2023, River Research and Applications (39) 1457-1468
Accurate knowledge of the speed at which water moves along a river is essential for understanding ecohydraulic processes and managing natural resources. Measuring flow velocity via remote sensing can be more efficient than conventional field methods, and powerful computational techniques for inferring velocity fields from...
Seasonal shifts in diel vertical migrations by lake-dwelling coastal cutthroat trout, Oncorhynchus clarkii clarkii, reflect thermal regimes and prey distributions
Zachary R. Thomas, David Beauchamp, Casey P. Clark, Thomas P. Quinn
2023, Ecology of Freshwater Fish (32) 842-851
Lakes provide important habitat for salmonids that may use them as a primary feeding area between periods of reproduction. The seasonal changes in vertical thermal structure in lakes can affect the distribution of salmonids on seasonal and diel time scales as they search for,...
Volcanic earthquake catalog enhancement using integrated detection, matched-filtering, and relocation tools
Darren Tan, David Fee, Alicia J. Hotovec-Ellis, J. Pesicek, Matthew M. Haney, John Power, T. Girona
2023, Frontiers in Earth Science (11)
Volcanic earthquake catalogs are an essential data product used to interpret subsurface volcanic activity and forecast eruptions. Advances in detection techniques (e.g., matched-filtering, machine learning) and relative relocation tools have improved catalog completeness and refined event locations. However, most volcano observatories have yet to incorporate these techniques into...

Marketa Zimova, Brian Weeks, David E. Willard, Sean T Giery, Vitek Jirinec, Ryan C. Burner, Benjamin M Winger
2023, Proceedings of the National Academy of Sciences (PNAS) (120)
Across the globe, bird morphology is changing rapidly. Although trajectories of change are frequently consistent across studies, rates of change among species vary in magnitude—a phenomenon that remains unexplained. By analyzing two independently collected datasets demonstrating consistent changes in morphology in 129 species, we show that rates of phenotypic change...
The weight of New York City: Possible contributions to subsidence from anthropogenic sources
Thomas E. Parsons, Pei-Chin Wu, Meng (Matt) Wei, Steven D’Hondt
2023, Earth's Future (11)
New York City faces accelerating inundation risk from sea level rise, subsidence, and increasing storm intensity from natural and anthropogenic causes. Here we calculate a previously unquantified contribution to subsidence from the cumulative mass and downward pressure exerted by the built environment of the city. We enforce...
Spawning locations of pallid sturgeon in the Missouri River corroborate the mechanism for recruitment failure
Tanner L. Cox, Christopher S. Guy, Luke M. Holmquist, Molly A. H . Webb
2023, Fishes (8)
Conservation propagation of pallid sturgeon (Scaphirhynchus albus) upstream of Fort Peck Reservoir, Montana, USA has successfully recruited a new generation of spawning-capable pallid sturgeon where there would otherwise be fewer than 30 remaining wild reproductively mature pallid sturgeon. Successful recovery of pallid sturgeon will now rely on the behavior of...

Dawnika Blatter, Thomas W. Sisson, W. Ben Hankins
2023, Contributions to Mineralogy and Petrology (178)
Garnet’s stability in arc magmas and its influences on their differentiation were explored experimentally in a typical basalt, andesite, and dacite at conditions of 0.9–1.67 GPa, 800–1300 °C, with 2–9 wt.% added H2O, and with oxygen fugacity buffered near Re + O2 = ReO2 (~ Ni-NiO + 1.7 log10 bars). Garnet did not grow at 0.9 GPa in any of...

2023, Precambrian Research (391)
The Paleoproterozoic Nagssugtoqidian Orogen is one of the principal tectonic features related to the assembly of Nuna, extending across Greenland from east to west and forming an orogenic belt separating the North Atlantic Craton on the south from the Rae Craton on the north. In South-East Greenland,...
Precipitation, submarine groundwater discharge of nitrogen, and red tides along the southwest Florida Gulf coast
Bruce E. Kurtz, James E. Landmeyer, James K. Culter
2023, Heliyon (9)
Blooms of the dinoflagellate Karenia brevis occur almost every year along the southwest Florida Gulf coast. Long-duration blooms with especially high concentrations of K. brevis, known as red tides, destroy marine life through production of neurotoxins. Current hypotheses are that red tides originate...

Weak degassing from remote Alaska volcanoes characterized with a new airborne Imaging DOAS instrument and a suite of in situ sensors
Christoph Kern, Peter J. Kelly
2023, Frontiers in Earth Science (11)
Gas emissions from volcanoes occur when volatile species exsolve from magmatic and hydrothermal systems and make their way to the surface. Measurements of emitted gases therefore provide insights into volcanic processes. On 16 July 2021, we made airborne measurements of weak gas plumes emitted from four remote Alaska volcanoes: Iliamna...

2023, Conservation Biology (37)
Biodiversity and human well-being strategies are only as good as the set of ideas that people think about. This article evaluates value-focused thinking (VFT), a framework that focuses on creating objectives and strategy ideas that are responsive to the objectives. We performed a proof-of-concept study of VFT on six planning...
Magnitude and frequency of floods on Kauaʻi, Oʻahu, Molokaʻi, Maui, and Hawaiʻi, State of Hawaiʻi, based on data through water year 2020
Jackson N. Mitchell, Daniel M. Wagner, Andrea G. Veilleux
2023, Scientific Investigations Report 2023-5014
Accurate estimates of flood magnitude and frequency are needed to (1) optimize the design and location of infrastructure, including dams, culverts, bridges, industrial buildings, and highways, and (2) inform flood-zoning and flood-insurance studies. The U.S. Geological Survey (USGS), in cooperation with the State of Hawaiʻi Department of Transportation, estimated flood...
Quantification of geodetic strain rate uncertainties and implications for seismic hazard estimates
Jeremy Maurer, Kathryn Zerbe Materna
2023, Geophysical Journal International (234) 2128-2142
Geodetic velocity data provide first-order constraints on crustal surface strain rates, which in turn are linked to seismic hazard. Estimating the 2-D surface strain tensor everywhere requires knowledge of the surface velocity field everywhere, while geodetic data such as Global Navigation Satellite System (GNSS) only have spatially scattered measurements...

2023, Molecular Biology and Evolution (40)
Convergent adaptation to the same environment by multiple lineages frequently involves rapid evolutionary change at the same genes, implicating these genes as important for environmental adaptation. Such adaptive molecular changes may yield either change or loss of protein function; loss of function can eliminate newly deleterious proteins or reduce...
