The 35-year-long Puʻuʻōʻō eruption, on the East Rift Zone of Kīlauea Volcano, was the longest volcanic eruption on the Island of Hawaiʻi in the past 100 years (Wright and Klein 2014; Mulliken and others 2023). The eruption, whose vent area was focused at and around Puʻuʻōʻō cone, produced episodic fountaining in its initial few years followed by decades of effusive activity that created...

A reach of the Sacramento River near Glenn, California, was selected as a field site to test a sensor payload developed by the U.S. Geological Survey and the National Aeronautics and Space Administration for estimating surface flow velocities in rivers. The payload, called the River Observing System (RiOS), can be deployed from an uncrewed aircraft system (UAS). RiOS includes visible and...

This USGS data release contains datasets and metadata associated with identifying locations of groundwater seepage to streams in the Upper Shawsheen River Watershed in Massachusetts. Data were collected in August 2023 to characterize the spatial distribution of groundwater seeps along streambanks within Elm Brook, Hartwell Brook, and the Shawsheen River. Discharge measurements were made...

The 2018 eruption of Kīlauea Volcano included both a large effusive eruption on the lower East Rift Zone and associated collapse and subsidence of the caldera floor at the summit (Anderson and others 2019; Neal and others 2019; Patrick and others 2020). Lava erupted from 24 fissures on the lower East Rift Zone over four months, with high effusion rates (>100 m3 s-1) often supplying lava...

This dataset includes thin section images, automated mineralogy mineral maps, whole-rock geochemical data, and whole-rock Nd-Sr-Pb isotopic analysis of samples collected from nine mafic-ultramafic outcrops in the Wet Mountains, southern Colorado, during the summer of 2022. These data will accompany an upcoming journal publication and are intended to supplement recently collected airborne...

In 2022, the USGS, in cooperation with the U.S. Air Force Civil Engineer Center (USAF/CEC), performed geophysical surveys at two areas of interest within and near Ellsworth Air Force Base (EAFB) to delineate the Cretaceous Pierre Shale bedrock. Electrical resistivity tomography (ERT) data were collected in two grid patterns using the dipole-dipole array within and near EAFB and site...

This data release contains about 60 million point cloud data points collected during 27 scans of a section of the western shoreline of the Shinnecock Peninsula in Suffolk County, New York. Data were collected during July and October of 2022. Data are provided as .las files with points classified as either bare earth (GROUND_SN_BRIC_BL_2022_v03.0 (2).las), vegetation (VEGETATION_SN_BRIC...

As part of the periodic update of the geothermal energy assessments for the USA (e.g., last update by Williams and others, 2008), a new three-dimensional temperature map has been constructed for the Great Basin, USA. Williams and DeAngelo (2011) identified uncertainty in estimates of conductive heat flow near land surface as the largest contributor to uncertainty in previously published

These data were collected as part of a trapping effort for endangered threespine stickleback in Soledad Canyon, Santa Clara River watershed in California. The two-year survey effort took place in 2021 and 2022. We reported survey reach identities, stream sections, and numbers of fish captured per trapping effort.

Tiltmeter data from Kīlauea stations (ESC, IKI, JKA, KAE, POC, POO, SDH, SMC, UWE) from January 1 to December 31, 2021. These data were collected in 2021 by Andria P. Ellis of the USGS Hawaiian Volcano Observatory. The authors thank Sarah Conway for conducting many of clock resets for these tiltmeters in 2021.

Tiltmeter data from borehole tilt stations UWE and SDH from January 1 to December 31, 2020, spanning a Kīlauea summit intrusion and summit eruption that began on December 20, 2020. These data were collected in 2020 by Andria P Ellis and Ingrid A Johanson of the USGS Hawaiian Volcano Observatory. The authors thank Sarah Conway for conducting the nearly monthly clock resets for these...
