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 ...
Cross-shelf circulation and momentum and heat balances over the inner continental shelf near Martha's Vineyard, Massachusetts
(Massachusetts Institute of Technology, 2007)
The water circulation and evolution of water temperature over the inner continental shelf are investigated using observations of water velocity, temperature, density, and bottom pressure; surface gravity waves; wind stress; ...
Low-latitude Western North Atlantic climate variability during the past millennium : insights from proxies and models
(Massachusetts Institute of Technology, 2009)
Estimates of natural climate variability during the past millennium provide a frame of reference in which to assess the significance of recent changes. This thesis investigates new methods of reconstructing low-latitude ...
The evolution of upper ocean thermal structure at 10⁰N, 125⁰W during 1997-1998
(Massachusetts Institute of Technology, 2003)
In this thesis I have endeavored to determine the factors and physical processes that controlled SST and thermocline depth at 10⁰N, 125⁰W during the Pan Amer- ican Climate Study (PACS) field program. Analysis based on the ...
A determination of air-sea gas exchange and upper ocean biological production from five noble gasses and tritiugenic helium-3
(Massachusetts Institute of Technology, 2007)
The five noble gases (helium, neon, argon, krypton, and xenon) are biologically and chemically inert, making them ideal oceanographic tracers. Additionally, the noble gases have a wide range of solubilities and molecular ...
Variability of zooplankton and sea surface temperature in the Southern Ocean
(Massachusetts Institute of Technology, 2006)
Interactions between physical and biological processes in the Southern Ocean have significant impacts on local ecosystems as well as on global climate. In this thesis, I present evidence that the Southern Ocean circulation ...
On the warm bias along the South-West African Coast in coupled models : an oceanic perspective
(Massachusetts Institute of Technology, 2008)
Coupled ocean/atmosphere simulations exhibit systematic warm biases over the South West African (SWA) coastal region. Recent investigations indicate that coastal ocean dynamics may play an important role in determining the ...
Wind, sea ice, inertial oscillations and upper ocean mixing in Marguerite Bay, Western Antarctic Peninsula : observations and modeling
(Massachusetts Institute of Technology, 2006)
Two years of moored oceanographic and automatic weather station data which span the winter ice seasons of 2001-2003 within Marguerite Bay on the western Antarctic Peninsula (wAP) shelf were collected as part of the Southern ...
Two responses of a uniformly stratified flow over a sloping bottom to a spatially varying downwelling favorable wind
(Massachusetts Institute of Technology, 2008)
The work was motivated by studies of Austin and Lentz (2002) and Pedlosky (2007). The above mentioned works considered two different responses of the stratified flow to a downwelling favorable wind forcing. The first study ...
Observations of turbulent fluxes and turbulence dynamics in the ocean surface boundary layer
(Massachusetts Institute of Technology, 2008)
This study presents observations of turbulence dynamics made during the low winds portion of the Coupled Boundary Layers and Air-Sea Transfer experiment (CBLAST-Low). Observations were made of turbulent fluxes, turbulent ...
