Data

This data release contains an image and video catalog of the 2018 summit collapse and lower East Rift Zone eruption of Kīlauea volcano, on the Island of Hawaiʻi. An intrusion of magma into Kīlauea’s lower East Rift Zone resulted in a four-month-long eruption from May 3 to September 5, 2018 (Neal and others, 2018). The eruption produced lava flows that covered an area of 35.5 square...

This data release makes available the data used to test and refine a remote sensing approach for estimating river discharge via critical flow theory. In rivers where flow conditions are near critical and well-defined standing waves are present, discharge can be inferred from measurements of wavelength and channel width made on an image. The goals of the study were to: 1) evaluate the

Mauna Loa volcano, Island of Hawaiʻi, erupted from November 27 to December 10, 2022, sending lava flows across the summit caldera (Mokuʻāweoweo) and into the upper Southwest Rift Zone, before focusing in the Northeast Rift Zone at fissure 3, sending a lava flow down the north flank that threatened a major highway (Zoeller and others, 2024). During the eruption, U.S. Geological Survey...

Climate often drives ungulate population dynamics, and as climates change, some areas may become unsuitable for species persistence. Unraveling the relationships between climate and population dynamics, and projecting them across time, advances ecological understanding that informs and steers sustainable conservation for species. Using pronghorn (Antilocapra americana) as an ecological...

These data were compiled to model ecosystem metabolism in the Glen Canyon Dam tailwater (e.g., the Colorado River below Glen Canyon Dam). The primary objective of our study was to develop a new ecosystem metabolism model which we refer to as the variable flow two-station (VFTS) model. The VFTS modifies the classic two-station metabolism approach to account for unsteady flow, thus...

The data provided are same-day matchups between in-situ, sonde-based phycocyanin measurements collected across the contiguous United States (CONUS) and Sentinel-2 Level-2A MSI data from 2015 to 2024. The in-situ data are composed of EXO sonde-based phycocyanin measurements, with other optically active water quality constituents included where available. These data are designed for...

Beginning at about 2:15 am on May 27, 2016, a landslide from the headscarp of the May 25, 2014, West Salt Creek rock-avalanche deposit (White and others, 2015; Coe and others, 2016; Lewis and others, 2023; Coe and others, 2026) moved into a sag pond at the head of the deposit. At about 2:30 am, the landslide caused the sag pond, which already had an elevated water level due to runoff...

This data release contains acoustic Doppler current profiler (ADCP) configuration information, stage-area and index velocity rating tables, and associated metadata for 22 U.S. Geological Survey (USGS) flow monitoring stations in the Sacramento-San Joaquin Delta.

These data are a compilation of example index velocity ratings used at USGS streamgaging stations. Each directory contains seven comma-delimited files consisting of a read me, the hydrographer developed rating, a table of discharge measurements used to develop the velocity rating, a mixture model analysis, statistically recommended rating, and the variance covariance matrix for both the

The U.S. Geological Survey is developing national water-use models to support water resources management in the United States. Model benefits include a nationally consistent estimation approach, greater temporal and spatial resolution of estimates, efficient and automated updates of results, and capabilities to forecast water use into the future and assess model uncertainty. In this data...

These data represent annual presence/absence determinations for northern long-eared bats (Myotis septentrionalis) derived from acoustic, mist netting, and artificial roost surveys with associated temporal, climatic, disease exposure, and spatial covariates for the Central Appalachian Mountains, United States, 2003–2023.
