Glaciers are the largest reservoir of freshwater on Earth, supporting one third of the world's population. The Himalaya possess one of the largest resources of snow and ice, which act as a freshwater reservoir for more than 1.3 billion people. This article describes a new project called HIMALA, which focuses...
A model for Iapetan rifting of Laurentia based on Neoproterozoic dikes and related rocks
William C. Burton, Scott Southworth
2010, GSA Memoirs (206) 455-476
Geologic evidence of the Neoproterozoic rifting of Laurentia during breakup of Rodinia is recorded in basement massifs of the cratonic margin by dike swarms, volcanic and plutonic rocks, and rift-related clastic sedimentary sequences. The spatial and temporal distribution of these geologic features varies both within and between the massifs but...
Viscoelastic-cycle model of interseismic deformation in the northwestern United States
F. F. Pollitz, Patricia McCrory, Doug Wilson, Jerry Svarc, Christine Puskas, Robert B. Smith
2010, Geophysical Journal International (181) 665-696
We apply a viscoelastic cycle model to a compilation of GPS velocity fields in order to address the kinematics of deformation in the northwestern United States. A viscoelastic cycle model accounts for time-dependent deformation following large crustal earthquakes and is an alternative to block models for explaining the interseismic crustal...
Understanding behavioral responses of fish to pheromones in natural freshwater environments
Nicholas S. Johnson, Weiming Li
2010, Journal of Comparative Physiology A (196) 701-711
There is an abundance of experimental studies and reviews that describe odorant-mediated behaviors of fish in laboratory microcosms, but research in natural field conditions has received considerably less attention. Fish pheromone studies in laboratory settings can be highly productive and allow for controlled experimental designs; however, laboratory tanks and flumes...

Analytical models for the groundwater tidal prism and associated benthic water flux
Jeffrey N. King, Ashish J. Mehta, Robert G. Dean
2010, Hydrogeology Journal (18) 203-215

New software methods in radar ornithology using WSR-88D weather data and potential application to monitoring effects of climate change on bird migration
Reginald Mead, John Paxton, Richard S. Sojda

2010, Conference Paper, 2010 International Congress on Environmental Modelling and Software; Modelling for Environment's Sake, Fifth Biennial Meeting, Ottawa, Canada
Radar ornithology has provided tools for studying the movement of birds, especially related to migration. Researchers have presented qualitative evidence suggesting that birds, or at least migration events, can be identified using large broad scale radars such as the WSR-88D used in the NEXRAD weather surveillance system. This is potentially...

Model-based evaluation of highly and low pathogenic avian influenza dynamics in wild birds
Viviane Hénaux, Michael D. Samuel, Christine M. Bunck
2010, PLoS ONE (5)
There is growing interest in avian influenza (AI) epidemiology to predict disease risk in wild and domestic birds, and prevent transmission to humans. However, understanding the epidemic dynamics of highly pathogenic (HPAI) viruses remains challenging because they have rarely been detected in wild birds. We used modeling to integrate available...

W. Andrew Jackson, J.K. Bohlke, Baohua Gu, Paul B. Hatzinger, Neil C. Sturchio
2010, Environmental Science & Technology (44) 4869-4876
Perchlorate (ClO4−) has been detected widely in groundwater and soils of the southwestern United States. Much of this ClO4− appears to be natural, and it may have accumulated largely through wet and dry atmospheric deposition. This study evaluates the isotopic composition of natural ClO4− indigenous to the southwestern U.S. Stable...
