Data Management and Spatial Studies - GGGSC
We provide support for geospatial analyses, mobile field data collection, management of geospatial collections including documentation, and distribution of all dataset types (geophysical, geochemistry, remote sensing (hyperspectral), etc.). GIS and data management support are provided including hyperspectral and geophysical studies that improve capabilities and applications for investigating...
U.S. Geological Survey activities related to American Indians and Alaska Natives: Fiscal years 2009 and 2010
The U.S. Geological Survey is the earth and natural science bureau within the U.S. Department of the Interior. The U.S. Geological Survey provides impartial information on the health of our ecosystems and environment, the natural hazards that threaten us, the natural resources we rely on, the negative effects of climate and land-use change, and the core science systems that help us provide timely,
EPA method 1312 (synthetic precipitation leaching procedure); leachate chemistry data for solid mine waste composite samples from Silverton and Leadville, Colorado
The EPA Method 1312 Synthetic Precipitation Leaching Procedure (SPLP) leachate chemistry data for mine waste samples is presented. Four mine waste composite samples were collected from Silverton (YUK and MAY) and Leadville (SUN and VEN), Colorado and were extracted following the EPA Method 1312 procedure. Leachate pH values ranged from 2.68 to 3.37 and the samples were ranked by increasing pH: VEN
The effect of acidic, metal-enriched drainage from the Wightman Fork and Alamosa River on the composition of selected wetlands in San Luis Valley, Colorado
The biogeochemistry of selected wetlands in the San Luis Valley, Colorado, was examined to assess the effect of acidic, metal-enriched water draining mineralized areas near and around the Summitville Mine. The sampling protocols, analytical methods, and chemical composition of water and stream bed sediment from the Wightman Fork and Alamosa River as well as water, surface sediment or cores, and ro
