The front on the Northern Flank of Georges Bank in spring : 2. Cross-frontal fluxes and mixing

Creator:: Ullman, David S., Dale, Andrew C., Hebert, Dave, and Barth, John A.
Abstract:: Hydrographic observations made with an undulating vehicle carrying a CTD and concurrent shipboard ADCP velocity observations over a 12‐day period are combined to investigate vertical mixing and cross‐frontal fluxes on the Northern Flank of Georges Bank. The CTD density time series is analyzed to detect the presence of vertical overturns,...

Conservation education in free-choice learning environments : the effects of animals and interpretation

Creator:: Hodak, Eleanor
Abstract:: With 150 million people visiting accredited zoos and aquariums annually, these institutions have the unique opportunity to present conservation-oriented messages to a large and receptive audience. The purpose of this study was to explore the role of interpretation and/or the viewing of live animals in the communication of these messages....

The role of sulfur in the preservation of isoprenoid hydrocarbons in sedimentary materials of the Washington continental margin

Creator:: Pinto Alvarez, Luis A.
Abstract:: A systematic study of highly branched isoprenoids (HBI) was carried out in suspended particulate material (SPM) and Washington coastal sediments to determine their origin and fate. SPM collected at 10 m depth was filtered through Nitex membranes. C₂₅ HBI were found only in the 1.2-40 μm range over the shelf....

Changing export production in the Eastern Equatorial Pacific, 160 ka to present

Creator:: Kish, Stacy W.
Abstract:: The increase in modern atmospheric CO₂ concentration (360 ppm) from pre-industrial levels (280 ppm) raises concern over the impact of anthropogenic carbon dioxide input on atmospheric chemistry. For this reason, it is important to understand the natural fluctuations of atmospheric carbon dioxide in the past. The Vostok ice core record...

The influence of early diagenesis on trace element and molybdenum isotope geochemistry

Creator:: Poulson, Rebecca L.
Abstract:: This thesis investigates the influence of early diagenesis on trace metal and molybdenum isotope behavior in marine and lacustrine environments. Chapter one is a synthesis of previous research in all the marine environments investigated, providing an essential geochemical context for interpreting the observed behavior of Mo in these settings. Chapter...

Development of satellite bloom detection products for coastal Oregon

Creator:: McKibben, S. Morgaine
Abstract:: Two bloom-detection products were developed for the Oregon coast that describe the relative percent change observed between successive pairs of 8-day chlorophyll-a (CHL) and fluorescence line-height (FLH) products obtained from the MODerate Resolution Imaging Spectroradiometer aboard the Aqua spacecraft (MODIS-Aqua). The CHL[subscript dev] and FLH[subscript dev] products, respectively, were optimized...

Eddy correlation benthic O₂ exchange rates and characterizations of sediment properties from the central Oregon shelf at 30 meters

Creator:: McCann-Grosvenor, Kristina
Abstract:: Rates of benthic O₂ exchange are important measurements for determining organic matter remineralization, and can shed light on factors driving biogeochemical processes in coastal environments. Measurement of in situ O₂ consumption and production within permeable sediments, such as those found over ~43% of the Oregon-Washington shelf, has traditionally been done...
