An atmospheric tape recorder: the imprint of tropical tropopause temperatures on stratospheric water vapor

Creator:: Mote, Philip W., Rosenlof, Karen H., McIntyre, Michael E., Carr, Ewan S, Gille, John C., Holton, James R., Kinnersley, Jonathan S., Pumphrey, Hugh C., Russell, James M., and Waters, Joe W.
Abstract:: We describe observations of tropical stratospheric water vapor q that show clear evidence of large‐scale upward advection of the signal from annual fluctuations in the effective “entry mixing ratio” qE of air entering the tropical stratosphere. In other words, air is “marked,” on emergence above the highest cloud tops, like...

A nonlocal mixing formulation for the atmospheric boundary layer

Creator:: Frech, Michael C.
Abstract:: A two-scale approach for the turbulent mixing of momentum in an unstable stratified boundary layer is proposed in an attempt to eliminate existing inconsistencies between parameterized mixing of heat and momentum. The parameterization of the large eddy stress is suitable for simple boundary layer models where computational efficiency is important....

Watershed-scale vegetation patterns in a late-successional forest landscape in the Oregon Coast Range

Creator:: Wimberly, Michael C.
Abstract:: Knowledge about vegetation patterns and ecological processes in unmanaged, late-successional watersheds is needed to provide a foundation for forest management strategies aimed at conserving native biodiversity. I examined influences of environmental variability and disturbance history on forest structure and composition in the Cummins Creek Wilderness, located on the central Oregon...

Distribution and Population Dynamics of Plant-Parasitic Nematodes in Oregon Vineyards, and Their Effects on Vine Growth [1993-1994]

Creator:: Ingham, Russell E., Strik, Bernadine C., Forge, Thomas, and Connelly, Ann
Abstract:: Objectives: 1. Survey Oregon vineyards for the presence, identity and abundance of plant parasitic nematodes. 2. Document seasonal changes in abundance of species of important plant parasites in order to identify optimum times for sampling. 3. Evaluate the efficacy of Nemacur for reducing populations of plant parasitic nematodes.

The use of foraminiferal uranium/calcium ratios as an indicator of changes in seawater uranium content

Creator:: Russell, Ann D., Emerson, Steven, Mix, Alan C., and Peterson, Larry C.
Abstract:: We examine the utility of the uranium (U) content of planktonic foraminifera tests as an indicator of past changes in seawater U content. The U/Ca ratio in foraminifera from Atlantic and Caribbean cores in constant in the Holocene and decreases by ~25% during the last glacial period. Magnesium/calcium (Mg/Ca) ratios...

Microstructure Profiles of Laser-induced Chlorophyll Fluorescence Spectra: Evaluation of Backscatter and Forward-Scatter Fiber-Optic Sensors

Creator:: Desiderio, Russell A., Cowles, Timothy J., Moum, James N., and Myrick, Michael
Abstract:: The implementation and characterization of backscatter and forward-scatter fiber-optic fluorescence sensors attached to a microstructure profiling instrument are described. By using an optical multichannel array detector to record emission spectra, eight profiles per hour of chlorophyll fluorescence spectra at 2-cm intervals can be obtained throughout the upper 100 m of...

Distribution and Population Dynamics of Plant-Parasitic Nematodes in Oregon Vineyards, and Their Effects on Vine Growth [1994-1995]

Creator:: Ingham, Russell E., Forge, Thomas, Strik, Bernadine C., and Pinkerton, J. N.
Abstract:: Objectives 1. Survey Oregon vineyards for the presence, identity and abundance of plant-parasitic nematodes. 2. Relate the distribution and abundance of potentially pathogenic species to viticultural practices and site characteristics. 3. Evaluate the efficacy of Nemacur for reducing populations of plant-parasitic nematodes. 4. Document seasonal changes in the abundance of...
