Effect of wave skewness and asymmetry on the evolution of Fire Island, New York
Muhammed Parlak, Bilal Ayhan, John C. Warner, Tarandeep S. Kalra, Ilgar Safak
2022, Conference Paper
Bedload transport of sediment by waves and currents is one of the key physical processes that affect the evolution of coasts, nearshore areas, and the engineering practices there. Wave skewness and asymmetry, both of which increase as waves shoal, result in a net bedload sediment flux over a wave cycle....
Storm and tsunami overwash sediment transport inferred from recent deposits
Bruce E. Jaffe, SeanPaul La Selle
2022, Conference Paper, Proceedings of 37th conference on coastal engineering
Overwash deposits from storms and tsunamis record information about sediment transport and flow that can be used to inform hazard assessments. Here we explore deposits from two extreme wave events: (1) the 2012 Hurricane Sandy, a Category 5 hurricane that is the largest storm in the Atlantic basin on historical...
Evaluating the influence of the Forestry Reclamation Approach on throughfall quantity in eastern Kentucky
Morgan Gerlitz, Carmen T. Agouridis, Tanja N. Williamson, Chris D. Barton
2022, Reclamation Sciences (1) 13-24
The Appalachian Region is a rich forested ecosystem that has been impacted by coal mining. The Surface Mining Control and Reclamation Act of 1977 was enacted to resolve many of the environmental problems caused by surface mining. Reclamation practices resulted in excessive soil compaction and use of nonnative grasses and...
Salinification of coastal wetlands and freshwater management to support resilience
Beth Middleton, Jere Boudell
2022, Ecosystem Health and Sustainability (9)
Climates are rapidly changing in wetland ecosystems around the world and historical land-use change is not always given enough consideration in climate adaptation discussions. Historical changes to hydrology and other key environments can exacerbate vegetation stress; e.g., recent drought and flood episodes are likely more extreme because of climate change....
Density-dependent processes and population dynamics of native sculpin in a mountain river
Casey A. Pennock, Gary P. Thiede, Phaedra E. Budy
2022, Ecology of Freshwater Fish (32) 593-605
Understanding the processes governing population dynamics is important for effective conservation and environmental management. Disentangling the relative role of density-dependent versus density-independent processes on population dynamics is often made difficult by the inability to control for abiotic or biotic factors, but long-term datasets are...
Extending body condition scoring beyond measurable rump fat to estimate full range of nutritional condition for moose
Rebecca L. Levine, Rachel A. Smiley, Brett R. Jesmer, Brendan A. Oates, Jacob R. Goheen, Thomas R. Stephenson, Matthew Kauffman, Gary L. Fralick, Kevin L. Monteith
2022, Alces (58) 91-99
Moose (Alces alces) populations along the southern extent of their range are largely declining, and there is growing evidence that nutritional condition — which influences several vital rates – is a contributing factor. Moose body condition can presently be estimated only when there is measurable subcutaneous rump fat, which equates...

Sea otters in a California estuary: Detecting temporal and spatial dynamics with volunteer monitoring
Ron Eby, Susan Rosso, John Copriviza, Robert Scoles, Yohn Gideon, Joseph Mancino, Karl A. Mayer, Julie L. Yee, Kerstin Wasson
2022, Ecosphere (13)
Volunteer monitoring can support conservation of imperiled wildlife, by providing higher resolution data in space and time than those available from professional scientists. However, concerns have been raised that data collected by amateurs are inaccurate or inconsistent and thus do not allow for robust detection of spatial or temporal trends....
Regional water table in the Antelope Valley and Fremont Valley groundwater basins, Southwestern Mojave Desert, California, March 2014
Meghan C. Dick, Nicholas F. Teague
2022, Scientific Investigations Map 3420
Water levels were measured during March 2014 in wells in the Antelope Valley and Fremont Valley groundwater basins, southwestern Mojave Desert, California, in cooperation with the Antelope Valley-East Kern Water District, Palmdale Water District, and Littlerock Creek Irrigation District. A regional water-table map was constructed. Historical water-level data from the...
VIMTS: Variational-based Imputation for Multi-modal Time Series
Xiaowei Jia, Jennifer H. Fair, Benjamin Letcher
2022, Conference Paper, IEEE International Conference on Big Data Proceedings
Multi-modal time series data in real applications often contain data of different dimensionalities, e.g., high-dimensional modality such as image data series, and low-dimensional univariate time series. Multi-modal time series data with missing high-dimensional modal values are ubiquitous in real-world classification and regression applications. To accurately...

