Time-lapse gravity data for monitoring and modeling artificial recharge through a thick unsaturated zone
Jeffrey R. Kennedy, Ty P.A. Ferre, Benjamin Creutzfeldt
2016, Water Resources Research (52) 7244-7261
Groundwater-level measurements in monitoring wells or piezometers are the most common, and often the only, hydrologic measurements made at artificial recharge facilities. Measurements of gravity change over time provide an additional source of information about changes in groundwater storage, infiltration, and for model calibration. We demonstrate that for an artificial...
Persistence and diversity of directional landscape connectivity improves biomass pulsing in expanding and contracting wetlands
Simeon Yurek, Donald L. DeAngelis, Joel C. Trexler, Stephen Klassen, Laurel G. Larsen
2016, Ecological Complexity (28) 1-11
In flood-pulsed ecosystems, hydrology and landscape structure mediate transfers of energy up the food chain by expanding and contracting in area, enabling spatial expansion and growth of fish populations during rising water levels, and subsequent concentration during the drying phase. Connectivity of flooded areas is dynamic as waters rise and...

Is consolidation drainage an indirect mechanism for increased abundance of cattail in northern prairie wetlands?
Mark T. Wiltermuth, Michael J. Anteau
2016, Wetlands Ecology and Management (24) 533-544
In the Prairie Pothole Region of North America, disturbances to wetlands that disrupt water-level fluctuations in response to wet–dry climatic conditions have the potential to alter natural vegetative communities in favor of species that proliferate in stable environments, such as cattail (Typha spp.). We evaluated the effect of water-level dynamics...

Aubrey R. Bunch
2016, Proceedings of the Indiana Academy of Science (125) 137-150
Transport of excess nutrients and total suspended solids (TSS) such as sediment by freshwater systems has led to degradation of aquatic ecosystems around the world. Nutrient and TSS loads from Midwestern states to the Mississippi River are a major contributor to the Gulf of Mexico Hypoxic Zone, an area of...

Dynamic reusable workflows for ocean science
Richard P. Signell, Filipe Fernandez, Kyle Wilcox
2016, Journal of Marine Science and Engineering (4)
Digital catalogs of ocean data have been available for decades, but advances in standardized services and software for catalog search and data access make it now possible to create catalog-driven workflows that automate — end-to-end — data search, analysis and visualization of data from multiple distributed sources. Further, these workflows...

2016, Proceedings of the National Academy of Sciences (113) E6551-E6552
Krauss et al. (1) use lack of detection of highly pathogenic (HP) H5 clade 2.3.4.4 (henceforth "H5") influenza A viruses (IAVs) from >22,000 wild bird samples collected in North America in 2014–2015 to argue that HP H5 IAVs disappeared from waterfowl and that unresolved mechanisms restrict emergence and perpetuation of...

Mark D. Kozar, Katherine S. Paybins
2016, Scientific Investigations Report 2016-5048
In January 2014, a storage tank leaked, spilling a large quantity of 4-methylcyclohexane methanol into the Elk River in West Virginia and contaminating the water supply for more than 300,000 people. In response, the West Virginia Legislature passed Senate Bill 373, which requires the West Virginia Department of Health and...
Changes in phosphorus concentrations and loads in the Assabet River, Massachusetts, October 2008 through April 2014
Jennifer G. Savoie, Leslie A. DeSimone, John R. Mullaney, Marc J. Zimmerman, Marcus C. Waldron
2016, Scientific Investigations Report 2016-5063
Treated effluent discharged from municipal wastewater-treatment plants to the Assabet River in central Massachusetts includes phosphorus, which leads to increased growth of nuisance aquatic plants that decrease the river’s water quality and aesthetics in impounded reaches during the growing season. To improve the river’s water quality and aesthetics, the U.S....

Shauna M. Baillie, Andrew M. Muir, Michael J. Hansen, Charles C. Krueger, Paul Bentzen
2016, BMC Evolutionary Biology (16) 1-16
BackgroundAdaptive radiation involving a colonizing phenotype that rapidly evolves into at least one other ecological variant, or ecotype, has been observed in a variety of freshwater fishes in post-glacial environments. However, few studies consider how phenotypic traits vary with regard to neutral genetic partitioning along...

Stephen J. Cauller, Lois M. Voronin, Mary M. Chepiga
2016, Scientific Investigations Report 2016-5035
Rapid population growth since the 1930s in Ocean County and vicinity, New Jersey, has placed increasing demands upon the area’s freshwater resources. To examine effects of groundwater withdrawals, a three-dimensional groundwater-flow model was developed to simulate the groundwater-flow systems of five area aquifers: the unconfined Kirkwood-Cohansey aquifer system and...

Selected techniques for monitoring water movement through unsaturated alluvium during managed aquifer recharge
Joseph M. Nawikas, David R. O’Leary, John A. Izbicki, Matthew K. Burgess
2016, Open-File Report 2016-1180
Managed aquifer recharge is used to augment natural recharge to aquifers. It can be used to replenish aquifers depleted by pumping or to store water during wetter years for withdrawal during drier years. Infiltration from ponds is a commonly used, inexpensive approach for managed aquifer recharge.At some managed...

Low-δD hydration rinds in Yellowstone perlites record rapid syneruptive hydration during glacial and interglacial conditions
Ilya N. Bindeman, Jacob B. Lowenstern
2016, Contributions to Mineralogy and Petrology (171) 1-24
Hydration of silicic volcanic glass forms perlite, a dusky, porous form of altered glass characterized by abundant “onion-skin” fractures. The timing and temperature of perlite formation are enigmatic and could plausibly occur during eruption, during post-eruptive cooling, or much later at ambient temperatures. To learn more about the origin of...
