Paleo-oceanography of the subtropical southeastern Pacific during late Quaternary : a study of radiolaria, opal and quartz contents of deep-sea sediments

Creator:: Molina-Cruz, Adolfo
Abstract:: Micropaleontological data have been analyzed through mathematical and statistical procedures, in order to: (1) establish the distribution pattern of radiolarian assemblages in the surface sediments, (2) establish the relationship of these assemblages with oceanographic variables, (3) determine the faunal composition down-core with respect to the faunal surface pattern, and (4)...

The influence of herbivore generated inputs on nutrient cycling and soil processes in a lower montane tropical rain forest of Puerto Rico

Creator:: Fonte, Steven J.
Abstract:: The role of insect herbivores in the nutrient cycling dynamics of forest ecosystems remains poorly understood. Although past research in herbivory has focused primarily on the deleterious effects that insects can have on tree growth and mortality, the overall effects of herbivory are more complex. Herbivores have the potential to...

The sediment response of a dissipative beach to variations in wave climate

Creator:: Haxel, Joseph H.
Abstract:: Using wave and wind data from nearby buoys and gauges, real time kinematic global positioning system (RTK-GPS) and light detection and ranging (lidar) topographic survey data, and a robust video record, we have quantified the Large Scale Coastal Behavior (LSCB) of a dissipative end member beach in the Pacific Northwest....

Sedimentation within the Cocos Gap, Panama Basin

Creator:: Dowding, Lynn Gretton
Abstract:: The Cocos Gap is a deeper portion, or saddle, of the Cocos Ridge and forms part of the western boundary of the Panama Basing It is probably typical of saddles within most submarine ridges, In order to determine the mechanisms controlling sediment dispersal, the nature and sources of the sediments...

Offshore controls on nearshore circulation

Creator:: Long, Joseph W.
Abstract:: The rip current field resulting from the transformation of surface gravity waves over offshore submarine canyons is studied. Employing a wave transformation model and a wave-induced circulation model over observed bathymetry we find that rip current circulation cells exist with alongshore spacing of O(1OOm) even though the nearshore bathymetry displayed...

Nearshore wave predictions along the Oregon and southwest Washington coast

Creator:: García-Medina, Gabriel
Abstract:: This thesis contains a manuscript describing the implementation of a high resolution wave forecasting model for the coasts of Washington and Oregon. The purpose of this project was to advance the wave predictive capabilities of the states of Oregon and the southwest part of Washington by including the effects of...

Biogenic silica sedimentation in the central equatorial Pacific during the Cenozoic

Creator:: Leinen, Margaret, 1946-
Abstract:: A new technique for determining the amount of opal in deep-sea sediments of any age is described. Using a normative calculation, a portion of the analytical silica concentration of sediments is subtracted as non-biogenic in proportion to the concentration of aluminum in the sample. The ratio of SiO₂:Al₂O₃ used to...

Nearshore hydrodynamic model comparisons and predictions of bathymetric evolution

Creator:: Lescinski, Jamie M.
Abstract:: The surf zone exhibits large energetic signals from wave shoaling and subsequent dissipation due to breaking, forcing circulation. The bathymetry responds to the wave and wave-induced circulation with the growth, transport, and destruction of large scale bathymetric features, such as mega ripples and sand bars. There is an obvious fluctuation...

Simulating extreme total water levels using a time-dependent, extreme value approach

Creator:: Serafin, Katherine A.
Abstract:: Coastal flood hazard zones and the design of coastal defenses are often devised using either the maximum recorded total water level (TWL) or a 'design' event such as the 100-year return-level flood, usually projected from observed extreme events. Despite technological advances driving more consistent instrumental records of wave heights and...
