Emergent patterns of diversity and dynamics in natural populations of planktonic Vibrio bacteria
(Massachusetts Institute of Technology, 2005)
Despite the importance of microorganisms for global and engineering processes, currently lacking is a theoretical framework to describe how the structure of a microbial assemblage translates an environmental condition into ...
Setup in the surfzone
(Massachusetts Institute of Technology, 2007)
Surfzone wave height transformation and wave-breaking-driven increases in the mean sea level (setup) are examined on alongshore-uniform beaches with alongshore homogeneous and inhomogeneous wave forcing. While previously ...
Black carbon in marine sediments : quantification and implications for the sorption of polycyclic aromatic hydrocarbons
(Massachusetts Institute of Technology, 2003)
Sorption is a key factor in determining the fate of polycyclic aromatic hydrocarbons (PAHs) in the environment. Here, PAH sorption is proposed as the sum of two mechanisms: absorption into a biogenic, organic carbon (OC) ...
Biomimetic oscillating foil propulsion to enhance underwater vehicle agility and maneuverability
(Massachusetts Institute of Technology, 2008)
Inspired by the swimming abilities of marine animals, this thesis presents "Finnegan the RoboTurtle", an autonomous underwater vehicle (AUV) powered entirely by four flapping foils. Biomimetic actuation is shown to produce ...
Direct and indirect photoreactions of chromophoric dissolved organic matter : roles of reactive oxygen species and iron
(Massachusetts Institute of Technology, 2002)
Photochemical transformations of chromophoric dissolved organic matter (CDOM) are one of the principal processes controlling its fate in coastal waters. The photochemical decomposition of CDOM leads to the formation of a ...
Enhancement of fine particle deposition to permeable sediments
(Massachusetts Institute of Technology, 2002)
Predictions of deposition rate are integral to the transport of many constituents including contaminants, organic matter, and larvae. Review of the literature demonstrates a general appreciation for the potential control ...
Hydrodynamic controls on multiple tidal inlet persistence
(Massachusetts Institute of Technology, 2001)
Carbon nanotube synthesis and detection : limiting the environmental impact of novel technologies
(Massachusetts Institute of Technology, 2009)
Driven by commercial promise, the carbon nanotube (CNT) industry is growing rapidly, yet little is known about the potential environmental impacts of these novel materials. In particular, there are no methods to detect ...
Construction and phenotypic screening of mid-size insert marine microbial environmental genomic libraries
(Massachusetts Institute of Technology, 2008)
Functional screening of environmental genomic libraries permits the identification of clones expressing activities of interest without requiring prior knowledge of the genes responsible. In this study, protocols were ...
