline erosion and accretion.

Research Project
National Assessment of Coastal Change Hazards
Description: The National Assessment of Coastal Change Hazards is a multi-year undertaking to identify and quantify the vulnerability of U.S. shorelines to coastal change hazards such as the effects of severe storms, sea-level rise, and shoreline erosion and retreat. It will continue to improve our understanding of processes that control these hazards, and will allow researchers to determine the probability of coastal change locally, regionally, and nationally. The Assessment will deliver these data and assessment findings about coastal vulnerability to coastal managers, other researchers, and the general public.

Research Project
Marine Aggregate Resources and Processes
Description: 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.

Evolution and History of Incised Valleys: The Mobile Bay Model - USGS Fact Sheet
Description: Incised valleys along the Gulf coast commonly result from rivers eroding rapidly in response to a fall in sea level. As sea level rises, sediments fill incised valleys and form nearshore elongated sandbodies such as barrier islands. These sandbodies can be potential sites for hard-mineral accumulations and are modern analogues to buried sands in the ancient rock record with high potential of being oil and gas reservoirs. Processes that formed residual sediment accumulations may also help to predict the outcome of man's erosion mitigation and wetland nourishment efforts. Today, the geologic imprint of incised valleys across the continental shelf provides evidence of sea-level change over the past 18,000 years.

Hurricane Impacts on the Coastal Environment - USGS Fact Sheet
Description: In terms of insured losses, Hurricane Andrew is the most severe catastrophe in the Nation history. Prior to the arrival of Andrew, the U.S. Geological Survey (USGS), in cooperation with the Louisiana Geological Survey (LGS), acquired an extensive body of information and data on the behavior and long-term erosion of Louisiana barrier islands. As a result, we have a clear understanding of pre-storm conditions in this area; Andrew provided an opportunity to learn in detail the impact of a very large storm on Louisiana coastal environment.

The Lake Pontchartrain Basin: Louisiana's Troubled Urban Estuary - USGS Fact Sheet
Description: Scientific studies recently begun by the U.S. Geological Survey suggest that several key natural processes and human-induced environmental factors are directly affecting the health of the Lake Pontchartrain Basin, one of America's largest estuaries. An increased knowledge of the critical geologic and estuarine processes affecting the Basin is essential for its management, improving environmental conditions, and mitigating future problems in the region. Such baseline information is of immediate value to planners and decision makers involved in the task of reversing the Basin's environmental degradation and restoring its water and habitat qualities.

USGS OFR 02-411 - Multibeam Mapping of Selected Areas of the Outer Continental Shelf, Northwestern Gulf of Mexico - Data, Images, and GIS
Description: Following the publication of high-resolution (5-meter spatial resolution) multibeam echosounder (MBES) images of the Flower Garden Banks National Marine Sanctuary area of the northwest Gulf of Mexico (Gardner et al., 1998), the Flower Garden Banks National Marine Sanctuary (FGBNMS) and the Minerals Management Service (MMS) have been interested in additional MBES data in the area. A coalition of FGBNMS, MMS, and the US Geological Survey (USGS) was formed to map additional areas of interest in the northwestern Gulf of Mexico (Figure 1) in 2002. FGBNMS chose the survey areas and the USGS chose the MBES. MMS and FGBNMS funded the mapping and the USGS organized the ship and multibeam systems through a cooperative agreement between the USGS and the University of New Brunswick. The objective of the cruise was to map seven regions of interest to MMS and the FGBNMS. This report provides the multibeam bathymetry and acoustic backscatter data, images, FGDC-compliant metadata, and a geographic information system (GIS) project from the 2002 surveys. This report also provides the multibeam bathymetry and acoustic backscatter data, images, and metadata from the 1997 USGS survey of East and West Flower Garden Bank and Stetson Bank.

USGS OFR 02-396 - Cruise Report: R/V Moana Wave Cruise M-1-02-GM: Bathymetry and Acoustic Backscatter of the Mid and Outer Continental Shelf, Head of De Soto Canyon, Northeastern Gulf of Mexico
Description: The mid to outer continental shelf off Mississippi-Alabama and off northwest Florida were the focus of US Geological Survey (USGS) multibeam echosounder (MBES) mapping cruises in 2000 and 2001, respectively. These areas were mapped to investigate the extent of "deep-water reefs" first suggested by Ludwick and Walton (1957). The reefs off Mississippi and Alabama were initially described in water depths of 60 to 120 m (Ludwick and Walton, 1957) but the 2000 mapping found reef and hardgrounds to be much more extensive than previously thought (Gardner et al., 2001). The persistent trend of reef-like features along the outer shelf of Mississippi-Alabama suggested the trend might continue along the northwest Florida mid and outer shelf so a MBES-mapping effort was mounted in 2001 to test this suggestion. It is critical to determine the accurate location, geomorphology, and types of the ridges and reefs that occur in this region to understand the Quaternary history of the area and to assess their importance as benthic habitats for fisheries. The 2001 survey found a series of shelf-depth platforms with ridges (possibly reefs) constructed on their surfaces (Gardner et al., 2002).

U.S. Coral Reefs—Imperiled National Treasures | USGS Fact Sheet 025-02
Description: Coral reefs are home to 25% of all marine species. However, the tiny colonial animals that build these intricate limestone masses are dying at alarming rates. If this trend continues, in 20 years the living corals on many of the world’s reefs will be dead and the ecosystems that depend on them severely damaged. As part of the effort to protect our Nation’s extensive reefs, U.S. Geological Survey (USGS) scientists are working to better understand the processes that affect the health of these ecologically and economically important ecosystems.

Subsurface Controls on Historical Subsidence Rates and Associated Wetland Loss in Southcentral Louisiana
Description: The Gulf Coast Basin is a region where subsidence and fault activation are common around large, mature oil and gas fields even though moderately deep hydrocarbon production has generally been disregarded as the primary cause. This project will test the hypothesis that long-term, large-volume oil and gas production in the Gulf Coast Basin has resulted in land-surface subsidence and activation of deep-seated faults around some fields.
