Deep explosive volcanism on the Gakkel Ridge and seismological constraints on Shallow Recharge at TAG Active Mound
(Massachusetts Institute of Technology, 2013)
Seafloor digital imagery and bathymetric data are used to evaluate the volcanic characteristics of the 85°E segment of the ultraslow spreading Gakkel Ridge (9 mm yr-¹). Imagery reveals that ridges and volcanic cones in the ...
Advances in measurements of particle cycling and fluxes in the ocean
(Massachusetts Institute of Technology, 2013)
The sinking flux of particles is an important removal mechanism of carbon from the surface ocean as part of the biological pump and can play a role in cycling of other chemical species. This work dealt with improving methods ...
Marine microbial intact polar diacylglycerolipids and their application in the study of nutrient stress and bacterial production
(Massachusetts Institute of Technology, 2013)
Intact polar diacylglycerolipids (IP-DAGs) were used to study microbial dynamics in the surface ocean. IP-DAGs from surface ocean seawater were quantified using high performance liquid chromatography-mass spectrometry ...
Distribution, growth, and transport of larval fishes and implications for population dynamics
(Massachusetts Institute of Technology, 2021)
The early life stages of marine fishes play a critical role in population dynamics, largely due to their high abundance, high mortality, and ease of transport in ocean currents. This dissertation demonstrates the value of ...
