The physical oceanography in the northwest Indian Ocean is largely controlled by the seasonal monsoon. The seasonal variability in circulation is complex. Many studies have investigated processes in the Persian (Arabian) Gulf and Arabian Sea, but little is understood about the Sea of Oman. This thesis incorporated observations from Argo floats, surface drifters and satellite imagery to study the deep and surface circulation in the northwest Indian Ocean. An assessment of four independent mooring...

Statistics of met-ocean conditions including wind, current and wave at the location between west and central Gulf of Mexico (GOM) are derived based on about three year of field measurements. Two-parameter Weibull distribution has been employed to fit wind speed at 10m over sea level and current speed in various depth. The joint probability contour was derived based on First-Order Reliability Method. In addition, the joint distribution of wind speed and direction was visualized by wind-rose diagr...

A transect of cores ranging from 798 m to 1585 m water depth in the South Atlantic Ocean document the relative intermediate water mass nutrient geometry and stable isotopic variability of AAIW during the Younger Dryas cooling event. The data reveal concurrent delta^13 C and delta^18 O excursions of 0.59 ppt and 0.37 ppt within the core of Antarctic Intermediate Water (AAIW) centered at 11,381 calendar years before present based on radiometric age control. A portion of the delta^1 3C variability ...

This study aims to unravel the ecological and evolutionary dynamics within the calcareous nannofossil communities at the Eocene/Oligocene (E/O) transition and during the Oligocene time when Cenozoic 'icehouse' conditions were established. The main question this study aims to answer is whether the changes in the nannofossil assemblages were controlled by intrinsic evolutionary trends or if the changes were controlled by environmental factors such as changes in temperature and nutrient availabilit...

The islands of Hawaii face increasing ground-water demands due to population growth in the last decades. Analytical and numerical models are essential tools for managing sustainable ground-water resources. The models require estimates of hydraulic properties, such as hydraulic conductivity and storage parameters. Four methods were evaluated to estimate hydraulic properties for basalts on the island of Maui. First, unconventional step-drawdown tests were evaluated. The results compare favorably w...

Thesis (Ph.D.)--University of Hawaii at Manoa, 2007. / Due to the mobility of marine vertebrates and their vast pelagic habitat, researchers have had to develop novel methods to determine the distribution, movements, and foraging behavior of top predators. The aim of this study was to apply bulk and compound-specific stable isotope analysis (CSIA) to examine the trophic dynamics and movements of tunas in the equatorial Pacific Ocean (eqPac). Yellowfin tuna collected around Hawaii displayed a rap...

Thesis (Ph.D.)--University of Hawaii at Manoa, 2008. / The implications of this work are that the DE and LA model output can be used in quantitative applications of the PacNet over the Pacific Ocean. For example, storms over the North Pacific Ocean are often poorly forecast due to the lack of observations over the ocean and insufficient initial conditions in numerical weather prediction (NWP) models. By virtue of the relationship between lightning and convective rainfall rates, PacNet data hold ...

A wave energy converter has been constructed and its function and operational characteristics have been thoroughly investigated and published. The wave energy converter was installed in March of 2006 approximately two kilometers off the Swedish west coast in the proximity of the town Lysekil. Since then the converter has been submerged at the research site for over two and a half years and in operation during three time periods for a total of 12 months, the latest being during five months of 200...

Thailand's Isthmus of Kra connects the Malay Peninsula with southern Thailand and Burma. Sixty miles in width at its narrowest point, the Kra Isthmus, over time, has been proposed as a site for the location of a canal connecting the South China Sea with the Indian Ocean. The impact that a completed Kra Canal would have on U.S. Naval policy in the Indian Ocean, in support of specific national interests, was analyzed with respect to the advantages and costs that would result from U.S. participatio...

The significance of year-round relationships between synoptic storm activity and sea-surface temperature (SST) over the North Pacific Ocean for the period January 1969 through December 1978, were examined using cross-correlation analysis. The possible existence of a seasonal dependence in the SST-wind relationships was examined using sub-sample record cross-correlation analysis and model tests with both a constant and a variable mixed-layer depth, respectively. Wind forcing data was represented ...

Bathythermograph data acquired from the research vessel USNS SILAS BENT along a meridional track in the Northeast Pacific during September 1977 were statistically analyzed to determine possible associations between the subsurface thermal structures and sea surface temperature. Strongly correlated variables (thermocline gradients, mixed layer depth, and locations of the seasonal and main thermoclines) within the vertical temperature profile were used in linear regression methods to form empirical...

The role of strong atmospheric forcing events in determining the evolution of the upper ocean during the fall and early winter cooling season was investigated. The historical series of surface and near-surface marine observations at three mid-latitude ocean weather ships (PAPA (OWS P), NOVEMBER (OWS N), and VICTOR (OWS V)) support the hypothesis that the integrated effects of these events dominate this evolution. For example, periods when the mechanical forcing was greater than the long-term mea...

An algorithm used to composite SSM/I 85.5 GHz imagery and derive sea ice motion was adapted for operational testing at Fleet Numerical Meteorology and Oceanography Command (FNMOC). A feature tracking technique was applied to a 6-month period, with data provided by FNMOC and the Naval Research Laboratory (NRL). Ice motions are detectable using the SSM/I motion algorithm, and fields of SSM/I motion vectors are qualitatively consistent with coincident fields of in situ buoy motion vectors. Accuracy...

Ocean-island flank collapses are amongst the most dangerous of all landslide related hazards in the world, as they have the potential to trigger ocean-wide tsunamis that can cause damage and loss of life to communities thousands of kilometres from their source of origin. The implications for landslide-induced tsunami originating from high volcanic islands in the Pacific are serious; and consequent hazards to life, infrastructure, and emergency management need to be constantly reviewed, monitored...

An experiment by the Naval Postgraduate School and the National Data Buoy Center was performed in the Gulf of Mexico to characterize the underwater sound generated by heavy precipitation and to determine if rainfall rates of heavy precipitation can be measured using underwater sound. During this stage of the experiment, twentytwo data sets were recorded with rainfall rates up to 340 mm/hr. For a given rainfall rate, it is found that sound levels from heavy convective precipitation are highe...

Approved for public release; distribution is unlimited / The East Greenland Current and its associated Marginal Ice Zone is a region of intense dynamical activity. A two layer, primitive equation, numerical model is used to simulate an eddy-jet interaction in the East Greenland marginal ice zone region. The effects of wind direction, topography, and sense of eddy rotation on the eddy-jet interaction are examined to determine the seaward ice transport, icebanding, and dipole formation. It ...

This dissertation combines mineralogical data and petrographic and field observations with geochemical analysis (major, trace and isotope) to provide new insights into the hydrology and geochemistry of mid-ocean ridge hydrothermal systems. Two study areas were chosen to study two different aspects of hydrothermal circulation: high-temperature on-axis hydrothermal systems were studied using samples from the Hess Deep Rift (Cocos Plate, Equatorial Pacific) and low-temperature off-axis hydrothermal...
