These data represent two years of trapping effort for invasive black and white tegu lizards (Salvator merianae) in South Florida. Over the course of the two years, traps were deployed in the same locations, but the type of bait in the trap varied. Bait treatment types consisted of a single real chicken egg (traditionally used in the past), 3 real eggs, 3 fake wooden eggs, 2 fake wooden...

The U.S. Geological Survey Upper Midwest Water Science Center, in cooperation with the U.S. Coast Guard Great Lakes Oil Spill Center of Expertise and the Mashkiiziibii Natural Resources Department, completed bathymetric surveys of the lower Bad River, Kakagon River, Honest John Lake, and the Bad River Slough using multibeam and single beam echosounders from April 29 to May 1, 2025. This...

Ground Penetrating Radar (GPR) surveys were conducted within the San Francisco Volcanic Field (SFVF) in Northern Arizona from October 8th-15th in 2016 and August 4th-8th in 2023. These surveys collected GPR data using variable antenna frequencies and survey styles in varied geologic terrains. The main focus of this data collection was on volcanic terrains in the SFVF, including lava...

Ontogenetic niche shifts are almost universal in fishes and many other organisms and are thus often important to factor in conservation planning. However, some aspects of ontogeny, such as trophic shifts, remain poorly understood in many fishes. Eye lens stable isotope analysis has proven a powerful tool in understanding the ontogeny of some marine species, but few studies have applied...

Eastern oyster (Crassostrea virginica) produced in a hatchery were maintained in cages at multiple sites in coastal Louisiana, and shell height, mortality, fecundity, and dermo were monitored to compare performance between genomically selected groups. Oysters were produced using genomic selection techniques targeting low-salinity tolerant oysters (high breeding value). To test...

This Model Archive Summary (MAS) describes the development of a turbidity derived suspended-sediment concentration (SSC) time-series computation model. The MAS includes all the methods and techniques used to develop the model for USGS station 11313315 Old River Near Byron, California. The time-series suspended-sediment concentration data are representative of the cross section and are...

This U.S. Geological Survey data release presents monthly evaporation estimates from Lake Mead, Nevada and Arizona, for January 2021 through December 2023. The spreadsheet includes five worksheets: (1) Read_Me worksheet contains information relevant to understanding the data contained in the rest of the worksheets. (2) Monthly_EC_Met worksheet includes data measured at a land-based...

The Corps of Engineers' Rock Island District is planning an unprecedented closure of the Illinois Waterway in 2020 in order to perform required maintenance on locks. Aerial imagery will document river conditions prior to the closure (2019) and after the locks are reopened (2021). Under a separate but related effort, aerial imagery of the entire Illinois Waterway will be collected in 2020...

The Louisiana State Legislature established the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) to conserve, restore, create and enhance Louisiana's coastal wetlands. Restoration plans developed under CWPPRA require evaluating the effectiveness of each project in achieving long-term solutions to coastal wetlands loss. This data set includes mosaicked aerial photographs...

The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana’s Coastal Protection and Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring Program (SWAMP). The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands...

This U.S. Geological Survey (USGS) data release contains phytoplankton classification and enumeration results from near-surface water samples collected during a nationwide harmful algal bloom (HAB) monitoring effort in partnership with the National Park Service (NPS) Water Resources Division. Samples were collected during the 2021-2024 monitoring seasons from 26 National Parks across the...

The U.S. Geological Survey conducted a study in Milwaukee, Wisconsin, to evaluate the performance of a biofilter designed to treat urban stormwater runoff from a roadway. This data release includes load calculations for total suspended solids, nutrients, major ions, and 12 metals for monitoring that ran from March, 2022 to November, 2024. Loads are reported for both the inlet (USGS site...
