Oceanic phosphorus imbalance : magnitude of the mid-ocean ridge flank hydrothermal sink

Creator:: Wheat, C. Geoffrey, McManus, James, Mottl, Michael J., and Giambalvo, Emily
Abstract:: We present a new estimate for the crustal phosphorous sink that results from reactions among seawater, basalt, and sediment blanketing low temperature mid-ocean ridge flank hydrothermal systems. New estimates for global hydrothermal power output, sediment thickness, and the dissolved phosphate concentrations in basement formation fluids indicate that fluid flow through...

Ecophysiological interpretation of oxygen consumption rates and enzymatic activities of deep-sea copepods

Creator:: Thuesen, Erik V., Miller, Charles B., and Childress, James J.
Abstract:: We measured oxygen consumption rates, the activities of citrate synthase (CS) and lactate dehydrogenase (LDH) and protein contents for over 30 species of deep-sea pelagic Copepoda. The lowest oxygen consumption rates were measured in Euaugaptilus magnus and the highest rates were measured in Paraeuchaeta tonsa. Weight-specific oxygen consumption rates declined...

Model Studies of Near-Inertial Waves in Flow over the Oregon Continental Shelf

Creator:: Federiuk, J. and Allen, J. S.
Abstract:: Two-dimensional, primitive equation model studies of wind-forced flow over a continental shelf Show that, under upwelling conditions, high levels of near-inertial wave energy are found in the interior over the shelf. The regions of elevated wave energy, with maximum wave amplitudes of around ±0.2 m s⁻¹, persist for up to...

A comprehensive approach for habitat restoration in the Columbia Basin

Creator:: Rieman, Bruce E., Smith, Courtland L., Naiman, Robert J., Ruggerone, Gregory T., Wood, Christ C., Huntly, Nancy, Merril, Erik N., Alldredge, J. Richard, Bisson, Peter A., Congleton, James, Fausch, Kurt D., Levings, Colin, Pearcy, William, Scarnecchia, Dennis, and Smouse, Peter
Abstract:: The Columbia Basin once supported a diversity of native fishes and large runs of anadromous salmonids that sustained substantial fisheries and cultural values. Extensive land conversion, watershed disruptions, and subsequent fishery declines have led to one of the most ambitious restoration programs in the world. Progress has been made, but...

Non-regulatory efforts to combat nonpoint source pollution in Oregon

Creator:: Lindberg, Roberta J.
Resource Type:: Capstone Project

Identification of layered cloud occurrences from the Lidar In-Space Technology Experiment and advanced very high resolution radiometer imagery

Creator:: Stevermer, Amy J.
Abstract:: Realistic assessment of the vertical distribution of clouds, particularly the occurrence of multi-layered systems, is critical for accurate calculations of radiative transfer in general circulation models. Such information is also useful in the design and improvement of satellite retrieval techniques. Current methods for retrieving cloud properties from satellite data assume...

Decomposition of absorption coefficients and decorrelation lengthscales of hydrographic and inherent optical properties in the Middle Atlantic Bight

Creator:: Simeon, Jennifer J.
Abstract:: This investigation is an exploration of the use of inherent optical properties towards further elucidation of coastal circulation processes occurring on the continental shelf and slope in the Middle Atlantic Bight, south of Cape Cod Massachusetts, during 14-Aug to 1-Sep 1996 and 25-Apr to 15-May 1997. Assessing the possibility of...

Hydrothermal links between ocean plateau formation and global anoxia at the Cenomanian-Turonian boundary

Creator:: Snow, Laura J.
Abstract:: The Cretaceous was a period of extreme climatic conditions accompanied by major perturbations in ocean-atmosphere biogeochemical cycles. One of the most intriguing features is the sporadic interruption of normal marine pelagic sediment deposition by organic rich sediments deposited during oxygen-deficient conditions (ocean anoxic events OAEs). A current model for the...

Late pleistocene changes in the Peru current based on planktonic foraminifera

Creator:: Feldberg, Melissa J.
Abstract:: Planktonic foraminiferal faunal assemblages were used to estimate sea-surface temperatures (SST) in the southeast Pacific Ocean during the Last Glacial Maximum (LGM) and off the coast of Peru over the last 150,000 years. Temperatures along the eastern boundary of South America were 6-8° C cooler during the LGM than at...
