Nutrient limitation dynamics of a coastal Cape Cod pond : seasonal trends in alkaline phosphatase activity
(Massachusetts Institute of Technology, 2001)
A bi-weekly seasonal study was conducted in Ashumet Pond (Cape Cod, Massachusetts). The Redfield Ratio (106C:16N:1P) and alkaline phosphatase activity (APA) were utilized in tandem as nutrient deficiency indicators (NDIs) ...
Relating behavioral context to acoustic parameters of bottlenose dolphin (Tursiops truncatus) vocalizations
(Massachusetts Institute of Technology, 2001)
This thesis presents methods to analyze the function of vocalizations of the bottlenose dolphin, Tursiops truncatus. The thesis uses the social interaction as the basic unit of analysis, and maintains a deliberate focus ...
Interactions between mantle plumes and mid-ocean ridges : constraints from geophysics, geochemistry, and geodynamical modeling
(Massachusetts Institute of Technology, 2001)
This thesis studies interactions between mid-ocean ridges and mantle plumes using geophysics, geochemistry, and geodynamical modeling. Chapter 1 investigates the effects of the Marion and Bouvet hotspots on the ultra-slow ...
Chaotic advection and mixing in a western boundary current-recirculation system : laboratory experiments
(Massachusetts Institute of Technology, 2001)
I study the exchange between a boundary current and flanking horizontal recirculations in a 'sliced-cylinder' rotating tank laboratory experiment. Two flow configurations are investigated: a single recirculation and a ...
The aggregation of clay minerals and marine microalgal cells : physicochemical theory and implications for controlling harmful algal blooms
(Massachusetts Institute of Technology, 2001)
In recent years, the use of clay minerals has emerged as one of the most promising strategies for directly controlling harmful algal blooms (HABs). Its principle is based on the mutual aggregation of algal cells and mineral ...
