The Southern Ocean at the last glacial maximum : a strong sink for atmospheric carbon dioxide

Creator:: Moore, J. Keith, Abbott, Mark R., Richman, James G., and Nelson, David M.
Abstract:: Analysis of satellite ocean color, sea surface temperature, and sea ice cover data reveals consistent patterns between biological production, iron availability, and physical forcings in the Southern Ocean. The consistency of these patterns, in conjunction with information on physical conditions during the last glacial maximum (LGM), enables estimates of export...

Phytoplankton chlorophyll distibutions and primary production in the Southern Ocean

Creator:: Moore, J. Keith and Abbott, Mark R.
Abstract:: Satellite ocean color data from the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) were used to examine distributions of chlorophyll concentration within the Southern Ocean for the period of October 1997 through September 1998. Over most of the Southern Ocean, mean chlorophyll concentrations remained quite low (<0.3-0.4 mg m¯³). Phytoplankton blooms where...

Physical and chemical factors controlling the distribution of the major phytoplankton classes at the Antarctic Polar Front, 170 °W

Creator:: Mengelt, Claudia
Abstract:: This study was part of the Antarctic Environment and Southern Ocean Study (AESOPS) program, whose main goal was to investigate the role of the biota in the carbon flux from the atmosphere to the interior of the ocean. We quantified the abundance of the major phytoplankton classes and examined the...

Initiation of the spring phytoplankton increase in the Antarctic Polar Front Zone at 170°W

Creator:: Landry, Michael R., Brown, Susan L., Selph, Karen E., Abbott, Mark R., Letelier, Ricardo M., Christensen, Stephanie, Bidigare, Robert R., and Casciotti, K.
Abstract:: During austral summer 1997, satellite imagery revealed enhanced chlorophyll associated with the Antarctic Polar Front at 170°W. Phytoplankton growth conditions during the early stages of the spring increase were investigated on the Antarctic Environment and Southern Ocean Process Study Survey I cruise using flow cytometry (FCM) and microscopy to characterize...

The re-discovery of soul and reclamation of spirit anew : the influence of spirituality on the persistence of Mexican American Chicana (o) community college transfer students at a small liberal arts university

Creator:: Rasca-Hidalgo, Leo
Abstract:: Low completion rates have created serious "leakage points" (Astin, 1988) and "severe hemorrhaging" (Lango, 1996) in higher education to a large number of Hispanics. Traditional research on college persistence, which has blamed the students' culture for low performance, is inaccurate. Little research has specifically investigated academic persistence from a cultural...

Long baroclinic planetary waves in a nonzonal vertically sheared mean flow

Creator:: Cerovecki, Ivana
Abstract:: We consider long planetary waves of annual period linearized about a steady, wind-driven subtropical (ST) gyre circulation. The circulation divides the gyre into an eastern zone (EZ) where only the surface layer is in steady motion and a western zone (WZ) where both the surface and the middle layer are...

Production and partitioning of organic matter during simulated phytoplankton blooms

Creator:: Wetz, Michael S. and Wheeler, Patricia A.
Abstract:: Few studies have examined the partitioning of organic matter in upwelling systems, despite the fact that these systems play a key role in carbon and nitrogen budgets in the ocean. We examined the production and partitioning of phytoplankton-derived organic matter in deck incubations off Oregon during the upwelling season. During...

A cognitive-motivational-relational examination of angry driving : applying Lazarus' model to a public health concern

Creator:: Flint, Matthew O.
Abstract:: Angry driving behaviors that lead to acts of road rage have become a major public health concern. Understanding the differences between people who drive with a high level of anger and those who do not provides insight into possible prevention approaches. This study applied Richard Lazarus' Cognitive-Motivational-Relational (CMR) Model to...
