The USGS National Elevation Dataset (NED) has been developed by merging the highest-resolution, best quality elevation data available across the United States into a seamless raster format. NED is the result of the maturation of the USGS effort to provide 1:24,000-scale Digital Elevation Model (DEM) data for the conterminous US and 1:63,360-scale DEM data for Alaska. The dataset provides seamless coverage of the United States, HI, AK, and the island territories. NED has a consistent projection (Geographic), resolution (1 arc second), and elevation units (meters). The horizontal datum is NAD83, except for AK, which is NAD27. The vertical datum is NAVD88, except for AK, which is NAVD29. NED is a living dataset that...

Two 21-day field operations were conducted in 1997 and 1998 in the estuaries and on the inner continental shelf off the northern Oregon and southern Washington coast. These cruises aboard the R/V Corliss were run in order to generate reconnaissance maps of the seafloor geology and the shallow subsurface stratigraphy using sidescan-sonar and seismic-reflection mapping techniques. The 1998 cruise also collected sediment grab samples, bottom photographs, and video images to verify the sidescan-sonar imagery and to document the seafloor geology. The combination of these data with previously collected sediment sample data (Roberts, 1974; Nittrouer, 1978; and Smith et. al., 1980) has been used to define the extent and...

Patterns displayed by climate forcings and hydrologic responses may be overlooked at a local scale and the co-variation of precipitation, temperature and other atmospheric conditions may not be evident until viewed from a regional spatial scale. The appraisal and management of the Nation's water resources requires the extraction of as much order and predictability from hydro-climate data as possible and thus requires a regional perspective. Temporal climate variations result from a wide range of physical, chemical, and biological processes, including chaotic or near-chaotic fluid dynamics, complex radiative and thermodynamic processes, tropical/extra-tropical interactions, ocean-air interactions, and the responses...

Local Climatological Data is a historical digital data set (DSI-3715) archived at the National Climatic Data Center (NCDC). The local climatological data file is produced from National Weather Service (NWS) first and second order stations. These data are contained in the LCD monthly and annual publications. The annual publications are offered on CD-ROMs beginning with year 2000. Please see the other C00128 record for information on these newer annuals. The monthly summaries include maximum, minimum, and average temperature, temperature departure from normal, dew point temperature, average station pressure, ceiling, visibility, weather type, wet bulb temperature, relative humidity, degree days (heating and cooling),...

The UYRW is undergoing increasing land and water development to support growing municipal, industrial, and recreational needs. As development proceeds, there is the potential for short- and long-term changes in the quantity and quality of surface-water and groundwater resources. Water-quality data currently are stored in disparate formats among numerous Federal, State, and local agencies, private consulting firms, universities, and stakeholder groups. Development of a publically-accessible water-quality database (Data Repository) standardizes and unifies data from the numerous sources. These data can be used to assess water quality in the UYRW and develop a water-quality monitoring plan by identifying data gaps...

Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field values and locations. This dataset presents latitude, longitude, altitude, and magnetic-field values.
This map layer portrays the estimated use of water in counties in the United States, in the year 1995. The map layer was extracted from the U.S. Geological Survey Water Resources of the United States water use database, which is a long term data set that documents information on water use since 1950. This map layer contains information about water use for public supply, industrial, irrigation, mining, livestock, and thermoelectric power, by county throughout the United States.
