The Teakettle Ecosystem Experiment in the southern Sierra Nevada is using thinning and prescribed
fire to recreate historical stand conditions. As part of Teakettle we assessed pretreatment diversity and density
of the soil arthropod community in 1998 and 2000. We determined the density and diversity of soil microarthropods
among treatment...
A method for predicting oceanic productivity from remotely sensed diffuse attenuation (488 nm) and
surface chlorophyll concentration is presented. The method uses a climatological approach which consists
of applying a set of regressions for each region and season to yield the depth of the chlorophyll maximum,
the exponential slope of...
The thesis was an investigation into the mechanism of precipitation
from solid solution in an Aluminum-0.7% Magnesium-0.6%
Silicon alloy containing iron impurities. Laue x-ray diffraction patterns
were obtained from solution heat treated and aged single crystal
specimens in various crystallographic orientations. Precipitation
related streaking was detected on some of the...
Over the past fifteen years, the market for bluefin tuna has evolved in an attempt to further enhance the economic value of bluefin tuna landings. Historically, the US East Coast has been a major supplier of high quality bluefin tuna to Japan, the primary market for sashimi grade tuna. To...
Three speakers give their impressions of the conference with praise as well as suggestions for the future. The inter-disciplinary nature of the conference was praised as wellas the attempt to integrate non-economists and those outside of the academy. One suggested that fisheries cannot be properly understood and cannot be properly...
The increasing demand for shark fins in Asia and the shark s life history pattern of slow growth, late maturity, and
few offspring, have generated concerns regarding the sustainability of shark resources. Despite this concern, little effort has
been spent on understanding the markets for shark fin products and the...
The only two seafood commodities traded in futures markets are frozen white and black tiger shrimps on the
Minneapolis Grain Exchange (MGE). These two contracts, however, have failed to attract the expected trade volume based on
the underlying shrimp cash market flow. First, we investigate the hedging effectiveness of these...
Infrared radiometers, photographs, and a multispectral
scanner were used in a remote sensing study of the ocean off
Oregon during the summer of 1969. Upwelling appeared on
infrared temperature maps as a zone of cold water along the
coast and Columbia River water appeared as a warm water
"plume". Sharp...
