Sediment transport and deposition on a river-dominated tidal flat: An idealized model study
Christopher R. Sherwood, Shih-Nan Chen, W. Rockwell Geyer, David K. Ralston
2010, Journal of Geophysical Research C: Oceans (115)
A 3-D hydrodynamic model is used to investigate how different size classes of river-derived sediment are transported, exported and trapped on an idealized, river-dominated tidal flat. The model is composed of a river channel flanked by sloping tidal flats, a configuration motivated by the intertidal region of the Skagit River...

Carol Becker, S. Jerrod Smith, James R. Greer, Kevin A. Smith
2010, Scientific Investigations Report 2010-5047
The U.S. Geological Survey well profiler was used to describe arsenic-related water quality with well depth and identify zones yielding water with high arsenic concentrations in two production wells in central and western Oklahoma that yield water from the Permian-aged Garber-Wellington and Rush Springs aquifers, respectively. In addition, well-head samples...
Impacts and predictions of coastal change during hurricanes
Hilary Stockdon, Abby Sallenger
2010, Fact Sheet 2010-3012
Beaches serve as a natural barrier between the ocean and inland communities, ecosystems, and resources. These dynamic environments move and change in response to winds, waves, and currents. During a powerful hurricane, changes to beaches can be large, and the results are sometimes catastrophic. Lives are lost, communities are destroyed,...

Testing statistical self-similarity in the topology of river networks
Brent M. Troutman, Ricardo Mantilla, Vijay K. Gupta
2010, Journal of Geophysical Research F: Earth Surface (115)
Recent work has demonstrated that the topological properties of real river networks deviate significantly from predictions of Shreve's random model. At the same time the property of mean self-similarity postulated by Tokunaga's model is well supported by data. Recently, a new class of network model called random self-similar networks (RSN)...
A minimally invasive method for extraction of sturgeon oocytes
James S. Candrl, Diana M. Papoulias, Donald E. Tillitt
2010, North American Journal of Aquaculture (72) 184-187
Fishery biologists, hatchery personnel, and caviar fishers routinely extract oocytes from sturgeon (Acipenseridae) to determine the stage of maturation by checking egg quality. Typically, oocytes are removed either by inserting a catheter into the oviduct or by making an incision in the body cavity. Both methods can be time-consuming and...

Thomas J. Kwak, Mary Freeman
2010, Book chapter, Inland fisheries management in North America
Assessing and understanding the impacts of human activities on aquatic ecosystems has long been a focus of ecologists, water resources managers, and fisheries scientists. While traditional fisheries management focused on single-species approaches to enhance fish stocks, there is a growing emphasis on management approaches at community and ecosystem levels. Of...
Generalizing a nonlinear geophysical flood theory to medium-sized river networks
Vijay K. Gupta, Ricardo Mantilla, Brent M. Troutman, David Dawdy, Witold F. Krajewski
2010, Geophysical Research Letters (37)
The central hypothesis of a nonlinear geophysical flood theory postulates that, given space-time rainfall intensity for a rainfall-runoff event, solutions of coupled mass and momentum conservation differential equations governing runoff generation and transport in a self-similar river network produce spatial scaling, or a power law, relation between peak discharge and...
Temporal variations in Global Seismic Stations ambient noise power levels
A. T. Ringler, L.S. Gee, C. R. Hutt, D.E. McNamara
2010, Seismological Research Letters (81) 605-613
Recent concerns about time-dependent response changes in broadband seismometers have motivated the need for methods to monitor sensor health at Global Seismographic Network (GSN) stations. We present two new methods for monitoring temporal changes in data quality and instrument response transfer functions that are independent of...

Si-Fa Li, Qin-Ling Yang, Jia-Wei Xu, Cheng-Hui Wang, Duane Chapman, Guoping Lu
2010, Transactions of the American Fisheries Society (139) 937-946
The bighead carp Hypophthalmichthys nobilis is native to China but has been introduced to over 70 countries and is established in many large river systems. Genetic diversity and variation in introduced bighead carp have not previously been evaluated, and a systematic comparison among fish from different river systems was unavailable. In this...

Intra- and interspecific facilitation in mangroves may increase resilience to climate change threats
Mark Huxham, Marappullige P. Kumara, Loku P. Jayatissa, Ken W. Krauss, James Kairo, Joseph Langat, Maurizio Mencuccini, Martin W. Skov, Bernard Kirui
2010, Philosophical Transactions of the Royal Society B: Biological Sciences (365) 2127-2135
Mangroves are intertidal ecosystems that are particularly vulnerable to climate change. At the low tidal limits of their range, they face swamping by rising sea levels; at the high tidal limits, they face increasing stress from desiccation and high salinity. Facilitation theory may help guide mangrove management and restoration in...
