Monica Palaseanu-Lovejoy, Jeffrey J. Danielson, Cindy A. Thatcher, Amy C. Foxgrover, Patrick L. Barnard, John Brock, Adam Young
2016, Journal of Coastal Research 162-173
Seacliff erosion is a serious hazard with implications for coastal management and is often estimated using successive hand-digitized cliff tops or bases (toe) to assess cliff retreat. Even if efforts are made to standardize manual digitizing and eliminate subjectivity, the delineation of cliffs is time-consuming and depends on the analyst's...
Water-level altitudes 2016 and water-level changes in the Chicot, Evangeline, and Jasper aquifers and compaction 1973–2015 in the Chicot and Evangeline aquifers, Houston-Galveston region, Texas
Mark C. Kasmarek, Jason K. Ramage, Michaela R. Johnson
2016, Scientific Investigations Map 3365
Most of the land-surface subsidence in the Houston-Galveston region, Texas, has occurred as a direct result of groundwater withdrawals for municipal supply, commercial and industrial use, and irrigation that depressured and dewatered the Chicot and Evangeline aquifers, thereby causing compaction of the aquifer sediments, mostly in the fine-grained silt and...

Calcareous microfossil-based orbital cyclostratigraphy in the Arctic Ocean
Rachel Marzen, Lauren H. DeNinno, Thomas M. Cronin
2016, Quaternary Science Reviews (149) 109-121
Microfaunal and geochemical proxies from marine sediment records from central Arctic Ocean (CAO) submarine ridges suggest a close relationship over the last 550 thousand years (kyr) between orbital-scale climatic oscillations, sea-ice cover, marine biological productivity and other parameters. Multiple paleoclimate proxies record glacial to interglacial cycles. To understand the climate-cryosphere-productivity...
Fragmented patterns of flood change across the United States
Stacey A. Archfield, Robert M. Hirsch, A. Viglione, G. Blöschl
2016, Geophysical Research Letters (43) 10232-10239
Trends in the peak magnitude, frequency, duration, and volume of frequent floods (floods occurring at an average of two events per year relative to a base period) across the United States show large changes; however, few trends are found to be statistically significant. The multidimensional behavior of flood change across...

Stephen J. Kalkhoff, Laura E. Hubbard, Joseph P.Schubauer-Berigan
2016, Report
The use of oxbow wetlands has been identified as a potential strategy to reduce nutrient transport from agricultural drainage tiles to streams in Iowa. In 2013 and 2014, a study was conducted in north-central Iowa in a native oxbow in the Lyons Creek watershed and two restored oxbow wetlands in...

William J. Stephenson, Jackson K. Odum, Charles W. Wicks Jr., Thomas L. Pratt, Richard J. Blakely
2016, Bulletin of the Seismological Society of America (106) 1461-1469
In 2001, a rare swarm of small, shallow earthquakes beneath the city of Spokane, Washington, caused ground shaking as well as audible booms over a five‐month period. Subsequent Interferometric Synthetic Aperture Radar (InSAR) data analysis revealed an area of surface uplift in the vicinity of the earthquake swarm. To investigate...

The east-central Great Basin near the Utah-Nevada border contains two great groundwater flow systems. The first, the White River regional groundwater flow system, consists of a string of hydraulically connected hydrographic basins in Nevada spanning about 270 miles from north to south. The northernmost basin is Long Valley...
Bacterial community diversity of the deep-sea octocoral Paramuricea placomus
Christina A. Kellogg, Steve W. Ross, Sandra D. Brooke
2016, PeerJ (4)
Compared to tropical corals, much less is known about deep-sea coral biology and ecology. Although the microbial communities of some deep-sea corals have been described, this is the first study to characterize the bacterial community associated with the deep-sea octocoral, Paramuricea placomus. Samples from five colonies of P. placomus were...

Demographic mechanisms underpinning genetic assimilation of remnant groups of a large carnivore
Nathaniel Mikle, Tabitha A. Graves, Ryan P. Kovach, Katherine C. Kendall, Amy C. Macleod
2016, Proceedings of the Royal Society B: Biological Sciences (283)
Current range expansions of large terrestrial carnivores are occurring following human-induced range contraction. Contractions are often incomplete, leaving small remnant groups in refugia throughout the former range. Little is known about the underlying ecological and evolutionary processes that influence how remnant groups are affected during range expansion. We used data...
