Data Release for Luminescence: Butler Cave, Burnsville Cove, Bath and Highland Counties, VA Data Release for Luminescence: Butler Cave, Burnsville Cove, Bath and Highland Counties, VA
Burnsville Cove in Bath and Highland Counties (Virginia, USA) is a karst region in the Valley and Ridge Province of the Appalachian Mountains. The region contains many caves in Silurian to Devonian limestone, and is well suited for examining geologic controls on cave location and cave passage morphology. In Burnsville Cove, many caves are located preferentially near the axes of synclines...
Repeat microgravity data from Santa Cruz River, Tucson, Arizona, 2019-2024 (ver. 2.0, June 2025) Repeat microgravity data from Santa Cruz River, Tucson, Arizona, 2019-2024 (ver. 2.0, June 2025)
Relative-gravity surveys were carried out using a ZLS Burris relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations. Absolute-gravity surveys were carried out using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. Vertical...
The Oysters of Chicopit Bay, Florida, 2016-2018 The Oysters of Chicopit Bay, Florida, 2016-2018
This data set was generated to evaluate the status and response of oysters within Chicopit Bay, FL, in the Timucuan Ecological and Historic Preserve during and following dredging completed by the Army Corps of Engineers for the Mile Point Project. It includes live oyster area estimates from aerial images collected in 2016-2018.
Compilation of cost estimates for dam removal projects in the United States Compilation of cost estimates for dam removal projects in the United States
This dataset provides cost estimates for 668 dam removal projects occurring in the United States. Cost estimates were obtained by searching the internet for sources of information that mention the cost of dam removal projects listed in the USGS Dam Removal Information Portal. When cost data were not available for a dam removal but contact information was, then personal communications...
WASP model used to simulate flow and eutrophication in the central Salem River, New Jersey WASP model used to simulate flow and eutrophication in the central Salem River, New Jersey
A one-dimensional surface-water quality model of the central Salem River Basin, New Jersey was developed to examine the causes of eutrophication and predict the effects of reduced point and nonpoint source nutrient loads on water quality. The model was developed using the USEPA WASP code. The model simulates channel flow and the fate and transport of dissolved oxygen, oxygen demands...
Brook trout abundance within pools of Staunton River and Paine Run in Shenandoah National Park from 2012-2021 Brook trout abundance within pools of Staunton River and Paine Run in Shenandoah National Park from 2012-2021
This Data Release provides brook trout abundance records for pool habitats within 2 streams in Shenandoah National Park (Staunton River and Paine Run). The data were collected with 3-pass backpack electrofishing conducted during baseflow conditions between 2012-2021. This dataset enables spatial analysis of brook trout population responses to drought conditions.
