Afghanistan is endowed with a broad range of mineral resources. Currently, the majority of mining throughout the country is comprised of informal and undocumented artisanal and small-scale mining (ASM) operations. The exact scope of excavation operations depends largely on the mineral commodity produced. In the case of gemstones, such as emeralds and rubies, small teams of miners use manual equipm

This data release serves as an archive of single-beam bathymetric (SBB) data collected in July 2004 (Madison Bay study area; U.S. Geological Survey [USGS] Field Activity Number [FAN] 2004-303-FA) and August 2008 (Bully Camp, Point au Chien, Caminada, Fourchon, and Leeville study areas; USGS FAN 08SWL02) at six study areas in the Mississippi River Delta Plain (MRDP), Louisiana. Data were collected

This data bundle contains some of the inputs, all of the processing instructions and all outputs from a single VisTrails/SAHM workflow. This model specifically includes field data of locations with >40% cover of cheatgrass (presence) and

Data release contains total suspended solids, total phosphorus, nitrate plus nitrite, and total Kjeldahl nitrogen concentration data for the White River at Muncie, near Nora, and near Centerton, Indiana, 1991-2017, and R source code used for model development.

These datasets include wells, springs, and contours used to construct the Hot Springs Highway 270 bypass pre-construction potentiometric-surface map. During the summer of 2017, the U.S. Geological Survey and Hot Springs National Park Service collected groundwater measurements from 66 wells - 59 measurements were used to construct a potentiometric-surface map of wells screened in the Ouachita Moun

This data release comprises the data files and code necessary to perform all analyses presented in the associated publication. The *.csv data files are aggregations of water extent on the basis of the European Commission's Joint Research Centre (JRC) Monthly Water History database (v1.0) and the Dynamic Surface Water Extent (DSWE) algorithm. The shapefile dataset contains the study area 8-digit

This field activity is part of the effort to map geologic substrates of the Stellwagen Bank National Marine Sanctuary region off Boston, Massachusetts. The overall goal is to develop high-resolution (1:25,000) interpretive maps, based on multibeam sonar data and seabed sampling, showing surficial geology and seabed sediment dynamics. This cruise was conducted in collaboration with the Stellwagen B

An idealized domain is setup to test the development of Submerged Aquatic Vegetation (SAV) growth model within the Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST) model. The change in SAV biomass is computed from temperature, nutrient loading and light predictions obtained from coupled hydrodynamics (temperature), bio-geochemistry (nutrients) and bio-optical (light) models. In exchange,

This data product consists of a database of population change and relative abundance estimates for North American birds, estimated from North American Breeding Bird Survey (BBS) data. Data are presented in 6 separate spreadsheets for 2 methods of trend summary and 3 time periods for 548 species of birds. Metadata for the BBS data used to produce these estimates is available from a USGS ftp site (f

This data release contains the shapefiles of mean annual water-budget components for Guam for historic (1990 - 2009) and future (2080 - 2099) climate conditions. Components estimated for the 1990 - 2009 scenario represent an update to the historic (1961 - 2005) components estimated by Johnson (2012), and serve as a historic baseline for the components estimated for the future (2080 - 2099) climate

This data release consists of two .csv files of inverted models of electrical resistivity created from the processed resistivity data in the accompanying two data releases: (Miller and Others, 2018) and (2018 Raw and Processed, in progress). During 2016, 17, and 18, the U.S. Geological Survey conducted continuous resistivity profiling along 15 rivers or lakes in the Mississippi Alluvial Plain of M
