Recent data syntheses have clarified future relative sea-level rise exposure and sensitivity thresholds for drowning. We integrated these advances to estimate when and where rising sea levels could cross thresholds for initiating wetland drowning across the conterminous United States. We evaluated three sea-level rise thresholds for wetland drowning (4, 7, and 10 mm/yr). Our study area spans the c

This data release contains an international compilation of 656 peak discharge estimates of floods and runoff-generated debris flows. The data (“DimensionlessDischarge.csv” and “CrossSections.csv”) were obtained from the literature and measured in the study Cavagnaro and others (2024). The dataset also includes information about flow depth, flow type (flood or debris flow), flow cross-sectional are

To support floodplain forest research and management actions on the Upper Mississippi River System (UMRS), contiguous forested areas in the UMRS floodplain were developed and a wide range of attributes were created that define basic ecosystem conditions within such forested areas. The data allows users to query on a set of attributes (e.g., size, shape, inundation characteristics, etc…) to visuali

These data were compiled to support stranding risk modeling of young-of-year rainbow trout in Glen Canyon resulting from fluctuating flows from Glen Canyon Dam, called Trout Management Flows (TMFs). The objective of our study was to evaluate the stranding risk associated with different TMFs. We used the results of a 2-dimensional hydrodynamic model (Wright and others, 2024) as input to a rainbow t

This data release comprises the tabular data used to develop regression equations for estimating selected low-flow statistics for ungaged streams in Ohio that are not substantially affected by regulation, diversions, or other anthropogenic influences, and the geographic information systems (GIS) layer to implement them in the U.S. Geological Survey StreamStats application (https://streamstats.usgs

The 2021 Horne Fire on Isle Royale National Park (ISRO) ignited when lightning struck the island near Duncan Bay on August 10, 2021, during elevated drought conditions. Per the National Park Service, it would continue to burn slowly and spread until a wind event on August 21, 2021 caused significant spread and initiated a control effort to protect historical structures in Tobin Harbor. The fire wa

This data release presents chemical and biological results from an investigation of the uptake of per- and polyfluoroalkyl substances (PFAS) from groundwater contaminated by fire training activities on Cape Cod, Massachusetts conducted from July to August 2019. An exposure experiment was conducted at an a PFAS contaminated site (FTA-1) near the fire training area (FTA). To assess the tissue-specif

Per- and polyfluoroalkyl substances (PFAS) and co-occurring inorganic and organic contaminants are widely distributed in the environment and understanding their surface water sources is critical for water resource management. In November 2021, 13 sites were sampled along a stream reach in the Neshaminy Creek basin in southeastern Pennsylvania utilizing a time of travel sampling approach. The reach

These data describe the results of a controlled laboratory mesocosm experiment evaluating the effect of nitrapyrin, a nitrification inhibitor, on nitrification in a nitrifier enriched microbial (NEM) community. Parameters described include the water chemistry and nitrapyrin measurement results of experimental mesocosms. Microbial community data is described in a separate data release.

This data set contains toxicity data from 28- and 84-day sediment bioassays to assess the effects of contaminated Kanawha River, West Virginia sediment on juvenile mussels (fatmucket, Lampsilis siliquoidea) and one commonly tested benthic invertebrate (amphipod, Hyalella azteca) following ASTM standard methods for conducting 4-week sediment toxicity tests with the mussel and amphipod. In addition,

The dataset consists of synthetic seismograms recorded using the SPECFEM3D wave propagation software. Data from 8 isotropic earthquake sources were recorded at 630 stations while data from 8 realistic earthquakes were recorded at 520.
