Measured precipitation data are formatted in regular font while correlated data are italicized. Table 2 contains tritium in precipitation for ninety-six 2-degree latitude by 5-degree longitude quadrangles covering the continental U.S. Latitudes are north of the equator...
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 and anticlines. For example, Butler Cave is an elongate cave where the trunk channel follows the axis of Sinking Creek syncline and most of the side passages follow joints at right angles to the syncline axis. In contrast, the Water Sinks Subway Cave, Owl Cave, and Helictite Cave have abundant maze patterns, and are located near...

Using publicly available data for Madison and Oneida counties, New York, a series of geospatial overlays were created at 1:24,000 scale to examine the bedrock geology, groundwater table, soils, and surficial geology. Bedrock and surficial geology were refined using extant bedrock maps, well and borehole data from water- and gas-wells, soil data, and lidar data. Groundwater data were collected from New York State Department of Environmental Conservation and U.S. Geological Survey water-well databases to estimate the groundwater table. Soil data were used to examine soil thickness over bedrock and infiltration. An inventory of closed depressions was created using reconditioned lidar-derived bare-earth digital elevation...

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 were used to acquire additional cost information. The accuracy of estimates is not known but we assume that most estimates represent close to the total cost or the minimum financial cost, with overestimates being rare. Total cost information could include component costs related to project planning, dam deconstruction cost, and several...

The development and deployment of digital broadband seismographs provides the data required to rapidly assess earthquake size, determine source parameters and better characterize ground motions affecting earthquake hazard. The focus of regional moment tensor analysis is to estimate the moment magnitude, faulting parameters and source depth of earthquakes that are too small to be recorded teleseismically. Thus they have the potential of extending the earthquake catalog to magnitudes less than about M4-4.5. This data distribution provides the details required to critically review the resulting catalog, e.g., the waveforms used, processing parameters and velocity model. In addition the issue of the correct local...

The timing of biological events in plants and animals, such as migration and reproduction, is shifting due to climate change. Anadromous fishes are particularly susceptible to these shifts, as they are subject to strong seasonal cycles when transitioning between marine and freshwater habitats to spawn. We used linear models to determine the extent of phenological shifts in adult alewife (Alosa pseudoharengus) as they migrated from ocean to freshwater environments during spring to spawn at 12 sites along the northeast U.S. We also evaluated broad-scale oceanic and atmospheric drivers that trigger their movements from offshore to inland habitats including sea surface temperature (SST), North Atlantic Oscillation index,...

Wetlands are frequently used in the U.S. for treating nitrate in agricultural runoff. However, numerous other biologically active contaminants, such as antibiotics and nitrification inhibitors, regularly co-occur with nitrate and many can affect the efficiency of nitrate removal. This project evaluated the discrete and combined effects of specific veterinary and human antibiotics and a common nitrification inhibitor (nitrapyrin) on nitrate-N treatment efficiency in saturated sediments and floating treatment wetlands. Sediment and water samples were collected from 3 locations at the USDA Meat Animal Research Facility near Clay Center NE in August 2019 for assessment of background conditions in order to determine...
