Interpretation of equatorial current meter data as internal waves
(Massachusetts Institute of Technology, 1987)
The biogeochemistry of cobalt in the Sargasso Sea
(Massachusetts Institute of Technology, 2001)
Processes that enable marine phytoplankton to acquire trace metals are fundamental to our understanding of primary productivity and global carbon cycling. This thesis explored the biogeochemistry of cobalt using analytical ...
The marine biogeochemistry of molybdenum
(Massachusetts Institute of Technology, 2003)
Prevailing wisdom holds that the vertical distribution of molybdenum (Mo) in the open ocean is conservative, despite Mo's important biological role and association with Mn oxides and anoxic sediments. Mo is used in both ...
Large scale oceanic circulation and fluxes of freshwater, heat, nutrients and oxygen
(Massachusetts Institute of Technology, 2000)
A new, global inversion is used to estimate the large scale oceanic circulation based on the World Ocean Circulation Experiment and Java Australia Dynamic Experiment hydrographic data. A linear inverse "box" model is used ...
Uranium-series radionuclide records of paleoceanographic and sedimentary changes in the Arctic Ocean
(Massachusetts Institute of Technology, 2009)
The radionuclides ²³¹Pa and ²³⁰Th, produced in the water column and removed from the ocean by particle scavenging and burial in sediments, offer a means for paleoceanographers to examine past dynamics of both water column ...
Linear and nonlinear Rossby waves in basins both with and without a thin meridional barrier
(Massachusetts Institute of Technology, 2002)
The linear and nonlinear Rossby wave solutions are examined in homogeneous square basins on the [beta]-plane both with and without a thin meridional barrier. In the presence of the meridional barrier the basin is almost ...
A scientific framework for evaluating coral reef resilience to climate change
(Massachusetts Institute of Technology, 2016)
The 21st century warming and acidification of tropical oceans will impact the structure and function of coral reef ecosystems. Consequently, conservation efforts are increasingly focused on identifying and protecting reef ...
Seismic and numerical constraints on the formation and evolution of ocean lithosphere
(Massachusetts Institute of Technology, 2019)
This thesis explicates aspects of the basic structure of oceanic lithosphere that are shaped by the processes that form the lithosphere. The strength of lithospheric plates relative to the underlying mantle enables the ...
Decoupling of iron and phosphate in the global ocean
(Massachusetts Institute of Technology, 2003)
Iron (Fe) is an essential micronutrient for marine phytoplankton often limiting phytoplankton growth due to its low concentration in the ocean and thus playing a role in modulating the ocean's biological pump. In order to ...
Abyssal mixing from bottom boundary effects in Mid-Atlantic Ridge flank canyons
(Massachusetts Institute of Technology, 2010)
This paper begins to explore a previously neglected mechanism for abyssal ocean mixing using bottom boundary layer dynamics. Abyssal mixing and the associated upward buoyancy fluxes are necessary to balance the sinking of ...
