We use autonomous gas measurements to examine the metabolic balance (photosynthesis
minus respiration) of coastal Antarctic waters during the spring/summer growth season. Our observations
capture the development of a massive phytoplankton bloom and reveal striking variability in pCO₂ and
biological oxygen saturation (ΔO₂/Ar) resulting from large shifts in community metabolism...

ABSTRACT
Wetlands are considered critically important in the delivery of ecosystem services such as water quality improvement, flood protection, and conservation of native biodiversity. A common measure of the effectiveness of these ecosystem services is denitrification, an anaerobic microbial process that converts nitrate (NO3-), a common water pollutant, into dinitrogen...

The thesis is a structural and petrographic study of approximately
23 square miles in the Millican SE quadrangle, Deschutes
County, Oregon. The area lies along the Brothers fault zone.
Bedrock in the area is of Pliocene to Recent age and consists
of an older basaltic unit with an associated dacite,...

Lack of growing season precipitation and the temperate climate in north central Oregon
pose challenges to growing spring wheat crops. Phosphate and sulfate fertilization can
improve early growth of spring wheat in this region and soil testing aids in determining
rates of fertilization. In this study, anion exchange membranes (AEM)...

AN ABSTRACT OF THE THESIS OF
Andrea Elizabeth Redman for the
Fish production is a source of livelihood for millions of Nigerians both as primary and secondary income provider. The study examined the economics of fish harvesting in Yola, Nigeria with the objectives of examining the socioeconomic status of the fishers, determining the gross margin of fish harvesting , examining the...
