Schistosomiasis, or “snail fever”, is a parasitic disease affecting over 200 million people worldwide. People become infected when exposed to water containing particular species of freshwater snails. Habitats for such snails can be mapped using lightweight, inexpensive and field-deployable consumer-grade Unmanned Aerial Vehicles (UAVs), also known as drones. Drones can...
Variation in species composition, size and fitness of two multi-species sea turtle assemblages using different neritic habitats
Margaret M. Lamont, Darren Johnson
Nathan Freeman Putman, editor(s)
2021, Frontiers in Marine Science (7) 1-11
The neritic environment is rich in resources and as such plays a crucial role as foraging habitat for multi-species marine assemblages, including sea turtles. However, this habitat also experiences a wide array of anthropogenic threats. To prioritize conservation funds, targeting areas that support multi-species assemblages is ideal. This is particularly...

Emily M. Bristol, Craig T. Connolly, Thomas Lorenson, Bruce M. Richmond, Anastasia G. Ilgen, Charles R. Choens, Diana L. Bull, Mikhail Z. Kanevskiy, Go Iwahana, Benjamin M. Jones, James W. McClelland
2021, Frontiers in Earth Science (8)
Accelerating erosion of the Alaska Beaufort Sea coast is increasing inputs of organic matter from land to the Arctic Ocean, and improved estimates of organic matter stocks in eroding coastal permafrost are needed to assess their mobilization rates under contemporary conditions. We collected three permafrost cores (4.5–7.5 m long)...
Radiometric constraints on the timing, tempo, and effects of large igneous province emplacement
Jennifer Kasbohm, Blair Schoene, Seth D. Burgess
2021, Book chapter, Large igneous provinces: A driver of global environmental and biotic changes
There is an apparent temporal correlation between large igneous province (LIP) emplacement and global environmental crises, including mass extinctions. Advances in the precision and accuracy of geochronology in the past decade have significantly improved estimates of the timing and duration of LIP emplacement, mass extinction events, and global climate perturbations,...
Using high sample rate lidar to measure debris-flow velocity and surface geometry
Francis K. Rengers, Thomas D Rapstine, Michael Olsen, Kate E. Allstadt, Richard M. Iverson, Ben Leshchinsky, Maciej Obryk, Joel B. Smith
2021, Environmental and Engineering Geoscience (27) 113-126
Debris flows evolve in both time and space in complex ways, commonly starting as coherent failures but then quickly developing structures such as roll waves and surges. These processes are readily observed but difficult to study or quantify because of the speed at which they...
Groundwater discharge impacts marine isotope budgets of Li, Mg, Ca, Sr, and Ba
Kimberly Mayfield, Anton Eisenhauer, Danielle P. Santiago Ramos, John A. Higgins, Tristan Horner, Maureen Auro, Tomas Magna, Nils Moosdorf, Matthew Charette, Meagan Gonneea Eagle, Carolyn Brady, Nemanja Komar, Bernhard Peucker-Ehrenbrink, Adina Paytan
2021, Nature Communications (12)
Groundwater-derived solute fluxes to the ocean have long been assumed static and subordinate to riverine fluxes, if not neglected entirely, in marine isotope budgets. Here we present concentration and isotope data for Li, Mg, Ca, Sr, and Ba in coastal groundwaters to constrain the importance of...
Creel surveys for social-ecological systems focused fisheries management
Chelsey L. Nieman, Carolyn Iwicki, Abigail Lynch, Greg G. Sass, Christopher T. Solomon, Ashley Trudeau, Brett van Poorten
2021, Reviews in Fisheries Science & Aquaculture (29) 739-752
Recreational fisheries are social-ecological systems (SES), and knowledge of human dimensions coupled with ecology are critically needed to understand their system dynamics. Creel surveys, which typically occur in-person and on-site, serve as an important tool for informing fisheries management. Recreational fisheries creel data have the potential...
Muted responses to chronic experimental nitrogen deposition on the Colorado Plateau
Michala Lee Phillips, Daniel E. Winkler, Robin H. Reibold, Brooke Bossert Osborne, Sasha C. Reed
2021, Oecologia (195) 513-524
Anthropogenic nitrogen (N) deposition is significantly altering both community structure and ecosystem processes in terrestrial ecosystems across the globe. However, our understanding of the consequences of N deposition in dryland systems remains relatively poor, despite evidence that drylands may be particularly vulnerable to increasing N inputs....

