Hydrological and biogeochemical cycling along the Greenland ice sheet margin
(Massachusetts Institute of Technology, 2012)
Global warming has led to a significant increase in Greenland ice sheet (GrIS) melt and runoff since 1990, resulting in escalated export of fresh water and associated sediment to the surrounding North Atlantic and Arctic ...
Earthquake behavior and structure of oceanic transform faults
(Massachusetts Institute of Technology, 2012)
Oceanic transform faults that accommodate strain at mid-ocean ridge offsets represent a unique environment for studying fault mechanics. Here, I use seismic observations and models to explore how fault structure affects ...
The centennial and millennial variability of the IndoPacific warm pool and the Indonesian Throughflow
(Massachusetts Institute of Technology, 2012)
As the only low-latitude connection between ocean basins, the Indonesian Throughflow allows the direct transmission of heat and salinity between the Pacific and Indian Oceans. Despite its potential importance, the role of ...
Constraining circulation changes through the last deglaciation with deep-sea coral radiocarbon and sedimentary ²³¹Pa/²³⁰Th
(Massachusetts Institute of Technology, 2012)
Radioactive isotopes can be used in paleoceanography both for dating samples and as tracers of ocean processes. Here I use radiocarbon and uranium series isotopes to investigate the ocean's role in climate change over the ...
Comprehensive study of a heavy fuel oil spill : modeling and analytical approaches to understanding environmental weathering
(Massachusetts Institute of Technology, 2012)
Driven by increasingly heavy oil reserves and more efficient refining technologies, use of heavy fuel oils for power generation is rising. Unlike other refined products and crude oils, a large portion of these heavy oils ...
The effects of ocean eddies on tropical cyclones
(Massachusetts Institute of Technology, 2012)
The purpose of this study is to understand the interactions of tropical cyclones with ocean eddies. In particular we examine the influence of a cold-core eddy on the cold wake formed during the passage of Typhoon Fanapi ...
Aridification of the Indian subcontinent during the Holocene : implications for landscape evolution, sedimentation, carbon cycle, and human civilizations
(Massachusetts Institute of Technology, 2012)
The Indian monsoon affects the livelihood of over one billion people. Despite the importance of climate to society, knowledge of long-term monsoon variability is limited. This thesis provides Holocene records of monsoon ...
