The paleoceanography of the Bering Sea during the last glacial cycle
(Massachusetts Institute of Technology, 2006)
In this thesis, I present high-resolution stable-isotope and planktonic-fauna records from Bering Sea sediment cores, spanning the time period from 50,000 years ago to the present. During Marine Isotope Stage 3 (MIS3) at ...
Biogeochemical applications of compound-specific radiocarbon analysis
(Massachusetts Institute of Technology, 2000)
Compound-specific carbon isotopic (613C and A14C) data are reported for lipid biomarkers isolated from Santa Monica Basin (SMB) and Santa Barbara Basin (SBB) surface sediments. These organic compounds represent phytoplanktonic, ...
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 ...
Trace metals and the ecology of marine cyanobacteria
(Massachusetts Institute of Technology, 2000)
The marine cyanobacteria Synechococcus and Prochlorococcus are important primary producers in oligotrophic oceans. The abundance and cell division rates of these cyanobacteria can be influenced by trace metals such as iron ...
