Jeffrey J. Danielson, John Brock, Daniel M. Howard, Dean B. Gesch, Jamie M. Bonisteel-Cormier, Laurinda J. Travers
2013, Data Series 769
Topobathymetric Digital Elevation Models (DEMs) are a merged rendering of both topography (land elevation) and bathymetry (water depth) that provides a seamless elevation product useful for inundation mapping, as well as for other earth science applications, such as the development of sediment-transport, sea-level rise, and storm-surge models. This 1/9-arc-second (approximately...
Dissolved oxygen fluctuations in karst spring flow and implications for endemic species: Barton Springs, Edwards aquifer, Texas, USA
Barbara Mahler, Renan Bourgeais
2013, Journal of Hydrology (505) 291-298
Karst aquifers and springs provide the dissolved oxygen critical for survival of endemic stygophiles worldwide, but little is known about fluctuations of dissolved oxygen concentrations (DO) and factors that control those concentrations. We investigated temporal variation in DO at Barton Springs, Austin, Texas, USA. During 2006–2012, DO fluctuated by as...

Isabella Mariotto, Prasad S. Thenkabail, Alfredo Huete, E. Terrence Slonecker, Alexander Platonov
2013, Remote Sensing of Environment (139) 291-305
Precise monitoring of agricultural crop biomass and yield quantities is critical for crop production management and prediction. The goal of this study was to compare hyperspectral narrowband (HNB) versus multispectral broadband (MBB) reflectance data in studying irrigated cropland characteristics of five leading world crops (cotton, wheat, maize, rice, and alfalfa) with...
Odor-conditioned rheotaxis of the sea lamprey: Modeling, analysis and validation
Jongeun Choi, Soo Jean, Nicholas S. Johnson, Cory O. Brant, Weiming Li
2013, Bioinspiration and Biomimetics (8)
Mechanisms for orienting toward and locating an odor source are sought in both biology and engineering. Chemical ecology studies have demonstrated that adult female sea lamprey show rheotaxis in response to a male pheromone with dichotomous outcomes: sexually mature females locate the source of the pheromone whereas immature females swim...
Recent lake ice-out phenology within and among lake districts of Alaska, U.S.A.
Christopher D. Arp, Benjamin M. Jones, Guido Grosse
2013, Limnology and Oceanography (58) 2013-2028
The timing of ice-out in high latitudes is a fundamental threshold for lake ecosystems and an indicator of climate change. In lake-rich regions, the loss of ice cover also plays a key role in landscape and climatic processes. Thus, there is a need to understand lake ice phenology at multiple...

Plant invasions in protected areas of tropical pacific islands, with special reference to Hawaii
R. Flint Hughes, Jean-Yves Meyer, Lloyd L. Loope
2013, Book chapter, Plant Invasions in Protected Areas
Isolated tropical islands are notoriously vulnerable to plant invasions. Serious management for protection of native biodiversity in Hawaii began in the 1970s, arguably at Hawaii Volcanoes National Park. Concerted alien plant management began there in the 1980s and has in a sense become a model for protected areas throughout Hawaii...
Reconnaissance investigation of the rough diamond resource potential and production capacity of Côte d’Ivoire
Peter G. Chirico, Katherine C. Malpeli
2013, Scientific Investigations Report 2013-5185
Ethnic and political conflict developed into open civil war in Côte d’Ivoire in 2002, leading to a de facto partitioning of the country into the government-controlled south and the rebel-controlled north. Côte d’Ivoire’s two main diamond mining areas, Séguéla and Tortiya, are located in the north, under what was, until...

2013, Marine Geology (345) 294-303
Morphological trends of three distinct intertidal environments in South San Francisco Bay were investigated using a combination of measurement and modeling tools. Because of the inherent relationship between the physical environment and the sediment properties, the sediment properties provide a good indicator of morphologic trends. A significant finding of this...
