Temperature and salinity variability in thermohaline staircase layers
(Massachusetts Institute of Technology, 2005)
A moored profiler record from the western tropical North Atlantic provides the first continuous time series of temperature, salinity and velocity profiles in a thermohaline staircase. Variations in the intensity of layering ...
Analyzing the effects of different types of vegetation on evapotranspiration in Big Cypress National Preserve, FL
(Massachusetts Institute of Technology, 2008)
Subsurface imaging with reverse vertical seismic profiles
(Massachusetts Institute of Technology, 2001)
This thesis presents imaging results from a 3D reverse vertical seismic profile (RVSP) dataset measured at a hydrocarbon bearing pinnacle reef in northern Michigan. The study presented many challenges in seismic data ...
A study of seismoelectric signals in measurement while drilling
(Massachusetts Institute of Technology, 2005)
An LWD acoustic wave can move the excess charge in the electric double layer along the borehole wall to generate a streaming electric field. This thesis is an experimental and theoretical investigation of the electric field ...
Nonlinear equilibration of baroclinic eddies : the role of boundary layer processes and seasonal forcing
(Massachusetts Institute of Technology, 2009)
In this thesis, the influence of boundary layer processes and seasonal forcing on baroclinic eddy equilibration is studied to understand how the baroclinic adjustment is modified when taking into account these two factors. ...
Optimal determination of global tropospheric OH concentrations using multiple trace gases
(Massachusetts Institute of Technology, 2000)
The hydroxyl radical (OH) plays a decisive role in tropospheric chemistry. Reactions with OH provide the dominant path of removal for a variety of greenhouse gases and trace species that contribute to the destruction of ...
Eddies and friction : removal of vorticity from the wind-driven gyre
(Massachusetts Institute of Technology, 2003)
Inertial terms dominate the single-gyre ocean model and prevent western-intensification when the viscosity is small. This occurs long before the oceanically-appropriate parameter range. It is demonstrated here that the ...
Establishing an unambiguous connection between grain size and style of sediment transport in the Lower Niobrara River, Nebraska, USA
(Massachusetts Institute of Technology, 2006)
The transport of sediment is often separated into two components, bedload and suspended load. This division is important because bedload has a dominant control on channel morphology while suspended load dominates the ...
The Madden-Julian oscillation and nonlinear moisture modes
(Massachusetts Institute of Technology, 2008)
The Madden-Julian oscillation (MJO), the dominant tropical intraseasonal variability with widespread meteorological impacts, continues to puzzle the climate research community on both theoretical and modeling fronts. ...
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, ...
