As part of a large-scale study of nitrate contamination on Kirtland Air Force Base in central New Mexico, the USGS collected groundwater and surface water samples for artificial sweetener analyses. Samples were collected following standard USGS procedures (U.S. Geological Survey, variously dated), filtered to 0.45 microns, and frozen until analysis. Artificial sweeteners analyzed include neotame, acesulfame-K, aspartame, saccharin, and sucralose. Of the 49 sites sampled, 17 sites had measurable detections of artificial sweeteners. Neotame was the most commonly detected sweetener (n=12) followed by saccharin (n=5), acesulfame-K (n=2), aspartame (n=1), and sucralose (n=0). Concentrations ranged from 0.0003–0.011 μg/L...

This layer represents fundamentally suitable and unsuitable habitat for freshwater mussels in the Meramec Basin as modeled by these authors on May 17, 2017 based on spatial data ranging from 1990 to 2014. Identification of habitat characteristics associated with the presence of freshwater mussels is challenging but crucial for the conservation of this declining fauna. Most mussel species are found in multi-species assemblages suggesting that physical factors influence presence similarly across species. In lotic environments, geomorphic and hydraulic characteristics appear to be important factors for predicting mussel presence. We used maximum entropy (MaxEnt) modeling to evaluate hydrogeomorphic variables associated...

The U.S. Geological Survey's (USGS) SPAtially Referenced Regression On Watershed attributes (SPARROW) model was used to estimate baseflow changes from historical (1984 - 2012) to thirty-year periods centered around 2030, 2050, and 2080 under warm/wet, median, and hot/dry climatic conditions. SPARROW is a spatially explicit hybrid statistical and process-based model that estimates mean baseflow over the simulation period in streams by linking monitoring data with information on watershed characteristics and baseflow sources, routed through a stream network. This USGS data release includes input and output files associated with SPARROW simulations of baseflow for 10 model runs. Model construction, calibration and...

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,...

The variation of Love/Rayleigh phase and group velocity was determined for the continental U. S. and adjacent Canada. By processing ambient noise from the broadband channels of the Transportable Array (TA) of USArray and several PASSCAL experiments and using some earthquake recordings, the effort was focused toward determining dispersion down to periods as short as 2s. The relatively short distances between TA stations permitted the use of a 25 km x 25 km grid for the four independent tomographic inversions (Love/Rayleigh and Phase/group velocity). One reason for trying to obtain short period dispersion was to have a data set capable of constraining upper crust velocity models for use in determining regional moment...
The application of two management strategies were tested across nine, Class III, wetland catchments located at the Woodworth Study Area (Stutsman County, ND). This field study took place during 2014 and 2015. 2014 was a pre-treatment year and snow measurements were taken in all experimental catchments in the late February 2015, before treatments were applied. Temporary electric fences were installed surrounding each wetland catchment to exclude them from grazing that took place on the management unit in 2015. All the catchments had been managed in a similar manner since purchased by USFWS in 1964. The primary management strategy of the wetland catchments from 1964–2013 was non-use with occasional prescribed burning....

Lifespan distribution in the Chesapeake Bay (CB) salt marsh complex is presented in terms of lifespan of conceptual marsh units defined by Ackerman and others (2022). The lifespan calculation is based on estimated sediment supply and sea-level rise (SLR) predictions after Ganju and others (2020). Sea level predictions are present day estimates at the prescribed rate of SLR, which correspond to the 0.3, 0.5, and 1.0 meter increase in Global Mean Sea Level (GMSL) scenarios by 2100 from Sweet and others (2022). Through scientific efforts initiated with the Hurricane Sandy Science Plan, the U.S. Geological Survey has been expanding national assessment of coastal change hazards and forecast products to coastal wetlands,...

This dataset contains scenario based model projections (2001-2100) of land use related water demand for the California Central Coast in support of the published manuscript "Land-Use Change and Future Water Demand in California’s Central Coast" in the journal Land (https://www.mdpi.com/2073-445X/9/9/322). We used a modified version of the USGS's LUCAS model to examine two future scenarios of future land use and associated water use demand, from 2001 to 2100 across 10 Monte Carlo simulations. We examined a range of potential water demand futures sampled from a 24-year record of historical (1992-2016) data to develop two future land change scenarios including a business-as-usual (BAU) scenario which sampled from the...

This data release consists of lakebed temperature data collected at the sediment-water interface at the north end of Haskell Lake, Lac du Flambeau Reservation, Wisconsin. Data were collected using a fiber-optic distributed temperature sensor (DTS) during a 5 day period from July 27 to August 1, 2016. Established procedures were followed to estimate lakebed temperatures from the raw DTS data and calibration baths of known temperatures. This data release includes the raw DTS (Stokes and anti-Stokes intensity) data, a shape file of the DTS cable location, photos from the field deployment, and python code for reproducing the full workflow described as part of U.S. Geological Survey Scientific Investigations Report 2020-5005....
The Machine Learning Asset Aggregation of the PDE (MLAAPDE) is a waveform archive, feature labeled catalog, and Python module that together provide a routine way to gather high-quality input data to train machine learning models. While all the data provided are already publicly available, MLAAPDE packages it in a format that allows a user to prepare input for common machine learning frameworks with few lines of code. Most of the features that are part of the MLAAPDE dataset are selected from the Preliminary Determination of Epicenters (PDE), the official earthquake catalog of the USGS National Earthquake Information Center (NEIC). The PDE aims to provide a complete catalog of source characterization estimates...

Data were collected between 2013 and 2022 in a research area of the Everglades known as the Decompartmentalization Physical Model (DPM), a wetland area in the central Everglades that includes canals and levees bordering Water Conservation Area 3A (WCA-3A) to the northwest and Water Conservation Area 3B (WCA-3B) to the southeast. During the study more than ten major controlled flow releases occurred by opening the S-152 culverts on canal L-67A that released experimental high flows through the wetland. Here we present the input measurements and metabolism outcomes at 13 wetland sites in the Everglades using the RiverMET workflow (https://doi.org/10.5066/P9TEBOUR) including details about performance metrics.
