Airborne scanning laser surveys (LIDAR) are used to obtaining data to investigate the magnitude and causes of coastal changes that occur during severe storms. Links to examples of coastal mapping during specific hurricanes.
Hurricane and extreme storm impact studies: hurricanes, El-NiƱo, & northeasters [More info]
Description of three types of severe coastal storm impacts: hurricane impacts on the southeast U.S., extra-tropical storm impacts on the U.S. west coast during El-Nino winters, and 'northeaster' impacts on the U.S. east coast.
PDF Integrated monitoring of ecological conditions in wetland-upland landscapes [More info]
Landscapes of interwoven wetlands and uplands offer a rich set of ecosystem goods and services. Changes in climate and land use can affect the value of those services. We study these areas to understand how they may be changing.
