Relative sea-level rise and the development of channel-fill and shallow-water sequences on Cape Cod, Massachusetts
(Massachusetts Institute of Technology, 1999)
Channel-fill sediments located in shallow-water off the south shore of Cape Cod, Massachusetts, provide a record of the late-Pleistocene and Holocene geological evolution in a post-glacial setting. Though conventionally ...
Recent relative sea-level change in Eastern North America
(Massachusetts Institute of Technology, 1987)
Marine sedimentary organic matter: delineation of marine and terrestrial sources through radiocarbon dating; and the role of organic sulfur in early petroleum generation
(Massachusetts Institute of Technology, 1996)
This thesis details two years of research conducted with the guidance and support of three advisors: Dr. J. K. Whelan, Dr. J. S. Seewald and Dr. T. I. Eglinton. Each of the three chapters represents a different, self-contained ...
The evolution of upper ocean thermal structure at 10⁰N, 125⁰W during 1997-1998
(Massachusetts Institute of Technology, 2003)
In this thesis I have endeavored to determine the factors and physical processes that controlled SST and thermocline depth at 10⁰N, 125⁰W during the Pan Amer- ican Climate Study (PACS) field program. Analysis based on the ...
Diagnosis of physical and biological controls on phytoplankton distribution in the Gulf of Maine-Georges Bank region
(Massachusetts Institute of Technology, 1999)
The linkage between physics and biology is studied by applying a one-dimensional model and a two-dimensional model to the Sargasso Sea and the Gulf of Maine- Georges Bank region, respectively. The first model investigates ...
Paleoceanographic variability on a millennial scale: a high resolution record of the latest deglaciation from the Blake Outer Ridge, western North Atlantic
(Massachusetts Institute of Technology, 1998)
Mass, heat, oxygen and nutrient fluxes at 30s̊ and their implications for the Pacific-Indian through flow and the global heat budget
(Massachusetts Institute of Technology, 1991)
Meridional circulation in the tropical North Atlantic
(Massachusetts Institute of Technology, 1992)
Injection and movement of Tritium-³He in the Northeastern Atlantic
(Massachusetts Institute of Technology, 1999)
This thesis describes an attempt to build a box model of the circulation in the eastern North Atlantic and to use it with transient tracer data to infere rates of ventilation in the subtropcial thermocline. The starting ...
Sulfate in foraminiferal calcium carbonate : investigating a potential proxy for sea water carbonate ion concentration
(Massachusetts Institute of Technology, 1988)
The sulfur content of planktonic and benthic foraminifera was measured in specimens recovered from deep-sea sediment cores and individuals grown in culture. A new method for measuring sulfur in foraminiferal calcium carbonate ...
