Observations of irrigated agricultural land within the Harquahala Irrigation Non-Expansion Area Groundwater Basin in Arizona. Crops were verified in situ three times in 2021, first on March 3rd, then on May 19th, and finally on September 2nd; based on digitized field boundaries. Field boundaries were digitized from U.S. Department of Agriculture, National Agricultural Imagery Program images dated 2021 and supplemented with Landsat and Sentinel2 imagery collections accessed via the Sentinel Hub, Sentinel Playground (https://apps.sentinel-hub.com/sentinel-playground). Satellite images were also used to identify the length of the growing season and crop condition. Water withdrawals were calculated using the modified...

This database contains spatial data on the location, number, size and extent of energy-related surface disturbances within the Bureau of Land Management’s (BLM) Carlsbad Field Office (CFO) administrative area. The BLM administers over 2 million acres of surface estate and 3 million acres of mineral estate in the southeastern portion of New Mexico. The BLM requires a thorough and comprehensive reasonable foreseeable development (RFD) scenario which quantifies the current and future potential of oil and gas resources and the necessary water use associated with those activities. The database includes: 1) polygons of oil and gas pads generated from automated and manual classification of aerial imagery, 2) polylines...
This imagery dataset consists of 3-meter resolution, lidar-derived imagery of the Marlinton 30 x 60 minute quadrangle in West Virginia. The source data used to construct this imagery consists of 1-meter resolution lidar-derived digital elevation models (DEMs). The lidar source data were compiled from different acquisitions published between 2020 and 2021. The data were processed using geographic information systems (GIS) software. The data is projected in WGS 1984 Web Mercator. This representation illustrates the terrain as a hillshade with contrast adjusted to highlight local relief according to a topographic position index (TPI) calculation.

Macroinvertebrate and environmental data were collected annually in July-August in the year before dike removal (2009) and the first three years after dike removal (2010-2012) at the Nisqually River Delta, Washington, U.S.A. Data were collected along a gradient extending from the inner marsh edge to the delta front and spanning different types of habitat including marsh restored to tidal inundation by dike removal, previously restored marsh, undisturbed reference marsh, and tidal flats. Biological data comprised benthic macroinvertebrate species composition, abundance, and biomass. Environmental correlates included bed elevation; sediment grain size, organic content, and pH; and water column temperature, salinity,...
