Data

This data release contains photographs and photomicrographs from drill cores and cuttings of pre-Middle Jurassic basement rocks that are buried beneath Coastal Plain sedimentary deposits in Florida. These samples provide rare insights into deeply buried rocks that have no surface exposures and no known exposed correlates. These images were acquired to support the characterization...

Non-native Phragmites australis is one of the most aggressive plant species invading North America and is managed using a suite of conventional approaches (e.g., herbicide, cutting/crushing, flooding, burning). These management actions are resource intensive and differ in effectiveness, largely because there are uncertainties about how the plant responds to treatment given site-specific...

Data represent physical (water quality) and biological (fish, macroinvertebrate, and vegetation community) collections as indicators for Pool 1A and the Maankiki Marsh North and South units at the Shiawassee National Wildlife Refuge in Saginaw, MI, USA. The Maankiki North and South units were recently reconnected to the Shiawassee River in 2018, whereas Pool 1A represents a historically

These data describe water chemistry and fish, macroinvertebrate and vegetation communities within recently restored, historically-restored, and unrestored wetland management units of the Shiawassee National Wildlife Refuge (SNWR; Michigan, USA). Data were collected in 2021 according to protocols and methods described in Conrad et al. 2022. These methods developed through previous years...

These data describe water chemistry and fish, macroinvertebrate and vegetation communities within recently restored, historically-restored, and unrestored wetland management units of the Shiawassee National Wildlife Refuge (SNWR; Michigan, USA). Data were collected in 2022 according to protocols and methods described in Curwin et al. 2023. These methods were developed through previous...

Over 16 days from May 11–27, 1924, there were more than 50 explosions from Halemaʻumaʻu crater at Kīlauea volcano on the Island of Hawaiʻi. These explosions ejected blocks weighing >12,000 kg, as well as extremely fine ash to lapilli size tephra. The greatest thicknesses of tephra were at the summit region of Kīlauea, but some tephra fell on Wood Valley, Pāhala, and Waiʻōhinu to the...

A Lagrangian study was conducted in 2019 that followed two water masses in the Powder River from central Wyoming to southeastern Montana. The study characterized the changes of the in-stream transport of sediment and associated chemical and biological constituents. Depth-integrated water samples (using an isokinetic nozzle) and river bottom sediment samples were collected at six mainstem...

The most common application of neonicotinoid insecticides in agriculture is through the treatment of seeds before planting. Commercially formulated seed treatments are often sold as mixtures of various pesticides, fungicides and other treatments (e.g., plant growth regulators), the effects of which on non-target organisms are not well understood. To address this data gap, we assessed the...

This U.S. Geological Survey (USGS) Data Release includes phytoplankton data collected from four reservoirs in Kansas, during August 2020 through August 2022. All data are reported as raw calculated values and are not rounded to USGS significant figures. The dataset includes all routine and quality assurance/quality control samples collected at twenty-five locations within Marion...

This data release contains phytoplankton identification and enumeration data from the analysis of water samples collected from 18 lakes within the Adirondack Park, New York State. Samples were collected as part of the Adirondack Long-Term Monitoring (ALTM) program (for more information, refer to: New York State Energy Research and Development Authority, 2015). The ALTM has monitored...

This U.S. Geological Survey (USGS) data release provides phytoplankton data collected from the Kansas River and tributaries, during July 2012 through June 2023. 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...

This data release provides phytoplankton identification and enumeration data during an algal bloom at Ash River boat docks on Kabetogama Lake (USGS site ID 482603092511801) collected between September 12 and September 13, 2023. samples were collected every three hours over a 24-hour period at two sites, one at the end of a dock and one on the adjacent shoreline. Two quality assurance...