Hydrogen isotope behavior during rhyolite glass hydration under hydrothermal conditions
Michael R. Hudak, Ilya N. Bindeman, James M. Watkins, Jacob B. Lowenstern
2022, Geochimica et Cosmochimica Acta (337) 33-48
The diffusion of molecular water (H2Om) from the environment into volcanic glass can hydrate the glass up to several wt% at low temperature over long timescales. During this process, the water imprints its hydrogen isotope composition (δDH2O) to the glass (δDgl) offset by a glass-H2O fractionation factor (ΔDgl-H2O = δDgl – δDH2O) which is approximately −33‰ at Earth...
Characterization of a small population of the orangeblack Hawaiian damselfly (Megalagrion xanthomelas) in anchialine pools at Kaloko-Honokōhau National Historical Park, Hawai‘i Island
Robert W. Peck, Sarah Nash
2022, Proceedings of the Hawaiian Entomological Society (54) 93-109
The endangered orangeblack Hawaiian damselfly (Megalagrion xanthomelas) is a lowland inhabitant of freshwater and brackish wetland environments. Formerly one of the most widely distributed native insects in Hawai‘i, it now appears restricted to small populations on the islands of O‘ahu, Moloka‘i, Maui, and Hawai‘i. On Hawai‘i island, anchialine pools provide...

R. Blaine McCleskey, D. Kirk Nordstrom, Shaul Hurwitz, Daniel R. Colman, David A. Roth, Madeline Oxner Johnson, Eric S. Boyd
2022, Journal of Volcanology and Geothermal Research (432)
The Yellowstone Plateau Volcanic Field (YPVF) contains >10,000 thermal features including hot springs, pools, geysers, mud pots, and fumaroles with diverse chemical compositions. Arsenic (As) concentrations in YPVF thermal waters typically range from 0.005 to 4 mg/L, but an As concentration of 17 mg/L has been reported. Arsenic data from thermal springs,...

Jacob Richard Krause, Eric C. Janney, Summer M. Burdick, Alta C. Harris, Brian S. Hayes
2022, North American Journal of Fisheries Management (42) 1414-1432
In the western United States, water allocation decisions often incorporate the needs of endangered fish. In the Klamath River basin, an understanding of temporal variation in annual survival rates of Shortnose Suckers Chasmistes brevirostris and Lost River Suckers Deltistes luxatus and their relation to environmental drivers is critical to water...

Ikuo Towhata, Gonghui Wang, Qiang Xu, Chris Massey, editor(s)
2022, Book chapter, Coseismic landslides: Phenomena, long-term effects and mitigation
The 2002 M 7.9 Denali earthquake in Alaska, USA, was the largest inland earthquake in North America in nearly 150 years. The earthquake involved oblique thrusting but mostly strike-slip motion, and faults ruptured the ground surface over 330 km. Fault rupture occurred in a rugged, mountainous, subarctic environment with extensive...
Modeling reservoir release using pseudo-prospective learning and physical simulations to predict water temperature

Arindam Banerjee, Zhi-Hua Zhou, Evangelos E. Papalexakis, Matteo Riondato, editor(s)
2022, Conference Paper, Proceedings of the 2022 SIAM International Conference on Data Mining (SDM)
This paper proposes a new data-driven method for predicting water temperature in stream networks with reservoirs. The water flows released from reservoirs greatly affect the water temperature of downstream river segments. However, the information of released water flow is often not available for many reservoirs, which makes it difficult for...
