Variability in mesoscale circulation and its effects on zooplankton distribution in the Northern California Current

Creator:: Keister, Julie Eileen
Abstract:: In eastern boundary current upwelling ecosystems, mesoscale circulation features such as eddies and upwelling filaments play a prominent role in the transfer of water and the associated plankton from the productive nearshore to the oligotrophic deep sea. The relationship between mesoscale circulation, zooplankton distributions, and the across-shelf transport of coastal...

Community-based sea turtle monitoring and management at Helen Reef, Hatohobei State, Republic of Palau

Creator:: Barr, Julie M.
Abstract:: Remote areas are frequently homes to regional subpopulations of endangered green sea turtles (Chelonia mydas) and their essential habitat. Local communities are often the users and primary stewards of this valuable and charismatic resource. Recognizing this, a Hatohobeian community group in Palau has engaged in longterm monitoring and conservation management...

Phosphorus control of nitrogen fixation

Creator:: Watkins-Brandt, Katie S.
Abstract:: Under conditions of fixed N-limitation, as with most oligotrophic systems, the process of biological N₂ fixation (diazotrophy) is favored, provided the necessary trace elements and vitamins are sufficient. Despite the well understood contributions of N₂ fixation in oligotrophic regions, the nutritional and ecological controls of marine diazotrophs have not been...

Comparison of radiative feedback variability over multiple time scales in climate model and reanalysis data

Creator:: Dalton, Meghan M.
Abstract:: In a steady state, the Earth's absorbed solar radiation (ASR) balances the outgoing longwave radiation (OLR) at the top of the atmosphere (TOA). In response to a radiative forcing, that is, an external perturbation to the top of the atmosphere energy balance, the Earth's climate system adjusts until reaching a...

Summertime Influence of SST on Surface Wind Stress off the U.S. West Coast from the U.S. Navy COAMPS Model

Creator:: Haack, Tracy, Chelton, Dudley, Pullen, Julie, Doyle, James D., and Schlax, Michael
Abstract:: High-resolution mesoscale model sea surface temperature (SST) analyses and surface wind stress forecasts off the U.S. West Coast are analyzed on monthly time scales for robust signatures of air–sea interaction as the surface winds encounter ocean surface features such as SST fronts, filaments, and eddies. This interaction is manifest by...

Retrieval of cloud droplet size from visible and microwave radiometric measurements during INDOEX: Implication to aerosols’ indirect radiative effect

Creator:: Liu, Guosheng, Shao, Hongfei, Coakley, James A., Curry, Judith A., Haggerty, Julie A., and Tschudi, Mark A.
Abstract:: The effective radius of water cloud droplets is retrieved using remotely sensed passive microwave and visible data collected by aircraft during the Indian Ocean Experiment. The purpose of this study is to assess the aerosols’ effect on cloud microphysical and radiative properties. To study this effect, we investigate the relationships...

Comparative study of the population dynamics, secondary productivity, and reproductive ecology of the euphausiids Euphausia pacifica and Thysanoessa spinifera in the Oregon upwelling region

Creator:: Gutierrez, Jaime Gomez
Abstract:: I compare the seasonal abundance variation, population dynamics, fecundity, egg hatching mechanism and success, and apostome ciliate parasites of the euphausiids Euphausia pac?fica and Thysanoessa spinfera from the Oregon coast, USA. Community structure and nearshore distributions were examined from bi-weekly oceanographic surveys (1970-1972). This region has a strong cross-shelf change...

A satellite-derived climatology of global ocean winds

Creator:: Risien, Craig Miller
Abstract:: A satellite-derived Climatology of Global Ocean Winds (COGOW) on a 0.5° latitude by 0.5° latitude grid is presented based on 5-years (August 1999 July 2004) of measurements from the SeaWinds scatterometer that was launched on 19 June 1999 onboard the QuikSCAT satellite. SeaWinds is an active microwave radar that estimates...

Two coastal upwelling domains in the northern California Current system

Creator:: Huyer, Adriana, 1945-, Fleischbein, Jane, Keister, Julie Eileen, Kosro, P. Michael, 1951-, Perlin, Natalie, Smith, Robert L. (Robert Lloyd), 1935-, and Wheeler, Patricia A.
Abstract:: A pair of hydrographic sections, one north and one south of Cape Blanco at 42.9N, was sampled in five summers (1998–2000 and 2002–2003). The NH line at 44.6N lies about 130 km south of the Columbia River, and spans a relatively wide shelf off Newport, Oregon. The CR line at...

Dynamics of organic matter production and degradation during coastal diatom blooms

Creator:: Wetz, Michael S.
Abstract:: Experiments were designed to answer key questions about diatom-derived organic matter cycling (i.e., production and degradation) in coastal systems. Dissolved organic matter (DOM) production was examined in axenic batch cultures of five diatom species. Dissolved organic carbon (DOC) release rates varied between species, but were significantly higher for all species...
