Broad overview of USGS research and monitoring designed to understand current changes in the context of prehistoric and recent earth processes, distinguishing between natural and human-influenced changes, and recognizing ecological and physical responses
Site for a USGS project under the U.S. Global Change Research Program for a national assessment of the impacts of climate variability and change on resources with links to impacts in Alaska, western U.S., public lands, and water resources.
Review of the Global Change Hydrology Program components relating to hydroclimatology and studies of the biogeochemistry of greenhouse gases with links to research activities, datasets, fact sheets, and other publications and websites.
Homepage for USGS Global Change Research projects which seek to understand the interrelationships among earth surface processes, ecological systems, and human activities. Links to projects with descriptions and products and downloadable poster.
Overview of interdisciplinary research studies in Glacier National Park to understand how this mountain wilderness responds to present climatic variability and other external stressors, such as air pollution, and links to detailed reports.
The Hydro-Climatic Data Network, or HCDN, consists of streamflow records for 1,659 sites throughout United States and its Territories. Records span the period 1874 through 1988, and represent a total of 73,231 water years of information.
Plain-language questions and answers about the stable-isotopic record obtained from Devils Hole, a cave in south-central Nevada. The data do not agree with the Milankovitch hypothesis concerning the causes of glacial cycles in climate change.
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.
Report with mini-movie and photos on the hypothesis that the atmospheric transport of dust arising from the desertification in northern Africa led to algal infestation of corals, coral diseases, and the near extinction of associated sea urchins.
Homepage for Earth Surface Processes Team with research studies in two general categories: climate change and geologic mapping. Links to research activities, available data sets, workshop, and programs.
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.
Summary of a circular on USGS environmental research and Chesapeake Bay with links to full document. Includes discussion of the problems of the estuary, restoration efforts, water quality, and effects on ecosystem.
Summary of part of the USGS interdivisional Mississippi Basin Carbon project that will study the changes in climate and the environment through carbon cycle changes recorded in lake sediments in the Upper Mississippi River Basin.
Homepage for project on Bear Lake, Idaho-Utah, to study past climate change and effect on lake catchment basins. Includes link to summary, personnel, geology, methods used including coring and seismic surveying, and publications.
