Phenomena affecting or occurring within the mass of gases that surrounds the earth, including its physics, chemistry, dynamics, and weather conditions.
Map of Pleistocene pluvial lakes in the western Great Basin (Nevada, eastern California, southern Oregon). Includes metadata, online PDF map view, and downloadable ArcInfo export files, ArcView shapefiles, and TIFF files.
Discusses the nature and extent of extreme hydrologic events, with supporting observations of the water conditions and their effects on human activities.
Accelerating loss of mass, weakening correlation with the Pacific Decadal Oscillation, and increasing mass turnover likely are the result of changes to warmer and drier climate conditions that are affecting three well-studied glaciers.
Describes the analytical process by which spatial scientific information contributes to forecasts and models in support of regional and local decision-making.
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.
A systematic presentation of climatic and hydrogeologic framework of the area, regional analysis of ground-water recharge, and an overview of 8 site-specific case studies.
Proxy methods allow us to estimate ancient ocean temperatures but only if the method is calibrated using modern samples for which we measure the temperature. This is a proxy method using a sediment trap to collect planktonic foraminifera.
