Floodplain inundation is believed to be the dominant physical driver of an array of ecosystem patterns and processes in the Upper Mississippi River System (UMRS). Here, we present results of a change analysis to estimate shifts in floodplain inundation regime characteristics from 1940 to 2022 in navigation pools 3 through 10 along the Upper Mississippi River. Data were derived from a...

This dataset includes bluegill age data from five study reaches of the Mississippi River and one study reach from the Illinois River as presented in the manuscript Big River Bluegill: Combining vital rates and long-term monitoring to understand population dynamics in large rivers. Any use of trade, firm, or product names is for descriptive purposes only and does not imply endorsement by...

Flows at Fort Peck Dam, Montana, were modified in 2024 to include additions of warm epilimnetic reservoir releases over the spillway of the dam as part of a series of flow tests to improve habitat conditions in the Upper Missouri River for pallid sturgeon (Scaphirhynchus albus). We measured velocity and discharge on June 22 and June 23 in the Upper Missouri River and Fort Peck Dam...

This USGS data release consists of five data sets and accompanying metadata for an experimental mark-release-recapture (MMR) study of adult Culex quinquefasciatus conducted in a montane rainforest in Upper Waiākea Forest Reserve on the Island of Hawai'i from October-December 2020 and laboratory survivorship studies and analysis from 2021- 2024. Culex quinquefasciatus is the vector of the...

In the San Luis Obispo Bay area of central California, interpretations of marine terrace ages have been hampered by inconsistent results from geochronological indicators (U-series ages of corals and correlations using amino acid racemization of mollusks) and seemingly contradictory paleozoogeographic aspects of fossil faunal assemblages. The two lowest-elevation terraces are Q1 (lower)...

This data release includes uranium-lead isotopic data collected from metaplutonic rocks of the New Hampshire Plutonic Suite and metasedimentary rocks of the New Hampshire Sequence. Rock samples were collected by Arthur Merschat, Greg Walsh, and Ryan McAleer. Samples were processed and analyzed by Arthur Merschat and Ryan McAleer. Uranium-lead isotopic data was collected using a sensitive...

Emergent marine terraces record past periods of relatively high sea level and are common on uplifting coasts worldwide. Such landforms are extensive around the Gulf of Corinth area of Greece and along the coast of California, USA. In the Gulf of Corinth region, marine terraces record Quaternary uplift due to ongoing basin extension on the northern side of the Africa-Eurasia-Aegean Sea...

This metadata record documents one comma delimited table that contains information on the grain size distribution, fallout radionuclide activity, and geochemical characteristics of urban sediments within the Hickey Run watershed in Washington, D.C. Measurements include radiological activity, sediment particle size information, and elemental composition of source and target sediments.

A new 30 meter resolution polygon data layer of the islands of the United States, with associated attributes describing key physical and conservation geography characteristics. Islands were grouped into a three-tiered hierarchy of island provinces (12), island regions (28), and individual islands (a total of 19,023 islands were extracted). Islands were classified as estuarine vs non...

This data release includes aerial photos taken from a small aircraft for reconnaissance purposes (Figure 1). The photos were taken from several different types of cameras ranging from iPhones to Cannon EOS6. Camera attributes can be found in the exif data associated with each file. Photos were taken over a period of 3 days (3-5 October, 2024) to obtain general situational awareness of...

Two digital video cameras were installed at Dorado, Puerto Rico (PR); camera 1 faced west alongshore and camera 2 faced northeast alongshore. Every hour during daylight hours, daily starting in August 2022, the cameras collected raw video and produced snapshots and time-averaged image products. This data release includes the necessary intrinsic orientation (IO) and extrinsic orientation...

Two digital video cameras were installed at Isla Verde, Puerto Rico (PR); camera 1 faced northeast offshore and camera 2 faced east-northeast along the beach. Every hour during daylight hours, daily starting in August 2022, the cameras collected raw video and produced snapshots and time-averaged image products. This data release includes the necessary intrinsic orientation (IO) and...
