Atsuko Namiki, Yoshinori Ueno, Shaul Hurwitz, Michael Manga, Carolina Munoz-Saez, Fred Murphy
2016, Geochemistry, Geophysics, Geosystems (17) 3691-3716
In order to better understand the diverse discharge styles and eruption intervals observed at geothermal features, we performed three series of laboratory experiments with differing plumbing geometries. A single, straight conduit that connects a hot water bath (flask) to a vent (funnel) can originate geyser-like periodic eruptions, continuous discharge like...
Use of repeat surveys and flow and sediment transport modeling to support fish spawning reef placement in the Detroit River, MI
Paul J. Kinzel, Jonathan M. Nelson, Gregory W. Kennedy, David Bennion
2016, Conference Paper, Proceedings of River Flow 2016
The introduction of rock-rubble substrate in rivers, to enhance fish spawning habitat, represents a significant investment in planning, permitting and construction. Where river processes deposit sediment and cover the substrate, its value as fish spawning habitat can be diminished. Therefore, it is crucial in the site se-lection process, that substrate...

Marine species with planktonic larvae often have high spatial and temporal variation in recruitment that leads to subsequent variation in the ecology of benthic adults. Using a combination of published and unpublished data, we compared the population structure of the salt marsh snail, Littoraria irrorata, between the South Atlantic Bight...

Jacob Hutchinson, Erich H. Peitzsch, Adam Clark
2016, Conference Paper, Proceedings of the International Snow Science Workshop
The Going-to-the-Sun Road (GTSR) is the premier tourist attraction in Glacier National Park, Montana. The GTSR also traverses through and under 40 avalanche paths which pose a hazard to National Park Service (NPS) road crews during the annual spring snow plowing operation. Through a joint collaboration between the NPS and the U.S. Geological...

Erich H. Peitzsch, Jordy Hendrikx, Daniel B. Fagre
2016, Conference Paper, Proceedings of the International Snow Science Workshop
Structure from Motion (SfM), a photogrammetric technique, has been used extensively and successfully in many fields including geosciences over the past few years to create 3D models and high resolution digital elevation models (DEMs) from aerial or oblique photographs. SfM has recently been used in a limited capacity in snow avalanche research and...

Hurricane Sandy made landfall on October 29, 2012, near Brigantine, New Jersey, and had a transformative impact on Staten Island and the New York Metropolitan area. Of the 43 New York City fatalities, 23 occurred on Staten Island. The borough, with a population of approximately 500,000, experienced some of the...
Climate-induced warming of lakes can be either amplified or suppressed by trends in water clarity
Kevin C. Rose, Luke A. Winslow, Jordan S. Read, Gretchen J. A. Hansen
2016, Limnology and Oceanography Letters (1) 44-53
Climate change is rapidly warming aquatic ecosystems including lakes and reservoirs. However, variability in lake characteristics can modulate how lakes respond to climate. Water clarity is especially important both because it influences the depth range over which heat is absorbed, and because it is changing in many lakes. Here, we...

L.J. Patrick Muffler
2016, Article
Donald E. White was a leading scientist for the U.S. Geological Survey, where his career was devoted almost entirely to the study of hydrothermal processes in the Earth’s crust, from the dual perspectives of active geothermal systems and of extinct hydrothermal systems now represented only by ore deposits and alteration...

Movement reveals scale dependence in habitat selection of a large ungulate
Joseph Northrup, Charles R. Anderson Jr., Mevin Hooten, George Wittemyer
2016, Ecological Applications (26) 2746-2757
Ecological processes operate across temporal and spatial scales. Anthropogenic disturbances impact these processes, but examinations of scale dependence in impacts are infrequent. Such examinations can provide important insight to wildlife–human interactions and guide management efforts to reduce impacts. We assessed spatiotemporal scale dependence in habitat selection of mule deer (Odocoileus...
Statistically extracted fundamental watershed variables for estimating the loads of total nitrogen in small streams
Scott C. Kronholm, Paul D. Capel, Silvia Terziotti
2016, Environmental Modeling & Assessment (21) 681-690
Accurate estimation of total nitrogen loads is essential for evaluating conditions in the aquatic environment. Extrapolation of estimates beyond measured streams will greatly expand our understanding of total nitrogen loading to streams. Recursive partitioning and random forest regression were used to assess 85 geospatial, environmental, and watershed variables across 636...
Managing adaptively for multifunctionality in agricultural systems
Jennifer Hodbod, Olivier Barreteau, Craig R. Allen, Daniele Magda
2016, Journal of Environmental Management (183) 379-388
The critical importance of agricultural systems for food security and as a dominant global landcover requires management that considers the full dimensions of system functions at appropriate scales, i.e. multifunctionality. We propose that adaptive management is the most suitable management approach for such goals, given its ability to reduce uncertainty...

Driss Takir, Vishnu Reddy, Juan A. Sanchez, Michael K. Shepard, Joshua P. Emery
2016, Astronomical Journal (153)
In order to search for evidence of hydration on M-type asteroid (16) Psyche, we observed this object in the 3 μm spectral region using the long-wavelength cross-dispersed (LXD: 1.9–4.2 μm) mode of the SpeX spectrograph/imager at the NASA Infrared Telescope Facility. Our observations show that Psyche exhibits a 3 μm absorption feature, attributed...
