Data

This data release provides the source data and results of a flood frequency analysis for sites in the Mendenhall River Basin, Alaska, that was conducted using USGS PeakFQ software (Veilleux and others, 2014; Flynn and others, 2006). Data are provided for two streamgages that had at least 10 years of annual peak-flow record. The data include streamgage information, PeakFQ input (.txt and...

Beginning at about 2:15 am on May 27, 2016, a landslide from the headscarp of the May 25, 2014, West Salt Creek rock-avalanche deposit (White and others, 2015; Coe and others, 2016; Lewis and others, 2023; Coe and others, 2026) moved into a sag pond at the head of the deposit. At about 2:30 am, the landslide caused the sag pond, which already had an elevated water level due to runoff...

Surface water storage, including wetlands and lakes, is not typically considered in hydrological model calibrations. We tested a multivariate calibration process (Latin Hypercube Sampling), incorporating Sentinel-1/2 surface water storage, for a Soil and Water Assessment Tool model across the 0.5 million km^2 Upper Mississippi River Basin. While 19% of the 2000 parameter sets adequately...

These data were compiled in support of the Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead (Post 2026) Environmental Impact Statement (EIS). Specifically, these data present modeled risks to paleontological and cultural resource preservation based on projected reservoir water level fluctuations between December 2026 and December 2060 within Lake Powell and...

This dataset contains known occurrence locations for Myotis lucifugus in interior Alaska derived from the North American Bat Monitoring program and randomly generated pseudo-absence locations. Each location has a suite of vegetation measurements (percent cover measured at 1-km resolution) derived from the Alaska Center for Conservation Science (Nawrocki et al. 2023).

Metal concentrations were measured in samples collected in September 2023 and June 2024 at sites located in the lower Panther Creek watershed (Idaho) where historical mine wastes are present. In addition to legacy mining, the study area encompasses the Leesburg and Mackinaw Mining Districts, which were impacted by the 2022 Moose Fire. Samples included periphyton, seston, aquatic insect...

These data document over a century of plant community change on the Colorado Plateau (CP) using repeat photography (1910-2016). Photos were taken across a 3100 square kilometer area on the CP largely in areas administered by the NPS and Bureau of Land Management (BLM), including (but not limited to) areas now within Arches National Park and Canyonlands National Park; Glen Canyon National

The datasets were collected as part of a project to model fire refugia and severity from remotely sensed vegetation, topographic, fire weather, and fire growth variables. These data were used to evaluate changes in patterns of fire refugia and severity in relation to drivers. They represent a key deliverable of this research, designed to inform conservation and management across the...

Hormone levels (corticosterone, testosterone) and associated sampling information (date, year, month, reproductive season, sampling location, time to bleed) from free-ranging male invasive Burmese pythons (Python bivittatus) in South Florida. Dataset also includes morphometric data (mass, length, circumference, age) of each individual male sampled during the years of 2018 to 2024.

Ecological models facilitate the evaluation of alternative approaches to restore the Greater Everglades ecosystem. However, the provision of useful and accessible models is a challenge because there is often a disconnect between model developers and model users such as natural resource managers and decision makers. Joint Ecosystem Modeling (JEM) meets this challenge by providing...

This data release contains respiration and clearance rate data collected from laboratory experiments. Fatmucket mussels (Lampsilis siliquoidea) were placed in sealed containers to determine their oxygen consumption and excretion rates at two different environmentally relevant temperatures. Mussels were then placed into containers with food to determine how quickly they consume 2-60...

The orthoimagery, digital surface model and point cloud presented here document conditions at Erie Ponds of the St. Louis River Area of Concern in Duluth, Minnesota in August 2020, prior to planned ecological restoration. Aerial images were collected using a DJI Phantom with FC6310 sensor at a nominal elevation of approximately 100 meters above the surface of the lake water. Data were...
