Decision model simulation of the reintroduction of bull trout in the upper Lake Chelan basin, Washington Decision model simulation of the reintroduction of bull trout in the upper Lake Chelan basin, Washington
The feasibility of a potential bull trout (Salvelinus confluentus) reintroduction was simulated across 12 streams and river segments in the upper Lake Chelan basin using a population matrix model. The model considered habitat availability, life history expression, and assumptions regarding constraints on potential bull trout populations. Details of the simulation framework are described...
Dedicated Dredging on the Barataria Basin Landbridge (BA-36): 2018 and 2021 land-water classifications Dedicated Dredging on the Barataria Basin Landbridge (BA-36): 2018 and 2021 land-water classifications
The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create and enhance Louisiana's coastal wetlands. The wetland restoration plans developed pursuant to these acts specifically require an evaluation of the effectiveness of each coastal wetlands restoration project in achieving long-term solutions to...
Deep learning classification of landforms from lidar-derived elevation models in the glaciated portion of the northern Delaware River Basin of New Jersey, New York, and Pennsylvania Deep learning classification of landforms from lidar-derived elevation models in the glaciated portion of the northern Delaware River Basin of New Jersey, New York, and Pennsylvania
The Delaware River Basin (DRB) covers portions of five states (Delaware, Maryland, New Jersey, New York, and Pennsylvania) and several geologic provinces, encompassing much of the complex geology of the Mid-Atlantic region. This data release focuses on the recently glaciated northern DRB, which includes portions of New Jersey, New York, and Pennsylvania. Groundwater storage is...
Deep SEARCH eDNA metabarcoding data Deep SEARCH eDNA metabarcoding data
The Deep SEARCH Project (Deep sea exploration to advance research on cold corals/canyon/cold seep habitats) included a cruise in April 2019 aboard the NOAA ship Ron Brown to various sites along the Mid-Atlantic North American coast. An ROV was used to collect samples of bottom water at these sites, which were then subjected to eDNA extraction and analyses. This data release describes...
Delaware River Basin depth to bedrock observations, model predictions, and explanatory variables Delaware River Basin depth to bedrock observations, model predictions, and explanatory variables
This data release contains model inputs, R code, and model outputs for predicting depth to bedrock in the Delaware River Basin at a 1km gridded resolution with a random forest model. Model inputs are provided in a comma-separated value (csv) file. The training data used in this study of 72,773 point observations of depth to bedrock (DTB) within the Delaware River Basin (DRB) that was...
Delaware River Basin Stream Salinity Machine Learning Models and Data Delaware River Basin Stream Salinity Machine Learning Models and Data
This model archive contains the input data, model code, and model outputs for machine learning models that predict daily non-tidal stream salinity (specific conductance) for a network of 459 modeled stream segments across the Delaware River Basin (DRB) from 1984-09-30 to 2021-12-31. There are a total of twelve models from combinations of two machine learning models (Random Forest and...
Delmarva Peninsula Stream Health and Habitat Assessments in Maryland and Delaware (2022) (ver. 2.0, April 2025) Delmarva Peninsula Stream Health and Habitat Assessments in Maryland and Delaware (2022) (ver. 2.0, April 2025)
U. S. Geological Survey (USGS) scientists completed a data collection campaign from the 25th of April to the 10th of June in 2022, using various methods to record geomorphic and habitat indicators throughout 30 streams on the Delmarva Peninsula. Field methods included GNSS surveys, gravelometer-based pebble count readings, visual assessments, and riparian analyses. This metadata record...

Demographic Measurements to Inform a Brood Translocation Integrated Population Model Demographic Measurements to Inform a Brood Translocation Integrated Population Model
Wildlife managers translocate greater sage-grouse (Centrocercus urophasianus; sage-grouse) to augment small populations, but translocated sage-grouse often fail to reproduce post-release, sometimes hampering conservation objectives. We performed two distinct sage-grouse translocation projects in California and North Dakota from 2017-2020 and employed two translocation methods at both...
