Phytoplankton growth and diel variations in beam attenuation through individual cell analysis
… variations in red beam attenuation, the relationships between cell optical properties determined in the laboratory were applied to three diel sampling experiments in the equatorial Pacific and four in the Sargasso Sea. In the equatorial Pacific in April and October 1992, the phytoplankton biomass …

The structure of the Kuroshio west of Kyushu
… the Kuroshio west of Kyushu aboard the R/V Thompson during January, 1986 in order to investigate the water properties and flow field in the Kuroshio. A similar CTD survey was made in July, 1986 aboard the R/V Washington to study the seasonal variability in the Kuroshio. The Kuroshio in this …

Upper ocean dynamics during the LOTUS and TROPIC HEAT experiments
This thesis examines the effect of mean large-scale currents on the vertical structure of the upper ocean during two recent observational programs: the Long Term Upper Ocean Study (LOTUS) and the TROPIC HEAT experiments. The LOTUS experiment took place in the northwest Atlantic Ocean, a …

The evolution of upper ocean thermal structure at 10°N, 125°W during 1997-1998
In this thesis I have endeavored to determine the factors and physical processes that controlled SST and thermocline depth at 10°N, 125°W during the Pan American Climate Study (PACS) field program. Analysis based on the PACS data set, TOPEX/Poseidon sea surface height data, European Remote Sensing …

Scattering of the low-mode internal tide at the Line Islands Ridge
… numerical model studies, the EXITS cruise sought to observe the internal tide scattering process in the ocean for the first time. The data from three moorings equipped with moored profilers, spanning total depths of 3000-5000 m is analyzed to determine the modal content of the …

Air-sea interaction at contrasting sites in the eastern tropical Pacific : mesoscale variability and atmospheric convection at 10°N
… products. A statistically significant relationship between SST and columnar cloud liquid water (CLW), cloud reflectivity, and surface solar radiation is identified within the wavenumber-frequency band corresponding to oceanic Rossby waves. Analysis of seven years of CLW data and 20 years …

Transient structure in benthic communities : the effects of oxygen stress, burial and high rates of sedimentation
The influence of natural short-term fluctuations in environmental parameters on three components of transient benthic invertebrate community structure: abundance of individuals and species, biomass of individuals, and species diversity, were investigated in this study. The effect of low …

Wintertime convection and frontal interleaving in the Southern Ocean
… meridional heat budget. Observations made on two cruises to the APF are presented and the space-time scales of the features and thermohaline characteristics are discussed. It is suggested that double diffusive processes dominated by salt fingering are active within the intrusions. An extension of …

Nitrogen isotopes in chlorophyll and the origin of Eastern Mediterranean sapropels
The goals of this thesis were: (1) to establish methods for the determination of nitrogen and carbon isotope ratios in marine particulate and sedimentary chlorophyll derivatives; (2) to establish chlorophyll δ15N and δl3C as proxies for the nitrogen and carbon isotopic composition of marine …

Oceanic fluxes of mass, heat, and freshwater : a global estimate and perspective
Data from fifteen globally distributed, modern, high resolution, hydrographic oceanic transects are combined in an inverse calculation using large scale box models. The models provide estimates of the global meridional heat and freshwater budgets and are used to examine the sensitivity of the …
