Upper Mississippi River Pool 8 Large Wood Sampling Areas for 2023 High-Flow Event Upper Mississippi River Pool 8 Large Wood Sampling Areas for 2023 High-Flow Event
Large wood is an important part of ecosystem functions in rivers around the world, including serving as fish habitat, providing nutrient sources, and contributing to geomorphic processes. This dataset was produced to support the study of large wood dynamics in Pool 8 of the Upper Mississippi River System. The dataset contains 60 polygons located along shoreline of the main channel, side...
Texas Black Bass Observations and Blotchy Bass Syndrome Measurements Collected by the Texas Parks and Wildlife Department, 2011–2023 Texas Black Bass Observations and Blotchy Bass Syndrome Measurements Collected by the Texas Parks and Wildlife Department, 2011–2023
This data release contains quality controlled records of citizen submitted observations of black bass (Micropterus spp.) provided to the Texas Parks and Wildlife Department (TPWD) through public angler reporting programs. TPWD biologists reviewed, standardized, and anonymized these submissions before sharing the dataset with the U.S. Geological Survey for regional analysis of Blotchy...

This data release contains quality-controlled records of angler-submitted observations of black bass (Micropterus spp.) collected through a two-year citizen science initiative using the MyCatch mobile application. The dataset includes verified catch records for largemouth bass and smallmouth bass, with each entry providing information on catch date, time, location (latitude/longitude)...
Georectified mosaic of historical aerial photographs of the Colorado River within the Lake Mead region, Arizona and Nevada, acquired in 1935 Georectified mosaic of historical aerial photographs of the Colorado River within the Lake Mead region, Arizona and Nevada, acquired in 1935
This product is a georectified and tonally balanced image mosaic of aerial photographs collected in February 1935 by the U.S. Soil Conservation Service along the floodplain of the Colorado River in the Lake Mead region of Arizona and Nevada. This dataset was developed to portray the geologic characteristics of the lower Colorado River floodplain and can serve as a resource to help create...
Loggerhead sea turtle single nucleotide polymorphism data for Dry Tortugas National Park, 2008 - 2016 Loggerhead sea turtle single nucleotide polymorphism data for Dry Tortugas National Park, 2008 - 2016
This release contains single nucleotide polymorphism (SNP) data derived from tissue and blood samples collected from 25 loggerhead individuals across nine years from the Dry Tortugas. Data are provided in FASTQ format, a text-based data structure supported by bioinformatics tools.
Aquatic macroinvertebrate assemblage data from side channels of the Upper Mississippi River System, 2021 Aquatic macroinvertebrate assemblage data from side channels of the Upper Mississippi River System, 2021
To understand how aquatic macroinvertebrate assemblages vary among side channels across a large floodplain river ecosystem, we collected macroinvertebrates from 23 side channels distributed across six reaches of the Upper Mississippi River and Illinois River and quantified taxonomic and functional indices. Within this data release, three products are included: 1) site-level environmental...
