Exchanges between hemispheres and gyres : a direct approach to the mean circulation of the equatorial Pacific
An extensive set of new high-quality hydrographic data is assembled in order to determine the mean circulation in the equatorial Pacific, and thus the pathways for cross-equatorial and cross-gyre exchange. Making up the core of the data set are two onetime transpacific zonal sections nominally at …

Sedimentary lipids as indicators of depositional conditions in the coastal Peruvian upwelling regime
This thesis assesses the utility of various sedimentary lipids as indicators of short-term changes in depositional conditions and sedimentary organic matter sources in the coastal upwelling regime off of Peru. A variety of lipids (n-alkanes, n-alkanols, C37 alkenones, hopanoids, keto-ols, lycopane, …

Near-equatorial deep circulation in the Indian and Pacific oceans
Theory and observations of deep circulation in the near-equatorial Atlantic, Indian and Pacific Oceans are reviewed. Flow of deep and bottom water in the near-equatorial Indian and Pacific oceans, the two oceans with only a southern source of bottom water, is described through analysis of recent …

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 …
