Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Watershed potential erosion rate ranking system and check-dam placement suitability data within the Southern Rockies Landscape Conservation Cooperative (SRLCC)
Using Natural Resource Conservation Service (NRCS) soil databases, topographic features derived from digital elevation models, stream networks, and regional climatic patterns, I developed a ranking system for watershed potential erosion rates and suitability for check-dam placement across the SRLCC. This ranking system serves as a first step for land managers to prioritize areas for check-dam inst
Spatial predictions of habitat suitability for present-day (1950 - 2000 yr) and mid-Holocene (8.3 ka - 4.2 ka) time intervals
This dataset provides spatial predictions of habitat suitability for current (1950 - 2000 yr) and mid-Holocene (8.3 ka - 4.2 ka) intervals using hindcasting, and three separate paleo-distributions calibrated on the packrat midden archive: those without bias correction (naive), those created with a standard method (standard), and those created with a novel alternative (modeled) incorporating a thre
Remotely sensed variables analyzed and reported in the paper titled "Multi-year data from satellite- and ground-based sensors show details and scale matter in assessing climate’s effects on wetland surface water, amphibians, and landscape condi
The comma-delimited fields in this dataset provide values for the remotely sensed variables analyzed for landscape blocks described in the paper, "Multi-year data from satellite- and ground-based sensors show details and scale matter in assessing climate’s effects on wetland surface water, amphibians, and landscape conditions," by Sadinski et al. (submitted). The field labeled “BlockSite” links th
iCoast - Did the Coast Change? Crowd-Sourced Coastal Classifications for Hurricane Sandy
On October 29, 2012, Hurricane Sandy made landfall as a post-tropical storm near Brigantine, New Jersey, with sustained winds of 70 knots (80 miles per hour) and tropical-storm-force winds extending 870 nautical miles in diameter (Blake, et. al, 2013). The effects of Sandy's winds and storm surge included erosion of the beaches and dunes as well as breaching of barrier islands in both natural and
2017 U.S. Geological Survey/BC Hydro seismic data recorded at three dam sites on Vancouver Island, British Columbia, Canada
In May 2017, we acquired high-resolution seismic profiles near three dam sites (Strathcona, Laodre and John Hart dams) located on Vancouver Island, British Columbia, Canada. Our goal was to measure seismic velocities (particularly Vs) at each dam site using body and surface waves. The data were analyzed using refraction tomography and multi-channel analysis of surface waves (MASW), especially in t
Bathymetry and Storage Capacity of Nimrod Lake, Arkansas
A bathymetric survey of Nimrod Lake, Arkansas, was conducted in late April to mid-May, 2016, by the Lower Mississippi-Gulf Water Science Center (LMG WSC) of the U.S. Geological Survey (USGS) using methodologies for sonar surveys similar to those described by Wilson and Richards (2006) and Richards and Huizinga (2018). Point data from the bathymetric survey were merged with point data from an aeria
Update to the groundwater withdrawals database for the Death Valley regional groundwater flow system, Nevada and California, 1913-2010
Groundwater withdrawal estimates from 1913-2010 for the Death Valley regional groundwater flow system (DVRFS) are compiled in a Microsoft Access database. This database updates two previously published databases (Moreo and others, 2003; Moreo and Justet, 2008). A total of about 38,000 acre-feet of groundwater was withdrawn from the DVRFS in 2010, of which 47 percent was used for irrigation, 22 per
Organic and total carbon analyses of rock core collected from boreholes 83BR, 84BR, 85BR, 86BR, 87BR, 88BR, and 89BR in the mudstone underlying the former Naval Air Warfare Center, West Trenton, New Jersey
These data sets present results for analyses of the fraction of total and organic carbon in samples of rock core collected from boreholes 83BR, 84BR, 85BR, 86BR, 87BR, 88BR, and 89BR in the Lockatong Formation (mudstone) underlying the former Naval Air Warfare Center, West Trenton, New Jersey.
Evaluating chronic toxicity of sodium chloride or potassium chloride to a unionid mussel (Lampsilis siliquoidea) in water exposures using standard and refined toxicity test methods
Individual measurements of toxicity and water quality data used to calculate means reported in the associated publication. The objectives of the present study were to (1) refine test conditions for improving mussel survival and growth in a long-term feeding study, (2) evaluate chronic toxicity of NaCl and KCl to fatmucket under traditional test conditions outlined in ASTM (ASTM 2017) and the refin
Continuous Detection PIT Array Data & Model
These data represent a set of capture histories of rainbow trout (Oncorhynchus mykiss or RBT) captured in the Colorado River (CR) and(or) detected on the multiplexer array in the Little Colorado River (LCR). Capture trips to the Colorado River occurred in April 2012, July 2012, September 2012, January 2013, April 2013, July 2013, September 2013, January 2014, April 2014, July 2014, and September 2
Continuous temperature measurements to assess upstream connection of off-channel features of the middle and upper Willamette River, Oregon, Summer, 2016
Temperature loggers were placed on the ground (n=4) and hung in the air (n=2) near the upstream connection point of four Willamette River off-channel features (side channels and alcoves) to assess timing and discharge conditions when these four off-channel features were inundated at the upstream end with flow from the main channel. Temperature readings indicate that the upstream end of an off-chan
