Sea-Level Change:
about this Topic

Global sea level has always fluctuated depending on the climate. When the climate cools, more ice accumulates at the Earth's poles and sea level drops. When that ice melts, sea level rises. These changes are identifiable in the rock record and ice layers. CMG research aims to understand this cycle and its effects on the marine and coastal environments.

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
Coastal Classification Mapping Project
Description: A Coastal Classification Map describing local geomorphic features is the first step toward determining the hazard vulnerability of an area. The Coastal Classification Map series of the National Assessment of Coastal Change Project presents ground conditions such as beach width, dune elevations, overwash potential, and density of development. In order to complete a hazard vulnerability assessment, that information must be integrated with other information, such as prior storm impacts and beach stability.

Publication
An Overview of Coastal Land Loss: With Emphasis on the Southeastern United States
Description: 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.

USGS Fact Sheet 095-02: Vulnerability of U.S. National Parks to Sea-Level Rise and Coastal Change
Description: Vulnerability of U.S. National Parks to Sea-Level Rise and Coastal Change

Publication
Assessment of Coastal Vulnerability to Sea-Level Rise: Preliminary Results for the U.S. Gulf of Mexico Coast
Description: This report estimates relative vulnerability to sea-level rise of different coastal environments in the U.S. Gulf of Mexico. This initial classification is based on coastal geomorphology, regional coastal slope, rate of sea-level rise, wave and tide characteristics, and historical shoreline change rates.

Educational Materials
A Photo Gallery of Florida's Big Bend Tidal Wetlands
Description: This collection offers a thematic tour of Florida's Big Bend tidal wetlands, covering aspects of the flora, fauna, and geology of this mosaic of tidal marsh, coastal forest, and winding tidal creeks.
updated: 2001-02-23 pages include:

Research Project
Gulf of Mexico and Southeast Tidal Wetlands
Description: This project is investigating the loss of coastal wetlands and adjacent uplands in order to determine long-term change in wetlands and to provide a model for determining areas that are most vulnerable to loss because of combinations of human and natural impacts.

Publication
Sea-level Rise and Coastal Forests on the Gulf of Mexico - Open File Report 99-441
Description: Sea-level Rise and Coastal Forests on the Gulf of Mexico is a 127-page report discussing the effects of sea-level rise and storm impacts on coastal forests of the Gulf of Mexico. Separate chapters are devoted to non-mangrove and mangrove forests. Information on the responses of individual tree species to increased salinity and flooding is included.
