Molecular and isotopic records of the combustion inputs to the environment over the last 250 yrs
(Massachusetts Institute of Technology, 2004)
The most ubiquitous source of polycyclic aromatic hydrocarbons (PAHs) to the environment is incomplete combustion. This study generated a high-resolution historical record of pyrogenic PAH emissions since pre-industrial ...
Subduction in an eddy-resolving state estimate of the northeast Atlantic Ocean
(Massachusetts Institute of Technology, 2004)
Relatively little is known about the role of eddies in controlling subduction in the eastern half of the subtropical gyre. Here, a new tool to study the eastern North Atlantic Ocean is created by combining a regional, ...
The marine geochemistry of iron and iron isotopes
(Massachusetts Institute of Technology, 2004)
This thesis addressed questions about the Fe cycle by measuring detailed profiles and transects of Fe species in the ocean and also by exploring the use of a new tracer of Fe, Fe isotopic fractionation. In the subtropical ...
