Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Catch and Effort Data for Cisco and Lake Whitefish Commercial Gill Net Fisheries in State of Michigan Waters of Lakes Superior, Michigan, and Huron During 1929-1970 Catch and Effort Data for Cisco and Lake Whitefish Commercial Gill Net Fisheries in State of Michigan Waters of Lakes Superior, Michigan, and Huron During 1929-1970
This data release presents catch and effort data for Cisco Coregonus artedi and Lake Whitefish Coregonus clupeaformis commercial gill net fisheries in State of Michigan waters of Lakes Superior, Michigan, and Huron during 1929-1970. The data were used to determine if Cisco and Lake Whitefish relative abundance (commercial gill net catch per effort) were correlated (positive and negative)...
Idealized COAWST numerical model for testing marsh wave thrust and lateral retreat dynamics routines Idealized COAWST numerical model for testing marsh wave thrust and lateral retreat dynamics routines
There are two idealized domains developed in this work to test the marsh dynamics in the COAWST modeling framework. 1. First idealized domain is to test and verify the lateral thrust calculations. 2. Second idealized domain is to test the implementation of lateral retreat formulations.
COAWST model of Barnegat Bay creeks to demonstrate marsh dynamics COAWST model of Barnegat Bay creeks to demonstrate marsh dynamics
The COAWST (Coupled Ocean-Atmosphere-Wave-Sediment Transport) modeling framework was extended to add two key processes that affect marshes, erosion due to lateral wave thrust (LWT) and vertical accretion due to biomass productivity. The testing of the combined effects of integrating these two processes was done by modeling marsh complexes within Forsythe National Wildlife Refuge and the...
Random forest regression model and prediction rasters of fluoride in groundwater in basin-fill aquifers of western United States Random forest regression model and prediction rasters of fluoride in groundwater in basin-fill aquifers of western United States
A random forest regression (RFR) model was developed to predict groundwater fluoride concentrations in four western United Stated principal aquifers - California Coastal basin-fill aquifers, Central Valley aquifer system, Basin and Range basin-fill aquifers, and the Rio Grande aquifer system. The selected basin-fill aquifers are a vital resource for drinking-water supplies. The RFR model...
Favorability of environmental conditions for coral reefs in Guam and American Samoa under multiple climate scenarios Favorability of environmental conditions for coral reefs in Guam and American Samoa under multiple climate scenarios
This dataset consists of raster geotiff outputs of relative environmental favorability for coral growth and survival in the United States territories of Guam and American Samoa across 3 climate scenarios: Present, Intermediate Emissions (Representative Concentration Pathway 4.5), and Worst Case Emissions (Representative Concentration Pathway 4.5). These datasets were generated from a...
Total organic carbon and pyrolysis analysis data for the U.S. Geological Survey Alcova AR-1-13 core hole, Natrona County, Wyoming Total organic carbon and pyrolysis analysis data for the U.S. Geological Survey Alcova AR-1-13 core hole, Natrona County, Wyoming
In 2013 the U.S. Geological Survey (USGS) drilled a continuous core in the southeastern part of the Wind River Basin, Wyoming to evaluate the source rock potential of the Lower and lowermost Upper Cretaceous marine shales . The well, named the Alcova Reservoir AR-1-13, located on the northeast flank of the Alcova anticline was spud in the lower part of the Frontier Formation and ended in...
