Genetic Data Used to Develop a Genotyping-in-Thousands by Sequencing (GT-seq) Panel for Identifying Individuals and Estimating Relatedness in Alaska Black Bears (Ursus americanus) Genetic Data Used to Develop a Genotyping-in-Thousands by Sequencing (GT-seq) Panel for Identifying Individuals and Estimating Relatedness in Alaska Black Bears (Ursus americanus)
This data package includes genotype data for two independent sets of American black bear (Ursus americanus) samples. The first set of samples was collected from 85 adult bears harvested by permitted hunters in southcentral Alaska from 1994-2019; we hereafter refer to these as "hunter-harvested" samples. These hunter-harvested samples were genotyped with restriction site-associated...
Data Release: Insect pollinator crossing of international border barriers along the U.S.-Mexico border, March 2023-January 2024 Data Release: Insect pollinator crossing of international border barriers along the U.S.-Mexico border, March 2023-January 2024
The data release records observations of insect crossing in the Lower Rio Grande National Wildlife Refuge along the U.S.-Mexico Border from 20230307 to 20240125. The barrier appears to be a partial barrier to some types of pollinators attempting to cross during high wind.

Tiltmeter data from Kīlauea stations (ESC, IKI, JKA, KAE, POC, SDH, SMC, UWE) from January 1 to December 31, 2023. These data were collected in 2023 by Andria P. Ellis of the USGS Hawaiian Volcano Observatory.
U.S. Geological Survey simulations of hydrodynamics and morphodynamics during Hurricane Michael (2018) U.S. Geological Survey simulations of hydrodynamics and morphodynamics during Hurricane Michael (2018)
The Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST v3.8; Warner and others, 2010; Warner and others, 2019) modeling system was used to simulate ocean circulation, water levels, waves, and sediment transport that occurred during Hurricane Michael (2018). Simulations were performed with coupled and concurrent ocean and wave models simulated on a series of refined, cascading grids...

This dataset describes mercury (Hg) and methylmercury (MeHg) concentration data and Hg and MeHg stable isotope values in plankton, waters, and sediments that were collected from two inland freshwater lakes in Madison, Wisconsin. Plankton and waters were collected monthly from May-October in 2021 and 2022 from Lake Mendota and Lake Monona and sediments were sampled in 2017. Samples were...
Round goby detection by scuba divers’ visual assessments and environmental DNA in the Great Lakes, 2022 Round goby detection by scuba divers’ visual assessments and environmental DNA in the Great Lakes, 2022
This dataset is associated with an examination of environmental DNA (eDNA) from the invasive round goby (Neogobius melanostomus) in parallel with visual surveys of fish count and size conducted by scuba divers in four Great Lakes: Michigan, Huron, Erie, and Ontario. Round goby inhabits benthic areas, and it is known to have direct contact with the bottom substrate as it feeds on...
