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 ...
The gravity field and plate boundaries in Venezuela
(Massachusetts Institute of Technology, 1972)
Free-air and simple Bouguer anomaly maps of the Venezuelan continental margin (from 60°W to 72°W and from 7°N to 13°N) are presented. The major features of the free-air map are: the large lows associated with the deep ...
Analysis and interpretation of tidal currents in the coastal boundary layer
(Massachusetts Institute of Technology, 1979)
Concern with the impact of human activities on the coastal region of the world's oceans has elicited interest in the so-called "coastal boundary layer"-that band of water adjacent to the coast where ocean currents adjust ...
