Forest biomass projections under alternative management and hydrological scenarios in the Reno Bottoms area of the Upper Mississippi River floodplain Forest biomass projections under alternative management and hydrological scenarios in the Reno Bottoms area of the Upper Mississippi River floodplain
Floodplain forests are being transformed by multiple pressures, prompting widespread management and restoration efforts. It is uncertain how disturbances, including hydrologic change, and management actions will interact to influence the ecology of these threatened forests. Here, we present the results of a forest landscape model in support of an ecological study detailed in the...
USGS National and Global Oil and Gas Assessment Project—North Cuba Area: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project—North Cuba Area: Assessment Unit Boundaries, Assessment Input Data, and Fact Sheet Data Tables
This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in the North Cuba area. The assessment unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources. The assessment unit...
Spatial distribution of native freshwater mussels across six reaches of the upper Mississippi River, 2006-2019 Spatial distribution of native freshwater mussels across six reaches of the upper Mississippi River, 2006-2019
We conducted large-scale systematic surveys for native mussels across six reaches of the upper Mississippi River. In each reach, divers placed two 0.25 square meter quadrat frames on the river bottom. The duplicate quadrats, which were placed 10 m apart in an upstream to downstream direction, were used to increase the area sampled at each site and increase the effectiveness of this...
Simulation of Groundwater Flow in the Long Island, New York Regional Aquifer System for 2010 Daily Recharge Conditions Simulation of Groundwater Flow in the Long Island, New York Regional Aquifer System for 2010 Daily Recharge Conditions
This model archive documents a transient groundwater-flow model that simulates hydrologic conditions in the Long Island aquifer system for the year 2010, using the U.S. Geological Survey groundwater modeling software MODFLOW 6 (Langevin and others, 2017). The groundwater model is a derivative of the conditioned model documented in Jahn and others (2024), and described in Walter and...
Sediment Data From Surface Samples and Sand Augers Collected in 2023 From the Northern Chandeleur Islands, Louisiana Sediment Data From Surface Samples and Sand Augers Collected in 2023 From the Northern Chandeleur Islands, Louisiana
In 2023, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) conducted a sediment sampling survey at the northern Chandeleur Islands, Louisiana. Funded by the Extending Government Funding and Delivering Emergency Assistance Act (Public Law 117-43) enacted on September 30, 2021, these data complement sediment data from samples...
Nuisance algae: Planktonic communities in the Grand Calumet River Area of Concern, Indiana, 2021 Nuisance algae: Planktonic communities in the Grand Calumet River Area of Concern, Indiana, 2021
The data being released were part of a project funded by the United States Environmental Protection Agency (USEPA). This study sought to identify the bacterial and planktonic communities (cyanobacteria, eukaryotic algae) potentially contributing to eutrophication within the Grand Calumet River Area of Concern (AOC) in northern Indiana along the southern shore of Lake Michigan. In 2021...
