Toward understanding the nature of the soil microsite in relation to nitrogen and carbon cycling

Creator:: Cliff, John B.
Abstract:: My research has focused on understanding N and C cycling in soils at small scales. Isotope dilution methods commonly used to estimate gross rates of soil chemical transformations assume homogeneous distribution of label. I explored the effects of diffusion limitations on isotope dilution experiments in soil aggregates using spherical diffusion-reaction...

Extreme value index estimation with applications to modeling extreme insurance losses and sea surface temperatures

Creator:: Henry, John B.
Abstract:: The extreme value index (EVI) links the generalized extreme value (GEV) distribution and the generalized Pareto (GP) distribution. These two distributions are fundamental in extreme value theory (EVT), with the GEV distribution being the only possible non-degenerate limiting distribution of properly normalized maxima of iid random variables, and the GP...

Education technology to "discuss" controversial topics in large-enrollment classes within the natural resources

Creator:: Dunning, John B.
Abstract:: Introductory natural-resource courses at Purdue University are often taken by undergraduates from a wide variety of backgrounds to satisfy general science requirements. These courses therefore have large enrollments (>400 students per semester) of individuals with little background in the natural resource field. It is difficult to teach large groups of...

Measuring Capacity of the New England Otter Trawl Fleet

Creator:: Walden, John B. and Kirkley, James
Abstract:: Measurement of capacity in marine fisheries is an important activity. An economic definition of capacity is the output level corresponding to the tangency between the long-run and short-run average cost curves. A technological-engineering definition is the maximum output per unit of time provided variable inputs are unrestricted. Although cost data...

A paleomagnetic approach toward refining Holocene radiocarbon-based chronologies: Paleooceanographic records from the north Iceland (MD99-2269) and east Greenland (MD99-2322) margins

Creator:: Stoner, Joseph, Jennings, Anne, Kristjánsdóttir, Gréta B., Dunhill, Gita, Andrews, John T., and Hardardóttir, Jorunn
Abstract:: We report the intercalibration of paleomagnetic secular variation (PSV) and expanded postglacial sediment cores from geographically proximal, but sedimentologically contrasting settings. The objective is to improve relative what can be achieved with either method alone. Core MD99-2269 was taken from north Iceland shelf. Core MD99-2322 was collected from the Kangerlussuaq...

Registration of ‘Teamaker’ Hop

Creator:: Henning, John A., Haunold, Alfred, Townsend, M. Shaun, Gent, David H., and Parker, Thomas B.
Abstract:: ’Teamaker’ hop (Humulus lupulus L.) (Reg. No. CV-28, PI 558864) was developed by the USDA-ARS as a unique, nonbittering, high beta-acids hop and was released on 26 June 2006. The defining characteristics of Teamaker are its near-zero percent alpha acids levels—a distinctive condition in the Humulus species (Haunold et al.,...

Fiber optics opens window on stream dynamics

Creator:: Selker, John, van de Giesen, Nick, Westhoff, Martijn, Luxemburg, Wim, and Parlange, Marc B.
Abstract:: A new approach to monitoring surface waters using distributed fiber optic temperature sensing is presented, allowing resolutions of temperature of 0.01°C every meter along a fiber optic cable of up to 10,000 m in length. We illustrate the potential of this approach by quantifying both stream temperature dynamics and groundwater...
