Uranium-series geochemistry and geochronology of marine terrace corals, Perachora Peninsula, Greece and San Nicolas Island, California, USA Uranium-series geochemistry and geochronology of marine terrace corals, Perachora Peninsula, Greece and San Nicolas Island, California, USA
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...
Discharge measurements, air temperature, water temperature, and gage height data for select streams in Maryland-Washington, DC-Virginia developed Piedmont region (2024) Discharge measurements, air temperature, water temperature, and gage height data for select streams in Maryland-Washington, DC-Virginia developed Piedmont region (2024)
As part of a larger study examining stream conditions and the effect of Best Management Practices in the Chesapeake Bay watershed, thirty small streams in the developed Piedmont of Maryland, Washington, DC, and Virginia were instrumented and monitored for gage height (water level), water temperature, and air temperature using Onset HOBO sensors from March to September 2024. In addition...
Micronesian Starling (Aplonis opaca) nesting data on Guam, 2015-2018 Micronesian Starling (Aplonis opaca) nesting data on Guam, 2015-2018
We designed and implemented snake-resistant nestboxes and tested their efficacy as a conservation tool by comparing nest survival in nestboxes to natural nests for Aplonis opaca (Såli, Micronesian Starling) on Guam. During 2016-2018, we monitored 340 nest attempts by 40 A. opaca pairs nesting in nestboxes and 53 attempts by 32 pairs nesting in natural nests (outside of nestboxes), for a...
Paleomagnetic Data from Newberry Volcano, Oregon, collected from 1977-2018 Paleomagnetic Data from Newberry Volcano, Oregon, collected from 1977-2018
This dataset consists of 424 paleomagnetic sites from Newberry Volcano. 15 sites were analyzed at the natural remanent magnetization level, 256 sites were analyzed with blanket demagnetization, and 153 sites were analyzed with modern stepwise demagnetization protocols. 412 sites yield acceptable paleomagnetic data.
Waterfowl Tracking VHF and GPS Data Relative to Sacramento Delta Fog and Clean Air Act Waterfowl Tracking VHF and GPS Data Relative to Sacramento Delta Fog and Clean Air Act
Heavy fog was hypothesized to interfere with flight of waterfowl by obscuring visibility and cause waterfowl to fly more in search for habitat below, which in turn, is likely to increase bioenergetic (caloric) cost related to increased time flying. The data sets include variables used to analyze the relationship between fog characteristics (occurrence, density, and longevity) and flight...
Luminescence Data for Earthquake History of the Needles Fault, Arizona Luminescence Data for Earthquake History of the Needles Fault, Arizona
The following report summarizes the dating results from sedimentary deposits sampled by the USGS Geologic Harzards Team and analyzed at the USGS Luminescence Geochronology Laboratory. Within this report, we detail the methodology used by the USGS Luminescence Geochronology Laboratory to obtain ages including sample preparation methods, luminescence measurement, equivalent dose...
