A study of the remineralization of organic carbon in nearshore sediments using carbon isotopes
(Massachusetts Institute of Technology, 1986)
A study of the remineralization of organic carbon was conducted in the organic-rich sediments of Buzzards Bay, MA. Major processes affecting the carbon chemistry in sediments are reflected by changes in the stable carbon ...
Isotopic constraints on the sources and associations of organic compounds in marine sediments
(Massachusetts Institute of Technology, 2006)
To provide a new perspective on the fate of both natural organic matter and hydrophobic organic contaminants (HOCs) in marine sediments, we have investigated the relationship between radiocarbon (14C) age and the different ...
Mechanisms of metal release from contaminated coastal sediments
(Massachusetts Institute of Technology, 2005)
The fate of trace metals in contaminated coastal sediments is poorly understood, yet critical for effective coastal management. The aim of this thesis is to investigate and quantify the mechanisms leading to the release ...
Tropical climate variability from the last glacial maximum to the present
(Massachusetts Institute of Technology, 2005)
This thesis evaluates the nature and magnitude of tropical climate variability from the Last Glacial Maximum to the present. The temporal variability of two specific tropical climate phenomena is examined. The first is the ...
Vertical flux, ecology and dissolution of radiolaria in tropical oceans : implications for the silica cycle
(Massachusetts Institute of Technology, 1982)
Radiolarians which settle through the oceanic water column were recovered from three stations (western Tropical Atlantic-Station E, central Tropical Pacific-P1 and Panama Basin-PB) using PARFLUX sediment traps in moored ...
