Molecular determination of marine iron ligands by mass spectrometry
(Massachusetts Institute of Technology, 2016)
Marine microbes produce a wide variety of metal binding organic ligands that regulate the solubility and availability of biologically important metals such as iron, copper, cobalt, and zinc. In marine environments where ...
The marine biogeochemistry of dissolved and colloidal iron
(Massachusetts Institute of Technology, 2013)
Iron is a redox active trace metal micronutrient essential for primary production and nitrogen acquisition in the open ocean. Dissolved iron (dFe) has extremely low concentrations in marine waters that can drive phytoplankton ...
Study of induced seismicity for reservoir characterization
(Massachusetts Institute of Technology, 2013)
The main goal of the thesis is to characterize the attributes of conventional and unconventional reservoirs through passive seismicity. The dissertation is comprised of the development and applications of three new methods, ...
Variations in coral reef net community calcification and aragonite saturation state on local and global scales
(Massachusetts Institute of Technology, 2013)
Predicting the response of net community calcification (NCC) to ocean acidification OA and declining aragonite saturation state [Omega]a requires a thorough understanding of controls on NCC. The diurnal control of light ...
Application of an inverse model in the community modeling effort results
(Massachusetts Institute of Technology, 1995)
Ground penetrating radar characterization of geologic structure beneath the Aberjona wetland
(Massachusetts Institute of Technology, 1999)
Ground penetrating radar (GPR) surveys are performed to determine geologic structure and to assist in the characterization and eventual modeling of ground water flow beneath the Well-H region of the Aberjona River in Woburn, ...
The thermal and metamorphic evolution of mountain belts as a response to erosion, accretion, and radiogenic heating
(Massachusetts Institute of Technology, 1999)
Simple thermal models of collisional orogenesis generally predict metamorphic temperatures that are much cooler than those revealed by thermo barometric studies of real metamorphic terrains. This thesis focuses on a more ...
Dynamics of marine zooplankton : social behavior, ecological interactions, and physically-induced variability
(Massachusetts Institute of Technology, 2008)
Marine ecosystems reflect the physical structure of their environment and the biological processes they carry out. This leads to spatial heterogeneity and temporal variability, some of which is imposed externally and some ...
Instabilities of an eastern boundary current with and without Large-scale Flow Influence
(Massachusetts Institute of Technology, 2011)
Eastern oceanic boundary currents are subject to hydrodynamic instability, generate small scale features that are visible in satellite images and may radiate westward into the interior, where they can be modified by the ...
Lead and cadmium geochemistry of corals : reconstruction of historic perturbations in the upper ocean
(Massachusetts Institute of Technology, 1986)
