Christie Hegermiller, John C. Warner, Maitane Olabarrieta, Christopher R. Sherwood, Tarandeep S. Kalra
2022, JGR-Earth Surface (127)
Physical processes driving barrier island change during storms are important to understand to mitigate coastal hazards and to evaluate conceptual models for barrier evolution. Spatial variations in barrier island topography, landcover characteristics, and nearshore and back-barrier hydrodynamics can yield complex morphological change that requires models of increasing resolution and physical...
Influences of channel and floodplain modification on expansion of woody vegetation into Catahoula Lake, Louisiana, USA
R.F. Keim, L. Dugue, K.D. Latuso, S. Joshi, Sammy L. King, F.L. Willis
2022, Earth Surface Processes and Landforms (47) 1466-1479
Ecosystem structure of wetlands in managed floodplains depends on hydrological processes controlled by geomorphology and water management. Overlapping effects of direct modifications and geomorphic adjustments to management can combine to trigger changes to floodplain ecosystem structure. We examined the case of woody vegetation encroaching into the depressional Catahoula Lake, Louisiana,...

Cigdem Ozkan, Talea Mayo, Davina Passeri
Rafael Morales, editor(s)
2022, Journal of Marine Science and Engineering (10) 1-26
Wave energy conversion technologies have recently attracted more attention as part of global efforts to replace fossil fuels with renewable energy resources. While ocean waves can provide renewable energy, they can also be destructive to coastal areas that are often densely populated and vulnerable to coastal erosion. There have been...

2022, Journal of Applied Volcanology (11) 1-24
In November 2019, the fourth meeting on Volcano Observatory Best Practices workshop was held in Mexico City as a series of talks, discussions, and panels. Volcanologists from around the world offered suggestions for ways to optimize volcano-observatory crisis operations. By crisis, we mean unrest that may or may not lead...
Testing the potential of streamflow data to predict spring migration of an ungulate herds
Jason S. Alexander, Marissa L. Murr, Cheryl A. Eddy-Miller
Stefano Grignolio, editor(s)
2022, PLoS ONE (17) 1-18
In mountainous and high latitude regions, migratory animals exploit green waves of emerging vegetation coinciding with rising daily mean temperatures initiating snowmelt across the landscape. Snowmelt also causes rivers and streams draining these regions to swell, a process referred to as to as the ‘spring pulse.’ Networks of streamgages measuring...

In the United States, the Bald and Golden Eagle Protection Act prohibits take of golden eagles (Aquila chrysaetos) unless authorized by permit, and stipulates that all permitted take must be sustainable. Golden eagles are unintentionally killed in conjunction with many lawful activities (e.g., electrocution on power poles, collision with wind...
Enhanced bioremediation of RDX and co-contaminants perchlorate and nitrate using an anaerobic dehalogenating consortium in a fractured rock aquifer
Michelle Lorah, Eric Vogler, Fredrick E. Gebhardt, Duane Graves, Jennifer Grabowski
Y. Yeomin Yoon, editor(s)
2022, Chemosphere (294) 1-12
The potential neurotoxic and carcinogenic effects of the explosives compound RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) on human health requires groundwater remediation strategies to meet low cleanup goals. Bioremediation of RDX is feasible through biostimulation of native microbes with an organic carbon donor but may be less efficient, or not occur at all, in...
A landscape approach for identifying potential reestablishment sites for extirpated stream fishes: an example with Arctic grayling (Thymallus arcticus) in Michigan
Ralph William Tingley, Dana M. Infante, Emily M. Dean, Douglas W. Schemske, Arthur R. Cooper, Jared Ross, Wesley M. Daniel
2022, Hydrobiologia (849) 1397-1415
Habitat degradation combined with climate change increases the threat of extinction for stream fishes. In response to these threats, efforts to reestablish species within formerly occupied streams or translocation to suitable areas may be effective conservation strategies. In the absence of historic species presence data, identifying locations where suitable habitat...

Geomorphic responses of fluvial systems to climate change: A habitat perspective
Kyle E. Juracek, Faith A. Fitzpatrick
2022, River Research and Applications (38) 757-775
Fluvial systems provide a variety of habitats that support thousands of species including many that are threatened or endangered. Moreover, these habitats, which range from aquatic and riparian to floodplain, are important for the variety of ecosystem services they provide. In addition to water temperature and streamflow change, geomorphic change...
Alaska Volcano Observatory archive of seismic drum records of eruptions of Augustine Volcano (1986), Redoubt Volcano (1989–90), Mount Spurr (1992), and Pavlof Volcano (1996), and the 1996 earthquake swarm at Akutan Peak
James P. Dixon, John A. Power
2022, Data Report 1146
The advent of continuous digital recording of seismograph stations in Alaska did not occur until the fall of 2002. Continuous records of seismic waveforms prior to 2002 were recorded only in analog form. The Alaska Volcano Observatory (AVO) has a substantial archive of continuous analog records made on helicorders in...

Dynamic Global Vegetation Models (DGVM) are powerful tools for studying complicated ecosystem processes and global changes. This review article synthesizes the developments and applications of the Integrated Biosphere Simulator (IBIS), a DGVM, over the past two decades. IBIS has been used to evaluate carbon, nitrogen, and water cycling in terrestrial...
A novel regression method for harmonic analysis of time series
Qiang Zhou, Zhe Zhu, George Z. Xian, Congcong Li
2022, ISPRS Journal of Photogrammetry and Remote Sensing (185) 48-61
Harmonic analysis of time series is an important technique in remote sensing to reveal seasonal land surface dynamics. However, frequency selection in the harmonic analysis is often difficult because high-frequency components are useful for delineating seasonal dynamics but sensitive to noise and gaps in time series. On the other hand,...

2022, Journal of Applied Ichthyology (38) 137-148
Over the past two decades, extensive monitoring has been conducted in the St. Clair – Detroit River System to describe spatial and temporal patterns of lake sturgeon (Acipenser fulvescens). To characterize spatial patterns in juvenile lake sturgeon (<1000 mm TL) based on survey collections, ‘hot spots’ were...
The accuracy and consistency of 3D Elevation Program data: A systematic analysis
Jason M. Stoker, Barry Miller
2022, Remote Sensing (14)
The 3D Elevation Program (3DEP) has created partnership opportunities to increase the collection of high-resolution elevation data across the United States, eventually leading to complete coverage of high-resolution, three-dimensional (3D) information from light detection and ranging (lidar) data across the entire country (interferometric synthetic aperture radar in Alaska). While 3DEP...
Phenomenological and mechanistic modeling of recreational angling behavior using creel data
Alexander J. Jensen, Steven J. Dundas, James Peterson
2022, Fisheries Research (249)
Improved understanding of angling behavior in recreational fisheries can help managers account for partial controllability in systems in which angling effort is not directly regulated. Relevant aspects of angling behavior include fishing participation, site choice, and catch-and-release actions and can be considered at scales of both aggregate fishing effort and...
