Nitrogen and chlorophyll relations to low altitude photographed reflectance of perennial ryegrass

Creator:: Kreinheder, David P.
Abstract:: This study was conducted to test a photographic method of determining the relationship, if any, between the spectral reflectance and measured levels of nitrogen and chlorophyll in plots of ryegrass turf. Color and color infrared aerial photos were taken of a grid of 375 plots of ryegrass in June and...

Implementation of a Java Graphical User Interface for the Visual Programming Language Forms/3

Creator:: Hackenyos, David P.
Abstract:: The visual programming language Forms/3 currently uses a graphical user interface implemented in Garnet. Garnet was developed by the User Interface Software Group in the Human Computer Interaction Institute at Carnegie Mellon University, but is no longer supported. This paper presents an implementation of a user interface for Forms/3 written...

Nonlinear formation of holographic images of obscurations in laser beams

Creator:: Widmayer, C. Clay, Milam, David, and de Szoeke, Simon P.
Abstract:: Computer models are used to simulate the nonlinear formation of images of obscurations in laser beams. The predictions of the model are found to be in good agreement with measurements conducted in the nonlinear regime corresponding to a typical solid-state laser operation. In this regime, peak-to-mean fluence ratios large enough...

Sr-Nd-Pb isotope geochemistry of leg 144 West Pacific guyouts: Implications for the geochemical evolution of the "SOPITA" mantle anomaly

Creator:: Koppers, Anthony A. P., Staudigel, Hubert, Christie, David M., Dieu, Julie J., and Pringle, Malcolm S.
Abstract:: The Sr, Nd, and Pb isotopic compositions of five Cretaceous guyots (Limalok, Lo-En, Wodejebato, MIT, and Takuyo-Daisan) within the West Pacific Seamount Province (WPSP) indicate that they originated from geochemically enriched mantle sources. They are characterized by large isotopic variations in Pb (²⁰⁶Pb/²⁰⁴Pb = 18.58-19.80, ²⁰⁷Pb/²⁰⁴Pb = 15.55-15.68, and ²⁰⁸Pb/²⁰⁴Pb...

Evidence of a dissolution effect on benthic foraminiferal shell chemistry: δ¹³C, Cd/Ca, Ba/Ca, and Sr/Ca results from the Ontong Java Plateau

Creator:: McCorkle, Daniel C., Martin, Pamela A., Lea, David W., and Klinkhammer, Gary P.
Abstract:: Core-top benthic foraminifera (Cibicidoides wuellerstorfi) from a depth transect of Soutar box cores from the Ontong-Java Plateau (1.6 – 4.4 km) were analyzed for cadmium, barium, and strontium (Cd/Ca, Ba/Ca, and Sr/Ca) and for their stable isotopic composition (δ¹³C and δ¹⁸O). We also measure bottom water δ¹³C, Cd, and Ba...

Water mass subduction and the transport of phytoplankton in a coastal upwelling system

Creator:: Washburn, Libe, Kadko, David C., Jones, Burton H., Hayward, Thomas, Kosro, P. Michael, 1951-, Stanton, Timothy P., Ramp, Steve, and Cowles, Timothy
Abstract:: Observations during the Coastal Transition Zone (CTZ) experiment in summer 1988 reveal the presence of deep phytoplankton layers in a coastal upwelling system. The layers occur throughout the CTZ study area, including a strong baroclinic jet which was present over the period of the experiment. On the basis of a...

New Directions in Earth Observing: Scientific Applications ofMultiangle Remote Sensing

Creator:: Diner, David J., Asner, Gregory P., Davies, Roger, Knyazikhin, Yuri, Muller, Jan-Peter, Nolin, Anne W., Pinty, Bernard, Schaaf, Crystal B., and Stroeve, Julienne
Abstract:: The physical interpretation of simultaneous multiangle observations represents a relatively new approach to remote sensing of terrestrial geophysical and biophysical parameters. Multiangle measurements enable retrieval of physical scene characteristics, such as aerosol type, cloud morphology and height, and land cover (e.g., vegetation canopy type), providing improved albedo accuracies as well...
