The Columbia River Gorge is the Columbia River’s long-held yet evolving passage through the volcanic arc of the Cascade Range. The globally unique setting of a continental-scale river bisecting an active volcanic arc at the leading edge of a major plate boundary creates a remarkable setting where dynamic volcanic and...

2021, Journal of Volcanology and Geothermal Research (419) 1-14
Raikoke, a small, unmonitored volcano in the Kuril Islands, erupted in June 2019. We integrate data from satellites (including Sentinel-2, TROPOMI, MODIS, Himawari-8), the International Monitoring System (IMS) infrasound network, and global lightning detection network (GLD360) with information from local authorities and social media to retrospectively characterize the eruptive sequence...
Methods for estimating regional skewness of annual peak flows in parts of eastern New York and Pennsylvania, based on data through water year 2013
Andrea G. Veilleux, Daniel M. Wagner
2021, Scientific Investigations Report 2021-5015
Bulletin 17C (B17C) recommends fitting the log-Pearson Type III (LP−III) distribution to a series of annual peak flows at a streamgage by using the method of moments. The third moment, the skewness coefficient (or skew), is important because the magnitudes of annual exceedance probability (AEP) flows estimated by using the...
The sensitivity of a unionid mussel (Lampsilis siliquoidea) to a permitted effluent and elevated potassium in the effluent
James L. Kunz, Ning Wang, David Martinez, Suzanne Dunn, Danielle M. Cleveland, Jeffery A. Steevens
2021, Environmental Toxicology and Chemistry (40) 3410-3420
Freshwater mussels are one of the most imperiled groups of animals in the world and are among the most sensitive species to a variety of chemicals. However, little is known about the sensitivity of freshwater mussels to wastewater effluents. The objectives of the present study were to (1) assess the...
Multidisciplinary constraints on magma compressibility, the pre-eruptive exsolved volatile fraction, and the H2O/CO2 molar ratio for the 2006 Augustine eruption, Alaska
Valerie K. Wasser, Taryn M. Lopez, Kyle R. Anderson, Pavel E. Izbekov, Jeffrey T. Freymueller
2021, Geochemistry, Geophysics, Geosystems (G-Cubed) (22) 1-24
Geodetically modeled reservoir volume changes during volcanic eruptions are commonly much smaller than the observed eruptive volumes. This discrepancy is thought to be partially due to the compressibility of magma, which is largely controlled by the presence of exsolved volatiles. The 2006 eruption of Augustine Volcano, Alaska, produced an eruptive...
Upper Grand Coulee: New views of a channeled scabland megafloods enigma
Richard B. Waitt, Brian F. Atwater, Karin Lehnigk, Isaac J. Larsen, Bruce N. Bjornstad, Michelle A. Hanson, Jim E. O'Connor
2021, Book chapter, From terranes to terrains: Geologic field guides on the construction and destruction of the Pacific Northwest
New findings about old puzzles occasion rethinking of the Grand Coulee, greatest of the scabland channels. Those puzzles begin with antecedents of current upper Grand Coulee. By a recent interpretation, the upper coulee exploited the former high-level valley of a preflood trunk stream that had drained to the southwest beside...

Song S. Qian, Jonathan G. Kennen, Jason May, Mary Freeman, Thomas F Cuffney
2021, Water Research (205)
A continuous-variable Bayesian network (cBN) model is used to link watershed development and climate change to stream ecosystem indicators. A graphical model, reflecting our understanding of the connections between climate change, weather condition, loss of natural land cover, stream flow characteristics, and stream ecosystem indicators is used as the basis for...

2021, Ichthyology & Herpetology 851-859
For species with variable phenology, it is often challenging to produce reliable estimates of population dynamics or changes in occupancy. The Arizona Toad (Anaxyrus microscaphus) is a southwestern USA endemic that has been petitioned for legal protection, but status assessments are limited by a lack of information...
Effects of variable-density thinning on non-native understory plants in coniferous forests of the Pacific Northwest
Yianna Bekris, Janet S. Prevey, Leslie C. Brodie, Connie Harrington
2021, Forest Ecology and Management (502)
Old-growth forests serve as critical habitat for many sensitive species, but management practices have diminished their prevalence, and former regions of old-growth are now dominated by second-growth stands lacking the structural heterogeneity, diversity, and species richness that these older forests possess. In...
Hypogenic karst of the Great Basin
Louise D. Hose, Harvey R. DuChene, Daniel Jones, Gretchen M. Baker, Zoe Havlena, Donald S. Sweetkind, Doug Powell
2021, Book chapter, Field Excursions from the 2021 GSA Section Meetings
Discoveries in the 1980s greatly expanded speleologists’ understanding of the role that hypogenic groundwater flow can play in developing caves at depth. Ascending groundwater charged with carbon dioxide and, especially, hydrogen sulfide can readily dissolve carbonate bedrock just below and above the water table. Sulfuric acid speleogenesis, in which anoxic,...

2021, Marine Biology (168)
Populations of the green turtle (Chelonia mydas), a mega-herbivore that consumes seagrasses, are recovering worldwide. Understanding green turtle adaptations to herbivory and responses to changes in seagrass availability will be critical to interpreting plant–herbivore interactions as green turtle populations continue to rebound. Ingesta particle size and...

Long-term epilimnetic temperature trends in Lake Mendota and Trout Lake, Wisconsin
Richard C Lathrop, Dale M. Robertson
2021, Report
Warming of lake surface waters has become a concern to limnologists and water managers because air temperatures, which directly affect near-surface water temperatures, are projected to increase in Wisconsin (WICCI 2011) as well as globally (IPCC 2018). This projected increase is in addition to the changes in air temperatures that...
