Phenomena affecting or occurring within the mass of gases that surrounds the earth, including its physics, chemistry, dynamics, and weather conditions.
Photographic survey of the impacts of Hurricane Katrina on the barrier islands, barrier shoreline, and the Mississippi River Delta along the Louisiana coastline. Primary focus is on the ecosystems such as fish, rookeries, and seagrass beds.
Homepage for programs of the Center for Coastal Geology on hurricanes and extreme storms with links to technology, related aerial photography, hurricanes, El Nino, northeasters, and specific storms.
Information on video and still photography used to supplement laser altimetry measurements of the coast. The photography is used for recognizing geomorphic and cultural features impacted by storms. Links to photo collections of hurricanes and El Nino.
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.
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.
Hydrologic monitoring data for Long Valley caldera, California, on springs, streams, wells, fumaroles, and precipitation to study the natural hydrologic variations and the response of the hydrologic system to volcanic and tectonic processes.
Drought map of Kansas link to real-time data for stream gaging stations and links to historic droughts of Kansas, ground water, drought definitions, and references.
