Data Releases

This dataset contains canopy measurements of Taxodium distichum taken outside of the Wetland and Aquatic Research Center in Lafayette, Louisiana. The measurements were used to produce data on tree canopy area and seeds produced per Taxodium distichum tree.

This dataset is part of a population model of Buttonland Swamp in the Cache River Watershed of Illinois. The modeling spans three decades of data from 1990 to 2021. This dataset is used to compare regeneration of Taxodium distichum along a moisture gradient of drier to wetter: Section 8 Woods (2006-2011), Crawford Tract mid-elevation, Eagle Pond, Deer Pond, Wildcat Bluff, Snake Hole...

This dataset contains tree health information in 2022 for ten trees in Buttonland Swamp, part of the Cache River Watershed in Illinois. The data includes the height of the trees along with their crown ratio. This allows an understanding of the size and canopy health of Buttonland Swamp cypress trees. A Munsell color chart was utilized in determining leaf color. Leaf color tells whether...

This dataset represents annual reproductive litterfall collections and seedling data from Crawford Tract, Eagle Pond, Section 8 Woods, Deer Pond, Wildcat Bluff, Snake Hole, and Heron Pond from 2006 to 2021. These sites are part of the study location, Buttonland Swamp, within the Cache River Watershed, Illinois. Summer and winter water depths were also included in the dataset.

This U.S. Geological Survey (USGS) data release provides zooplankton data collected from Cheney Reservoir, Kansas, during October 2008 through October 2022. All data are reported as raw calculated values and are not rounded to USGS significant figures. This data release was produced in compliance with the open data requirements as a way to make scientific products associated with USGS...

This U.S. Geological Survey (USGS) Data Release provides phytoplankton data collected from Cheney Reservoir, Kansas, during June 2001 through October 2022. All data are reported as raw calculated values and are not rounded to USGS significant figures. This data release was produced in compliance with the open data requirements as a way to make scientific products associated with USGS...

The United States Large-Scale Solar Photovoltaic Database (USPVDB) provides the locations and array boundaries of U.S. ground-mounted photovoltaic (PV) facilities with capacity of 1 megawatt or more. It includes corresponding PV facility information, including panel type, site type, and initial year of operation. The creation of this database was jointly funded by the U.S. Department of...

This set of data files contains analyses of samples representing Triassic units (Shublik and Ivishak Formations and Karen Creek Sandstone) in Alaska. The samples were collected from 20 outcrop localities in northeastern Alaska. The data set includes total organic carbon (TOC) and geochemical data from inductively coupled plasma-optical emission spectroscopy-mass spectroscopy (ICP-OES-MS)...

The U.S. Geological Survey (USGS) 3D Elevation Program (3DEP) has initiated the development of a second pilot 3D National Topography Model (3DNTM) to generate 3-dimensional surface elevation models that integrate topographic bare-earth elevation surfaces with river channel bed and coastal bathymetry and topobathymetry. Detailed knowledge of integrated river system topography, bathymetry...

This data release provides avian data for 11 songbird species (Bewick’s wren [Thryomanes bewickii], black-throated gray warbler [Setophaga nigrescens], Brewer’s sparrow [Spizella breweri], gray flycatcher [Empidonax wrightii], gray vireo [Vireo vicinior], green-tailed towhee [Pipilo chlorurus], juniper titmouse [Baeolophus ridgwayi], loggerhead shrike [Lanius ludovicianus], sagebrush...

This data release includes water quality and zooplankton data collected from ponds on Boudin Island in the Sacramento-San Joaquin Delta. Data were collected in the Bouldin East and Bouldin West ponds concurrently with a Delta Smelt Deployment Experiment which involved three cages in each pond with approximately 60 Delta Smelt (Hypomesus transpacificus) in each cage. There were two fish...

The USGS CAWSC Organic Matter Research Laboratory (OMRL) provides laboratory services and support to regional and national projects in the analysis of organic matter using the latest methods in absorbance and fluorescence spectroscopy. Optical measurements such as absorbance and fluorescence are used to gain insight into dissolved organic matter (DOM) composition, and can also serve as...
