MODPATH Model Used to Evaluate Flowpaths from Two Contaminant Plume Source Areas near Joint Base Cape Cod, Western Cape Cod, Massachusetts MODPATH Model Used to Evaluate Flowpaths from Two Contaminant Plume Source Areas near Joint Base Cape Cod, Western Cape Cod, Massachusetts
The U.S. Geological Survey (USGS) used an existing groundwater flow model to determine steady-state groundwater flowpaths from two contaminant plume source areas by using a particle tracking post-processing model (MODPATH; Pollock, 2012) as part of an assessment of potential contaminant discharge at the coast in Bourne, Massachusetts. The extents of the source areas, originating from two...

Data supporting "Detecting bumble bees in the wild using environmental DNA: development and validation of a qPCR assay for the endangered Franklin's bumble bee (Bombus franklini)" Data supporting "Detecting bumble bees in the wild using environmental DNA: development and validation of a qPCR assay for the endangered Franklin's bumble bee (Bombus franklini)"
This dataset includes quantitative polymerase chain reaction (qPCR) data for an in vitro test of the Bombus franklini eDNA assay using target and nontarget DNA extract, qPCR data for a plate used to calculate the limits of detection and quantification of the assay based on serial 10-fold dilutions of B. franklini gBlock, qPCR data for an in situ test of the assay using flower samples...
Northwestern Bay of Bengal (IODP Site U1445) Late Pliocene Paleosalinity Estimates Northwestern Bay of Bengal (IODP Site U1445) Late Pliocene Paleosalinity Estimates
Data are estimates of salinity based upon down-core planktic foram assemblages.
Remotely sensed observations using Landsat time-series from 2013-2023 to determine water savings for riparian corridor sites in the Lower Colorado River Basin affected by tamarisk defoliation Remotely sensed observations using Landsat time-series from 2013-2023 to determine water savings for riparian corridor sites in the Lower Colorado River Basin affected by tamarisk defoliation
These spatial and tabular data were compiled to have a decades-long record of the water usage in the riparian corridor for 27 selected sites where tamarisk (Tamarix spp) or saltcedar defoliation was reported by ground observations and/or exhibited in Google Imagery at locations across the Lower Colorado River Basin. Data for these sites was measured remotely for plant health as...
Greater Sage-grouse and Common Raven Demographic and Count Data Before and After Egg-oiling Treatments of Raven Nests at Control and Treatment Sites Greater Sage-grouse and Common Raven Demographic and Count Data Before and After Egg-oiling Treatments of Raven Nests at Control and Treatment Sites
These data contain field and analytical data used to evaluate the effects of applying non‑toxic oil to common raven (Corvus corax) eggs on both raven reproductive success and demographic responses of co‑occurring greater sage-grouse (Centrocercus urophasianus) populations across sagebrush ecosystems in Nevada and California. Data include: (1) Raven nest monitoring data (nest locations...
Effects of vegetation and soils surface disturbance and reclamation on invasive annual grasses: an annotated bibliography to inform environmental effects analyses related to oil and gas development Effects of vegetation and soils surface disturbance and reclamation on invasive annual grasses: an annotated bibliography to inform environmental effects analyses related to oil and gas development
This data release includes citation details, abstracts, and results of a semi-automated content analysis for 171 publications we identified on the topic of the potential effects of vegetation and soils surface disturbance and reclamation associated with oil and gas development on invasive annual grass establishment and spread. Our goal was to develop a structured literature search and...

Underwater Audio Data Collected in the Upper Colorado River, Colorado, 2021-24 Underwater Audio Data Collected in the Upper Colorado River, Colorado, 2021-24
This data release contains audio data collected from 2021 to 2024, expanding on the dataset collected for a 2019 U.S. Geological Survey (USGS) study which tested the use of hydrophones to detect bedload mobilization and identify a streamflow threshold at which bedload began to mobilize in the Upper Colorado River (Kohn and others, 2020). Child item "Stationary Hydrophone Data collected...
