| Abstract |
Award is for a project to conduct a series of flux meter measurements
along transects across hydrological boundaries in the down going
plate off Costa Rica. This region is characterized by anomalously
low heat flow, except over regions of topographic highs that exhibit
anomalously high heat flow values. The flux meter measurements will
test the hypothesis that the regions of low heat flow are characterized
by downward fluid flow, while the high-heat-flow areas are characterized
by upward fluid flow. A second portion of the project will be to
return the areas on the accretionary prism where 35 flux meters
were deployed as part of a previous study, to collect piston cores
and heat flow measurements. Analyses of these cores will result
in co-located temperature, chemical gradient, and direct fluid flux
data sets that will provide a more complete hydrological picture
of the incoming plate and the Costa Rica forearc. |
