Seafloor features identified as headward eroding mass failure scarps were digitized by hand from high-resolution multibeam bathymetry compilations (30 m grids) across the Cascadia subduction zone, which spans the region offshore of northern California, Oregon and Washington. These features were initially published by Hill et al. (2022; https://doi.org/10.1016/j.epsl.2022.117797) and here...

This data release contains individual freshwater mussel data used in an augmentation effort within the Clinton River watershed located near Detroit, Michigan in September 2024. Mussels were individually tagged with a unique identification tag, and a subset of mussels received a passive integrated transponder tag to be able to detect their location in June 2024. All mussels were measured...

This dataset represents active relocations of telemetry tagged Black Carp in the Mississippi and Osage rivers of Missouri and efforts to recapture these tagged fish for recovery of data logging tags by a suite of gears and techniques. We actively relocated tagged fish and targeted individuals with gill nets and trammel nets with electrofishing or physical disturbance of the water column...

Data describe the detection of female mitotypes from spectaclecase (Cumberlandia monodonta) and mucket (Ortmanniana ligamentina) freshwater mussel environmental DNA (eDNA) from water samples collected from the Big Piney River in Pulaski County, MO, U.S.A. Water samples were collected from 3 sites known to contain the target species. Sampling transects spanned from 100 meters upstream of...

Accurate age estimation is crucial for understanding fish population dynamics, yet daily age validation for invasive Grass Carp in the Midwestern U.S. is lacking. We validated daily otolith increment deposition in known-age Grass Carp reared in laboratory and pond environments. Larval Grass Carp from captive broodstock were sampled between 6- and 120-days post-hatch. Lapilli otoliths...

The U.S. Geological Survey (USGS), in cooperation with the National Marine Sanctuary Program of the National Oceanic and Atmospheric Administration (NOAA), has conducted seabed mapping and related research in the Stellwagen Bank National Marine Sanctuary (SBNMS) region since 1993. The interpretive datasets and source information presented here are for quadrangle 3, which is one of 18...

These data were compiled to investigate competitive interactions between Pleurphis jamesii and other herbaceous plants in a semiarid grassland community. The objectives of our study were to determine whether selective mortality of either C3 or C4 herbaceous plants led to changes in (1) soil moisture during the growing season, (2) water use by Pleuraphis jamesii during the growing season...

To assess historical environment changes associated with changes in hydrologic connection to the Gulf Intracoastal Waterway (GIW) and Mobile Bay, six sediment cores (50-80 cm in length) were collected in 2021 from two coastal wetland sites. These two sites in Gulf Shores, Alabama were: Oyster Bay Nature Preserve ("OB", a brackish marsh with natural hydrology) and the Emmet O. and Vina...

The U.S. Geological Survey (USGS) maintains shoreline positions for the United States coasts from both older sources, such as aerial photos or topographic surveys, as well as contemporary sources like lidar elevation point clouds and digital elevation models (DEMs). These shorelines are compiled and analyzed in the Digital Shoreline Analysis System (DSAS) software to compute rates of...

A generalized hydrologic stream network (GenNet) consisting of 263,494 generalized flowlines, inclusive of coastline and terminating flow paths, was constructed for the conterminous United States (CONUS) to support efficient dynamic modeling of nutrient loads, streamflow, and downstream transport of other contaminants in streams. GenNet was generalized from the base network E3NHDPlusV2...

This data release includes whole rock (WR) geochemical data. Bureau Veritas Commodities Canada Ltd. Laboratories in Vancouver, British Columbia, Canada analyzed the samples. Meghan Toft and Greg Walsh collected the rock samples from outcrops in the 7.5-minute Paradox Lake quadrangle, New York. The whole rock geochemistry data constrain the composition of mapped rocks in the eastern...

Data describe environmental DNA (eDNA) concentrations from invasive silver and bigheaded carp (Hypophthalmichthys spp.) in Missouri’s Blackwater and Lamine Rivers in 2015. Two, 3-day sampling trips were conducted in March and September 2015 (winter and summer samples, respectively) to collect water samples and associated water quality data. Parameters include locations of collected water...
