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 ...