Kīlauea Volcano, on the Island of Hawaiʻi, is surrounded and permeated by active groundwater systems that interact dynamically with the volcanic system. A generalized conceptual model of Hawaiian hydrogeology includes high-level dike-impounded groundwater, very permeable perched and basal aquifers, and a transition (mixing) zone between freshwater and saltwater. Most high-level...

Matthew R. Patrick, Tim R. Orr, Don Swanson, Bruce F. Houghton, editor(s)
2021, Professional Paper 1867
The 2008–2018 lava lake at the summit of Kīlauea marked the longest sustained period of lava lake activity at the summit in decades and provided a new opportunity for observing and understanding lava lake behavior. The individual chapters of this Professional Paper volume cover the basic chronology of the eruption,...
Views of a century of activity at Kīlauea Caldera—A visual essay

Matthew R. Patrick, Tim R. Orr, Don Swanson, Bruce F. Houghton, editor(s)
2021, Professional Paper 1867-B
The 2018 eruption of Kīlauea Volcano marked the end of the first sustained period of volcanic activity at Halemaʻumaʻu Crater in 94 years. The views of the lava lake (informally named “Overlook,” nestled within Halemaʻumaʻu) lasted for a decade and seemed timeless. But as we were recently reminded, the summit...

2021, Professional Paper 1867-A
The first eruption at Kīlauea’s summit in 25 years began on March 19, 2008, and persisted for 10 years. The onset of the eruption marked the first explosive activity at the summit since 1924, forming the new “Overlook crater” (as the 2008 summit eruption crater has been informally named) within...

Leonid A. Neymark, Christopher S. Holm-Denoma, Anatoly Larin, Richard J. Moscati, Yulia Plotkina
2021, Mineralium Deposita (56) 1177-1194
U-Pb dating of cassiterite and zircon from the Yazov granite (Transbaikalia region, Eastern Siberia, Russia) and cassiterite from spatially associated tin mineralization in the Tuyukan ore district in the Tonod uplift was conducted using in situ laser ablation inductively coupled plasma mass spectrometry. These analyses allow comparison of isotopic systematics...
The river corridor’s evolving connectivity of lotic and lentic waters
Judson Harvey, Noah Schmadel
2021, Frontiers in Water (2)
River corridors supply a substantial proportion of the fresh water for societal and ecological needs. Individual functions of flowing (lotic) streams and rivers and ponded (lentic) waterbodies such as lakes and reservoirs are well-studied, but their collective functions are not as well understood. Here we bring together nationally consistent river...
Simulating water and heat transport with freezing and cryosuction in unsaturated soil: Comparing an empirical, semi-empirical and physically-based approach
Joris C Stuurop, Sjoerd E. A. T. M van der Zee, Clifford I. Voss, Helen K French
2021, Advances in Water Resources (149)
Freezing of unsaturated soil is an important process that influences runoff and infiltration in cold-climate regions. We used a simple numerical model to simulate water and heat transport with phase change in unsaturated soil via three different approaches: empirical, semi-empirical and physically based. We compared the performance and parameterization of...

2021, Microbiology Resource Announcements (10)
We sequenced the coding-complete genome of an avian orthoavulavirus serotype 16 (AOAV-16) isolate recovered from emperor goose (Anser canagicus) feces collected in Alaska. The detection of AOAV-16 in North America and genomic sequencing of the resultant isolate confirms that...
Modeling hydrologic processes associated with soil saturation and debris flow initiation during the September 2013 storm, Colorado Front Range
Sujana Timilsina, Jeffrey D. Niemann, Sara L. Rathburn, Francis K. Rengers, Peter A. Nelson
2021, Landslides (18) 1741-1759
Seven days of extreme rainfall during September 2013 produced more than 1100 debris flows in the Colorado Front Range, about 78% of which occurred on south-facing slopes (SFS). Previously published soil moisture (volumetric water content) observations suggest that SFS were wetter than north-facing slopes (NFS) during...
