Data

Water chemistry data from wells drilled by brine operations in Bristol and Cadiz Basins in San Bernardino County, California, USA. These data are used in the Journal article: Rosen, M.R, Stillings, L.L., Kane, T., Campbell-Hay, K., Vitale, M., Spanjers, R., in press, Possible sources and mechanisms of anomalous Li and Ca enrichment in the Bristol Dry Lake brine compared to other playa...

This data release contains compiled groundwater withdrawal data from 1980 to 2018 for the Hueco Bolson, Mesilla Basin, and the Rio Grande alluvium in El Paso and Hudspeth Counties, Texas. Most groundwater withdrawal volumes were distributed to wells and separated into water-use categories. The data were compiled, distributed, and categorized as part of the U.S. Geological Survey’s...

The U.S. Geological Survey (USGS) in cooperation with the Harris‐Galveston Subsidence District, City of Houston, Fort Bend Subsidence District, and Lone Star Groundwater Conservation District has produced this dataset of groundwater‐level altitudes and groundwater‐level altitude changes in the Chicot, Evangeline, and Jasper aquifers in the Houston‐Galveston region, Texas. This dataset...

The U.S. Geological Survey collected groundwater samples from 50 wells used for domestic and small system drinking water supplies in Shasta and Tehama Counties, California in 2018-2019. The wells were sampled for the Redding-Red Bluff Shallow Aquifer Study Unit of the California State Water Resources Control Board Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority...

Mono Lake is a hypersaline soda lake rich in dissolved inorganic arsenic with its primary production currently dominated by Picocystis str. ML. We set out to determine if this picoplankter could metabolize inorganic arsenic, and in doing so form unusual arsenolipids (e.g., methylated arsinoyl ribosides) as reported in other saline ecosystems and by halophilic algae. We cultivated...

GSFLOW is a coupled Groundwater and Surface-water FLOW model based on the integration of the USGS Precipitation-Runoff Modeling System (PRMS-V) and the USGS Modular Groundwater Flow Model (MODFLOW-2005 and MODFLOW-NWT). GSFLOW was developed to simulate coupled groundwater/surface-water flow in one or more watersheds by simultaneously simulating flow across the land surface, within...

These data are part of the Gulf Watch Alaska (GWA) long term monitoring program, nearshore monitoring component. Specifically, these data describe sea otter (Enhydra lutris) aerial survey observations from the waters around Katmai National Park and Preserve from surveys conducted in 2008, 2012, 2015, and 2018. Sea otters are a keystone predator, well known for structuring the nearshore...

GW_Chart is a program for creating specialized graphs used in groundwater studies. It incorporates the functionality of two previous programs, Budgeteer and Hydrograph Extractor and adds additional new features. There are seven major types of graphs created with GW_Chart: Calibration Plots Water Budget Plots Hydrographs Lake Plots Piper Diagrams Cell Water Budgets Farm Budgets It reads...

The dataset consists of a polygon shapefile. Each polygon represents a set of molt units (interconnected lakes used as habitat by molting waterfowl) within the Goose Molting Area of the Teshekpuk Lake Special Area in northern Alaska, in addition to a half-mile or 1-mile wide buffer, that were selected for restrictions on new surface occupancy or infrastructure development by the oil and...

We produced a time series of maps of habitat structure within wetlands of the Central Valley of California. The structure of open water and tall emergent vegetation, such as Typha spp. and Schoenoplectus spp., is critical for migratory birds. Through field observation and digitization of high resolution imagery we identified the locations of tall emergent vegetation, water, and other...

This dataset contains the point-transect distance sampling records of Hawaii Akepa collected at Hakalau Forest National Wildlife Refuge in 2002, including survey point locations, distance to detected birds, number of detected birds, elevation, and alliance-level habitat classification. This data release consists of two tabular datasets, one that contains distances and the other that...

This data release includes data and metadata on litterfall rates, foliar nitrogen and carbon, grass biomass, soil nitrogen and carbon, and native outplant survival rates for an experiment that added large quantities of woody litter to a restoration forest in an attempt to lower soil nitrogen and exotic grass biomass. All sites were within Hakalau Forest National Wildlife Refuge on Hawaii...
