Data release for Accounting for Land in the United States: Integrating Physical Land Cover, Land Use, and Monetary Valuation

Land plays a critical role in both economic and environmental accounting. As an asset, it occupies a unique position at the intersection of the System of National Accounts (SNA), the System of Environmental-Economic Accounting Central Framework (SEEA-CF), and (as a spatial unit) SEEA Experimental Ecosystem Accounting (SEEA-EEA), making land a natural starting point for dev

Grand Falls, Arizona: Dune Field Sand Transport 2017 - 2019

As part of a NASA-funded study of sediment flux rates at a Mars analog site, we installed a suite of instruments in a small dune field near Grand Falls, Arizona. Data released in this report was collected from 02/07/2017 to 05/22/2019. The Grand Falls (GF) dune field is located on the Navajo Nation. It lies ~70 km NE of Flagstaff, AZ, 2 km east of Grand Falls, and just nor

Aerial Surveys of Shorebirds at Pre-migratory Staging Sites in Western Alaska, 2018-2019

These data are in one table and document the numbers of four species of shorebird counted during aerial surveys of coastal sites in western Alaska. Survey regions encompassed coastline between the mouths of the Kuskokwim and Yukon rivers, and the northern coast of the Alaska Peninsula from the mouths of the Kvichak and Naknek Rivers to Nelson Lagoon. Surveys were flown from 7-9 September 2018...

Archive of Chirp Subbottom Profile Data Collected in 2019 from Cedar Island, Virginia

From August 9 to 14, 2019, researchers from the U.S. Geological Survey (USGS) conducted a geophysical survey to investigate shoreface morphology and geology near Cedar Island, Virginia. The Coastal Sediment Availability and Flux project objectives include understanding the morphologic evolution of the barrier island system on a variety of time scales (months to centuries) and resolv

Legacy and emerging contaminants in the Chesapeake Bay watershed as measured using passive samplers – 2005 to 2013

Legacy and emerging contaminants were measured in streams and rivers in the District of Columbia and the states of Maryland, Pennsylvania, Virginia, and West Virginia of the Chesapeake Bay watershed between 2005 and 2013. Passive sampling devices, SPMDs and POCIS, were used to sample these waterbodies, providing a time-integrated concentration of contaminants that are potentially bio

Data release for tracking rates of post-fire conifer regeneration distinct from deciduous vegetation recovery across the western U.S.

Post-fire shifts in vegetation composition will have broad ecological impacts. However, information characterizing post-fire recovery patterns and their drivers are lacking over large spatial extents. In this analysis we used Landsat imagery collected when snow cover (SCS) was present, in combination with growing season (GS) imagery, to distinguish evergreen vegetation from deciduou

Seismic reflection imaging of the low-angle Panamint normal fault system, eastern California, 2018

A fundamental question in seismic hazard analysis is whether <30º-dipping low-angle normal faults (LANFs) slip seismogenically. In comparison to more steeply dipping (45-60º) normal faults, LANFs have the potential to produce stronger shaking because of their increased possible rupture area in the seismogenic crust. While LANFs have been documented globally, examples o
