This website discusses the USGS Coastal and Marine Geology Program's studies of the extent and causes of hurricanes' and extreme storms' coastal impacts in order to improve the ability to predict coastal change. Students can find a tutorial about hurricanes, El Ni'os, and Northeasters. The site provides a map of the current tropical storm tracks. Researchers can learn about the USGS's use of video and photographs to assess a hurricane's impact to the geomorphic features of the landscape that are not easily recognized in topographic data. The site also discusses USGS's use of lidar data and provides an interactive lidar mapping display.
