Louisiana Barrier Island Comprehensive Monitoring Program – 1996-2005 general habitat maps, West Chenier Plain, Early Lafourche Delta, Late Lafourche Delta, Modern Delta, Chandeleur Islands Regions

This data release includes data from 1996-2005 for the Louisiana Barrier Island Comprehensive Monitoring Program. Specifically, this data release includes general habitat maps for West Chenier Plain, Early Lafourche Delta, Late Lafourche Delta, Modern Delta, Chandeleur Islands Regions. Please consult the accompanying readME.txt file for information and recommendations on the contents of this datas

Survey of potential viral pathogens in the ceca of pen-raised mallards

The threat posed by infectious diseases are a major concern for global public health and the role of migratory birds in pathogen transmission is increasingly under scrutiny. Enteric viral pathogen surveillance in migratory birds is a critical component of outbreak preparedness. The shedding of such pathogens through excrement into bodies of water located at migratory stop-over sites and breeding a

Multichannel minisparker and chirp seismic reflection data collected during USGS field activity 2021-614-FA along the Palos Verdes Fault Zone

High-resolution multichannel seismic (MCS) and coincident Chirp sub-bottom data were acquired during USGS field activity 2021-614-FA aboard the R/V Sproul in May of 2021. The survey was conducted in the offshore region of southern California, specifically in the inner continental borderlands tectonic region. The focus of the survey was to collect seismic lines perpendicular to the Palos Verdes Fau

MODFLOW-2005 and SWI2 models for assessing groundwater and surface-water interactions in the Heeia Watershed, Oahu, Hawaii

Resource managers and users seek information that can be used to balance the needs of competing uses of groundwater and streamflow in the Heeia watershed, Oahu. A previously constructed steady-state numerical groundwater-flow model for the island of Oahu, Hawaii ( using MODFLOW-2005 with the Seawater Intrusion (SWI2) package was used to examine the effects of wi

Statistical and groundwater-flow models of the Fountain Creek alluvial aquifer near Colorado Springs, Colorado

The U.S. Geological Survey (USGS), in cooperation with the Air Force Civil Engineering Center, created a numerical groundwater-flow model for the Fountain Creek alluvial aquifer using the finite-difference MODFLOW code with the Newton formulation solver. This numerical groundwater-flow model simulates water-budget components, groundwater-flow directions, and groundwater-flow paths of the Fountain

Data and Code Release: Determination of Larval Sea Lamprey (Petromyzon marinus) Seasonal Sensitivity Differences to Lampricide Treatment

Controlling larval sea lamprey (Petromyzon marinus) in Great Lakes tributaries with 4-nitro-3-(trifluoromethyl)phenol (TFM, a pesticide) stream treatments reduces the number of spawning-phase sea lamprey, an invasive species capable of collapsing Great Lakes fisheries. An important component of stream treatments is ensuring that the proper amount of TFM is applied that will effectively control sea

Water Temperature, Electrical Conductivity, and Salinity of Lagoons in the Beaufort Sea, Alaska, 2017-2019

This dataset contains a table with temperature (°C), raw electrical conductivity (μS/cm), and salinity (psu) measured in Beaufort Sea, Alaska, Lagoons during summers 2017-2019.

Fish sampling data in La Grange Pool of the Illinois River during 2015 to determine largemouth bass and silver carp population size structure and size-selective largemouth bass piscivory

Dataset contains sampling information (site, location, and date of sampling) for largemouth bass and silver carp captured in La Grange Pool of the Illinois River during 2015 used to determine the population size structure of both species for analyzing size-specific feeding of largemouth bass on young-of-year and Age-1 silver carp. The dataset also contains information on fish prey items found in l

Catalogue of the literature assessing climate effects on ungulates in North America (1947-2020)

This dataset contains information from 674 publications (academic and grey literature) that assessed the effects of climate variability and climate change on the 15 ungulate species that are native to the United States, Canada, Mexico, and Greenland. The publication contains literature published between 1947 and September 2020. Information documented includes study location, climate variables asse

Sediment chemistry data from sediment traps deployed in the San Juan River watershed, 2021-2022, Four Corners USA

Sediment traps were deployed in thirty-three ephemeral and perennial tributaries to the San Juan River during 2021 and 2022. This dataset includes the chemical concentrations of the sediment samples collected in sediment traps during storm events. These traps collected sediment during storm events that typically occur as monsoonal convective storms from June to September. Because of the rural natu

Coastal Bathymetry and Backscatter Data Collected in May 2023 From Rockaway Peninsula, New York

Scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS – SPCSMC), conducted a nearshore geophysical survey offshore of the Rockaway Peninsula, New York (NY), during May 2023. Multibeam bathymetry and acoustic backscatter data were collected aboard the research vessel (R/V) Sallenger. The survey was supported by the National Fish and Wildlife Foundation (N
