We mapped substantial migration of the river channel between the City of Winslow and the Navajo Nation community of Leupp; in a human lifetime the river has moved more than a mile across its valley floor.
Comprehensive background information on coastal land loss, discussing the influence of waves and storms, the intrinsic characteristics of the shoreline materials, and the role of human activities.
Explains biological soil crusts, organism-produced soil formations commonly found in semiarid and arid environments, with special reference to their biological composition, physical characteristics, and ecological significance.
Home page for Coastal and Marine Geology with links to topics of interest (sea level change, erosion, corals, pollution, sonar mapping, and others), Sound Waves monthly newsletter, field centers, regions of interest, and subject search system.
Interactive map server to view and create maps using available coastal and marine geology data sets of offshore and coastal U.S. and the Gulf of Mexico. Links to available data and metadata that can be downloaded.
USGS responses to and studies of the hazards and impact of major hurricanes, tsunamis, and El Nino storms. Includes links to oblique aerial photography and LIDAR surveys recording coastal changes and other effects of storms and waves.
A coordinated set of studies shows development of coastal features, aspects of marine water quality, and impacts of hurricanes along this section of important coastline.
By measuring the current and historical growth rates of coral skeletons, and using field experiments, we intend to find out whether rising atmospheric CO2 and rising sea levels will cause coral reefs to erode and cease to function.
