Abstract : The operational goals of this project have been: * to design and implement a curvilinear mesh generator and associated graphics and utility programs for use with the numerical model of coupled heat and fluid flow; * to test the new mesh configurations by simulating the area around DSDP/ODP Site 504 in the eastern Pacific Ocean; * to conduct comprehensive parametric tests to determine the influence of physical variables (bathymetry, basement relief, permeability distribution, basal heat flow) on the extent, direction, and intensity of hydrothermal circulation; * to compile, review, and synthesize bathymetry, sediment thickness, and heat flow data from other sites where relationships between these variables can be elucidated; and * to complete simulations of other field areas and general settings to determine likely influences on off-axis hydrothermal activity in these settings.
