Late Holocene flood probabilities in the Black Hills, South Dakota with emphasis on the Medieval Climate Anomaly
Tessa M. Harden, James E. O'Connor, Daniel G. Driscoll
2015, Catena (130) 62-68
A stratigraphic record of 35 large paleofloods and four large historical floods during the last 2000 years for four basins in the Black Hills of South Dakota reveals three long-term flooding episodes, identified using probability distributions, at A.D.: 120–395, 900–1290, and 1410 to present. During the Medieval Climate Anomaly (~ A.D. 900–1300)...

Identifying multiple timescale rainfall controls on Mojave Desert ecohydrology using an integrated data and modeling approach for Larrea tridentata
Gene-Hua Crystal Ng, David R. Bedford, David M. Miller
2015, Water Resources Research (51)-3884
The perennial shrub Larrea tridentata is widely successful in North American warm deserts but is also susceptible to climatic perturbations. Understanding its response to rainfall variability requires consideration of multiple timescales. We examine intra-annual to multi-year relationships using model simulations of soil moisture and vegetation growth over 50 years in...
Using biotic ligand models to predict metal toxicity in mineralized systems
Kathleen S. Smith, Laurie S. Balistrieri, Andrew S. Todd
2015, Applied Geochemistry (57) 55-72
The biotic ligand model (BLM) is a numerical approach that couples chemical speciation calculations with toxicological information to predict the toxicity of aquatic metals. This approach was proposed as an alternative to expensive toxicological testing, and the U.S. Environmental Protection Agency incorporated the BLM into the 2007 revised aquatic life...
1000 dams down and counting
James E. O'Connor, Jeff J. Duda, Gordon E. Grant
2015, Science (348) 496-497
Forty years ago, the demolition of large dams was mostly fiction, notably plotted in Edward Abbey's novel The Monkey Wrench Gang. Its 1975 publication roughly coincided with the end of large-dam construction in the United States. Since then, dams have been taken down in increasing numbers as they have filled...

Sampling strategies are diverse and can be customized...
Mesozoic magmatism and timing of epigenetic Pb-Zn-Ag mineralization in the western Fortymile mining district, east-central Alaska: Zircon U-Pb geochronology, whole-rock geochemistry, and Pb isotopes
Cynthia Dusel-Bacon, J.N. Aleinkoff, W. C. Day, J.K. Mortensen
2015, Geosphere (11) 786-822
The Mesozoic magmatic history of the North American margin records the evolution from a more segmented assemblage of parautochthonous and allochthonous terranes to the more cohesive northern Cordilleran orogenic belt. We characterize the setting of magmatism, tectonism, and epigenetic mineralization in the western Fortymile mining district, east-central Alaska, where parautochthonous...
