Phenomena affecting or occurring within the mass of gases that surrounds the earth, including its physics, chemistry, dynamics, and weather conditions.
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.
Shows how observations and modeling can help anticipate practical problems in coastal areas when hurricanes arrive. Focuses primarily on areas where people have built houses and roads that may be destroyed during storms.
Recent physical changes over time, including trends toward earlier snowmelt runoff, decreasing river ice, and increasing spring water temperatures, may affect salmon populations; we want to know how important these effects are.
Overview of the environmental monitoring component of the international program at the EROS Data Center using Geographic Information Systems (GIS) technology, with links to data, partners, publications, and workshops.
Explains sources of mercury in the air, ways in which mercury is concentrated in animals, and describes how we measure deposition of atmospheric mercury, with summaries of observations.
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.
The Maine Cooperative Snow Survey collects, interprets, and distributes information on the depth and water content of Maine's snowpack in the late winter and early spring, when the danger of flooding in Maine's rivers and streams is greatest.
