Geophysical characterization of the effects of fractures and stress on subsurface reservoirs
(Massachusetts Institute of Technology, 2013)
We study the effect of fractures on reservoir characterization and subsurface rock property measurements using seismic data. Based on the scale of a fracture relative to seismic wavelength, we divide the dissertation into ...
Isentropic diagnostics of mid-latitude circulation and transport
(Massachusetts Institute of Technology, 2001)
This thesis examines the mid-latitude circulation and tracer transport using zonal average isentropic diagnostics. The Underworld (i.e. the region roughly below the 300K-isentrope) is targeted by our research. Currently, ...
Imaging of structure at and near the core mantle boundary using a generalized radon transform
(Massachusetts Institute of Technology, 2007)
In this thesis, concepts from inverse scattering and modem statistics are combined into a powerful tool for imaging interfaces in Earth's deep interior. Specially, a generalized Radon transform (GRT) approach is developed ...
Mechanistic models of oceanic nitrogen fixation
(Massachusetts Institute of Technology, 2009)
Oceanic nitrogen fixation and biogeochemical interactions between the nitrogen, phosphorus and iron cycles have important implications for the control of primary production and carbon storage in the ocean. The biological ...
Seismic characterization of fractured reservoirs (part I) ; Crustal deformation in the Tibetan Plateau (part II)
(Massachusetts Institute of Technology, 1999)
(PART I) In this thesis, we study the possibility of using P-waves to investigate properties of fractured reservoirs and the diagnostic ability of the P-wave seismic data to detect fractures. The objectives of this thesis ...
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 ...
The biogeochemistry and residual mean circulation of the southern ocean
(Massachusetts Institute of Technology, 2005)
I develop conceptual models of the biogeochemistry and physical circulation of the Southern Ocean in order to study the air-sea fluxes of trace gases and biological productivity and their potential changes over ...
