The 3D Elevation Program—Supporting Maine’s economy
Dan Walters
2023, Fact Sheet 2023-3036
IntroductionInland flooding, sea-level rise, and pollution pose challenges for Maine’s infrastructure and natural resources. A highly detailed, three-dimensional (3D) model of the Earth’s surface is allowing the State of Maine to address these challenges in an increasingly comprehensive and timely manner. In addition, highly accurate elevation data facilitate land development,...
Reach-scale associations between introduced Brook Trout and juvenile and stream-resident Bull Trout in Idaho
Nicholas S. Voss, Brett J. Bowersox, Michael C. Quist
2023, Transactions of American Fisheries Society (152) 835-848
ObjectiveNative Bull Trout Salvelinus confluentus populations can be influenced by a variety of stressors operating at multiple spatial scales, making the relative importance of biotic versus abiotic controls difficult to discern at small scales where monitoring and management typically occur. Nonnative Brook Trout S. fontinalis were widely introduced throughout western North...
Probabilistic source classification of large tephra producing eruptions using supervised machine learning: An example from the Alaska-Aleutian arc
Jordan Edward Lubbers, Matthew W. Loewen, Kristi L. Wallace, Michelle L. Coombs, Jason A. Addison
2023, Geochemistry, Geophysics, Geosystems (24)
Alaska contains over 130 volcanoes and volcanic fields that have been active within the last 2 million years. Of these, roughly 90 have erupted during the Holocene, with many characterized by at least one large explosive eruption. These large tephra-producing eruptions (LTPEs) generate orders of magnitude more...

Increasing ocean wave energy observed in Earth’s seismic wavefield since the late 20th century
Richard C. Aster, Adam T. Ringler, Robert Anthony, Thomas A. Lee
2023, Nature Communications (14)
Ocean waves excite continuous globally observable seismic signals. We use data from 52 globally distributed seismographs to analyze the vertical component primary microseism wavefield at 14–20 s period between the late 1980s and August 2022. This signal is principally composed of Rayleigh waves generated by ocean wave seafloor tractions at...
Importance of understanding bottom-up control when characterizing geothermal systems
Jared R. Peacock, Paul A. Bedrosian
2023, Conference Paper, Using the Earth to save the Earth (GRC transactions)
Methods designed to identify favorable areas for geothermal resources have traditionally been focused on near-surface information, namely data that can be compiled into a 2D map. However, these methods fail to account for the third dimension: depth. As a result, they do not incorporate deep crustal and mantle features like...

Laurence A. Clarfeld, Alexej P.K. Sirén, Brendan M. Mulhall, Tammy L. Wilson, Elena Bernier, John Farrell, Gus Lunde, Nicole Hardy, Katherine D. Gieder, Robert Abrams, Sue Staats, Scott McLellan, Therese M. Donovan
2023, Ecological Informatics (77)
Remote cameras (“trail cameras”) are a popular tool for non-invasive, continuous wildlife monitoring, and as they become more prevalent in wildlife research, machine learning (ML) is increasingly used to automate or accelerate the labor-intensive process of labelling (i.e., tagging) photos. Human-machine hybrid tagging approaches have been shown to greatly increase...

Dating the penultimate great earthquake in south-central Alaska using tree-ring crossdating and radiocarbon wiggle-matching
David J Barclay, Peter J. Haeussler, Robert C. Witter
2023, Quaternary Science Advances (13)
A forest bed of tree stumps currently in the intertidal zone at Girdwood, south-central Alaska, records coseismic submergence during the penultimate great earthquake. Tree-ring samples from ten spruce stumps were crossdated to develop a 149-year-long ring-width chronology. Radiocarbon wiggle-matching found that single-ring ages from the chronology were offset 28 ± 7 years older...
