2025, Completion Report 2021HG7
In 2020 the U.S. Geological Survey (USGS), as part of the Upper Mississippi River Restoration (UMRR) Program, began a new project to characterize potential hydrogeomorphic change associated with hydrogeomorphic units (HGUs) and their catenae (units linked by their association with sediment sources and flow origins). The goal of the project...
Fluid inclusion constraints on the geometry of the magmatic plumbing system beneath Mauna Loa – Part I: Lavas and tephras
Penny E. Wieser, Sarah C. Shi, Matthew Gleeson, Berenise Rangel, Charlotte DeVitre, Alexander T. Bearden, Kendra J. Lynn, Marie Camille-Caumon
2025, Bulletin of Volcanology (87)
There are few petrological constraints on magma storage depths at Mauna Loa, Hawai‘i. Yet understanding the geometry of the magmatic plumbing system is critical for interpreting geophysical signals of unrest at this very high-threat volcano. We address this gap by examining CO₂-rich fluid inclusions (FI) in lava and tephra from...

Michelle M. Irizarry-Ortiz, Sarah Yvette Murphy
2025, Journal of Hydrologic Engineering (30)
Gridded precipitation datasets are required for flood-typing historical annual peak streamflow events in basins across the Conterminous United States. Selected gridded precipitation datasets were validated over the period 1981–2013 through comparisons with gage data from the NOAA Global Historical Climatology Network daily (GHCNd). The ability of each gridded dataset to...

Chelsea P Scott, Nadine G. Reitman, Simone Bello
2025, Geophysical Research Letters (52)
The 1983 M6.9 Borah Peak, Idaho, earthquake is one of the largest historical normal fault earthquakes in the western United States. We quantified meter-scale vertical change along the 35 km-long rupture using topographic differencing of 1966 aerial imagery and 2019 lidar-derived data. The initial differencing results are largely obscured by horizontal...
