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.

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.
