David C. Heimann, Patrick P. Rasmussen, Teri L. Cline, Lori M. Pigue, Holly R. Wagner
2010, Data Series 530
Suspended-sediment data from 18 selected surface-water monitoring stations in the lower Missouri River Basin downstream from Gavins Point Dam were used in the computation of annual suspended-sediment and suspended-sand loads for 1976 through 2008. Three methods of suspended-sediment load determination were utilized and these included the subdivision method, regression of...
Lessons from (triggered) tremor
Joan Gomberg
2010, Journal of Geophysical Research B: Solid Earth (115)
I test a “clock-advance” model that implies triggered tremor is ambient tremor that occurs at a sped-up rate as a result of loading from passing seismic waves. This proposed model predicts that triggering probability is proportional to the product of the ambient tremor rate and a function describing the efficacy...
Founding population size of an aquatic invasive species
Steven T. Kalinowski, Clint C. Muhlfeld, Christopher S. Guy, Benjamin Cox
2010, Conservation Genetics (11) 2049-2053
Non-native species of fish threaten native fishes throughout North America, and in the Rocky Mountains, introduced populations of lake trout threaten native populations of bull trout. Effective management of lake trout and other exotic species require understanding the dynamics of invasion in order to either suppress non-native populations or to...
Historical seismograms for unravelling a mysterious earthquake: The 1907 Sumatra Earthquake
Hiroo Kanamori, Luis Rivera, W.H.K. Lee
2010, Geophysical Journal International (183) 358-374
History of instrumental seismology is short. Seismograms are available only for a little more than 100 years; high-quality seismograms are available only for the last 50 years and the seismological database is very limited in time. To extend the database, seismograms of old events are of vital importance. Many unusual...
Improving and integrating data on invasive species collected by citizen scientists
2010, Biological Invasions (12) 3419-3428
Limited resources make it difficult to effectively document, monitor, and control invasive species across large areas, resulting in large gaps in our knowledge of current and future invasion patterns. We surveyed 128 citizen science program coordinators and interviewed 15 of them to evaluate their potential role in filling these gaps....

P. J. Bartlein, S. P. Harrison, Sandra Brewer, S. Connor, B.A.S. Davis, K. Gajewski, J. Guiot, T. I. Harrison-Prentice, A. Henderson, O. Peyron, I. C. Prentice, M. Scholze, H. Seppa, B. Shuman, S. Sugita, R.S. Thompson, A.E. Viau, J. Williams, H. Wu
2010, Climate Dynamics (37) 775-802
Subfossil pollen and plant macrofossil data derived from 14C-dated sediment profiles can provide quantitative information on glacial and interglacial climates. The data allow climate variables related to growing-season warmth, winter cold, and plant-available moisture to be reconstructed. Continental-scale reconstructions have been made for the mid-Holocene (MH, around 6 ka) and Last Glacial...
Using selective drainage methods to hydrologically-condition and hydrologically-enforce lidar-derived surface flow
Sandra K. Poppenga, Bruce Worstell, Jason M. Stoker, Susan Greenlee
2010, Conference Paper, Remote sensing and hydrology
The methods to extract surface flow from coarse elevation data are well documented; however, the methods to extract surface flow from high-resolution, high-vertical accuracy digital elevation models (DEMs) derived from light detection and ranging (lidar) are less documented, but yet more complex. As lidar data are increasingly used to generate...

Romeo M. Flores, Brianne D. Spear, Scott A. Kinney, Peter A. Purchase, Craig M. Gallagher
2010, Professional Paper 1777
The stratigraphy, correlation, mapping, and depositional history of coal-bearing strata in the Paleogene Fort Union and Wasatch Formations in the Powder River Basin were mainly based on measurement and description of outcrops during the early 20th century. Subsequently, the quality and quantity of data improved with (1) exploration and development...

Permeability profiles in granular aquifers using flowmeters in direct-push wells
D. Paradis, R. Lefebvre, R. H. Morin, E. Gloaguen
2010, Ground Water (49) 534-547
Numerical hydrogeological models should ideally be based on the spatial distribution of hydraulic conductivity (K), a property rarely defined on the basis of sufficient data due to the lack of efficient characterization methods. Electromagnetic borehole flowmeter measurements during pumping in uncased wells can effectively provide a continuous vertical distribution of K in...
