Carbon Dioxide Storage Resources - Appalachian Basin, Black Warrior Basin, Illinois Basin, and Michigan Basin: Chapter P, Spatial Data

The storage assessment unit (SAU) is the fundamental unit used in the National Assessment of Geologic Carbon Dioxide Storage Resources project for the assessment of geologic CO2 storage resources. The SAU is shown here as a geographic boundary interpreted, defined, and mapped by the geologist responsible for the assessment interval. Individual SAUs are defined on the basis of common geologic and h

Mercury in biota from Clear Lake, California (ver. 3.0, August 2024)

Comma-separated values (.csv) file containing data related to mercury in biota collected from Clear Lake, California. This data release supersedes Pierce, J.R., Feyrer, F., Young, M., Enos, E., Clause, J., Alpers, C., and Eagles-Smith, C.A., 2022, Mercury in fishes from Clear Lake, California, 2019 and 2020 (ver. 2.0, February 2022): U.S. Geological Survey data release, https://doi.org/10.5066/P9

Demographic, morphometric, and meristic data describing cisco (Coregonus artedi) captured in the Spanish River, Ontario, Canada, 15-16 November 2022

These data describe demographic (e.g, age), morphometric (body shape), and meristic (total number of gill rakers) measurements of a probable spawning run of cisco (Coregonus artedi) collected from the Spanish River (Ontario, Canada) immediately downstream of the Espanola Dam from 15-16 November 2022. These data were used to provide baseline biological, demographic, and morphological information on

Mississippi River fishes collected by a suite of entanglement and entrapment gears; 2020-2023

Black Carp (Mylopharyngodon piceus) were imported to the United States for use as a biological control in aquaculture and have since escaped with reproducing populations in the wild. Habitat use and capture of this species has not been well documented in the wild, thus questions about catchability by gears and habitats are present. This dataset represents sampling effort to capture Black Carp with

Hydroacoustic data from uncrewed surface vehicle (USV) overtakes in Lake Superior, 2022

These data were derived from hydroacoustic data collected by uncrewed surface vehicles (USVs) and powered research vessels in Lake Superior in 2022. The powered vessels overtook the USVs to study fish avoidance of survey vessels during traditional acoustic surveys. The water column was divided into four depth groups for analysis. Each USV transect was binned into 30-sec intervals and measured hydr

Evaluation of fish behaviors in response to driven and undriven entanglement nets with emphasis on invasive Silver Carp, Central Missouri, 2015-2016

We used Adaptive Resolution Imaging Sonar (ARIS), which is based on Dual-Frequency Identification Sonar (DIDSON) technology to observe net encounter behaviors of bigheaded carps. Gill nets with four different mesh types (8.9 cm bar mesh) and trammel nets with five different mesh sizes (range 5.1-8.9 cm bar mesh) were evaluated. Net sets were undisturbed, or fish were driven with the noise of the o

Historical (2001-2013) and End-of-Century Future Climate Simulated Snowpack and Hydrometeorology for the Gallatin River, Montana and Wyoming

This data release contains output from a numerical snow simulation for a 65 kilometer (km) × 81 km model domain in parts of Montana and Wyoming, United States, encompassing the Gallatin River watershed upstream of the U.S. Geological Survey streamgage near Gallatin Gateway, MT (06043500). Weather Research and Forecasting (WRF) Model convection-permitting and orography-resolving regional climate si

Satellite-derived shorelines for the U.S. Gulf Coast states of Texas, Louisiana, Mississippi, and Florida for the period 1984-2022, obtained using CoastSat

This dataset contains shoreline positions derived from available Landsat satellite imagery for four states (Texas, Louisiana, Mississippi, and Florida) along the U.S. Gulf coast for the time period 1984 to 2022. An open-source toolbox, CoastSat (Vos and others, 2019a and 2019b), was used to classify coastal Landsat imagery and detect shorelines at the sub-pixel scale. Resulting shorelines are pres

Black Carp in North America: a description of range, habitats, date, and methods of reported captures May 2018-October 2022

Black Carp collections (n=534) by commercial fishers, biologists, and recreational anglers from the Mississippi River basin recorded from 2018 to 2022 are reported here. Geographic coordinates, total length (TL), weight, girth, date of capture, sex, and gear were recorded. Total length was measured from the tip of the snout to the longest caudal fin ray with the caudal fin lobes pinched. Girth was

Digital database of a 3D Geological Model of western South Dakota

This digital GIS dataset and accompanying nonspatial files synthesize the model outputs from a regional-scale volumetric 3-D geologic model that portrays the generalized subsurface geology of western South Dakota from a wide variety of input data sources.The study area includes all of western South Dakota from west of the Missouri River to the Black Hills uplift and Wyoming border. The model data

Northern Lake Michigan lake trout (Salvelinus namaycush) and burbot (Lota lota) diet data, 2021-2023

These data consist of lake trout and burbot diet information collected from USGS spring and fall gillnet surveys in Northern Lake Michigan from 2021-2023. All prey were identified, enumerated and weighed. Only fish prey had lengths measured.

Remote sensing and field data supporting the analysis of Maryland winter cover crop performance, 2019-2021

This data release includes winter cover crop field sampling data (2006-2021) collected from Maryland farms, along with two seasons of Maryland cost-share program field enrollment data (2019-20 and 2020-21) and associated satellite-derived vegetation index values, supporting the remote sensing analysis of winter cover crop environmental performance on fields receiving incentive payments.
