This data release presents chemical results from investigations of surface-water quality in the Potomac River watershed (encompassing Washington, D.C. and parts of West Virginia, Virginia, Pennsylvania, and Maryland) conducted during low-flow conditions in July through September of 2022 and modeling results that support interpretative products. Water-quality sampling: A sampling campaign...
Chesapeake Bay Tidal Shoreline, Chesapeake Bay Program Phase 7 Model Chesapeake Bay Tidal Shoreline, Chesapeake Bay Program Phase 7 Model
This polygon dataset represents the tidal water shoreline of the Chesapeake Bay and its tributaries. It is based primarily on shoreline data with horizontal positional accuracy of +/- 2meters provided by the Virginia Institute of Marine Science (VIMS) Center for Coastal Resources Management (CCRM), with minor modifications in seven locations. In six instances, the modifications were made...
Experiences of experts in managing and researching chronic wasting disease obtained through 2023 semi-structured interviews Experiences of experts in managing and researching chronic wasting disease obtained through 2023 semi-structured interviews
The provided dataset is the coded analysis of qualitative semi-structured interviews conducted with managers and researchers who are experts on chronic wasting disease (CWD). CWD is a transmissible spongiform encephalopathy disease that affects species in the Cervidae family. CWD has also proven difficult to manage and the disease continues to spread across North America and parts of...
Aquifer framework datasets used to represent the Pecos River Basin alluvial aquifer, Texas, New Mexico Aquifer framework datasets used to represent the Pecos River Basin alluvial aquifer, Texas, New Mexico
The Pecos River Basin alluvial aquifer, hereinafter referred to as the "Pecos aquifer", is located in western Texas and southeastern New Mexico. The aquifer is primarily composed of alluvial sand and gravel deposits mantled by sand and silt. The Pecos aquifer overlies Permian, Triassic, and Cretaceous-age rocks. The saturated thickness of the aquifer ranges from 0 to 1000 feet. The...
Laboratory Observations of Oscillatory Flow Over Sand Ripples Laboratory Observations of Oscillatory Flow Over Sand Ripples
These datasets comprise of laboratory observations of oscillatory flows over mobile sand ripples. The data were collected in the Small-Oscillatory Flow Tunnel (S-OFT) in the Sediment Dynamics Laboratory at the U.S. Naval Research Laboratory, Stennis Space Center, Mississippi (MS), while Donya Frank-Gilchrist was a National Research Council post-doctoral fellow there. The flow tunnel has...
Code and data from Castro-Santos et al.: Sprinting performance and behavior of shortnose sturgeon Code and data from Castro-Santos et al.: Sprinting performance and behavior of shortnose sturgeon
This data release includes the raw data and code used in Castro-Santos et al. (2024): Sprinting performance and behavior of adult shortnose sturgeon (Acipenser brevirostrum). Notably, the code includes several processes used to differentiate among attempts, quantify attempt rate, distance traversed, and endurance of shortnose sturgeon ascending a telemetered flume. The code can be...
Prefabricated Zero Ascend Omnispecies (ZAO) Modular Fish Passage Modules Using Advanced Manufacturing Techniques Prefabricated Zero Ascend Omnispecies (ZAO) Modular Fish Passage Modules Using Advanced Manufacturing Techniques
In this dataset, there are eight text files that provide the raw fish behavior telemetry data and an excel sheet that provides the processed velocity data.
Detecting trajectories of regime shifts and loss of resilience in coastal wetlands using remote sensing Detecting trajectories of regime shifts and loss of resilience in coastal wetlands using remote sensing
Raster data shows landscape scale trajectories of change as four potential scenarios based on Normalized Difference Vegetation Index (NDVI) trends and standard deviation trends using full time series (Scenarios_All_FULL_TS.tif) as well as time series up to LandTrendr breakpoint if detected (Scenarios_All_LT_TS.tif). Time series analysis for trend use Landsat surface reflectance imagery...
