Have an Earth Science question?   Ask-A-Geologist! 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.

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.
