Collaborative Research: Interdisciplinary Approach To Understand Stable Isotopic disequilibrium in Benthic Foraminifera
Goals and Objectives
 
An extensive geochemical and biogeochemical examination of methane seeps in the Clam Flats area of Monterey Bay provides insight into the character of relationships between seep geochemistry and benthic foraminiferal geochemistry. The geochemistry of the pore fluids should be relevant to the geochemistry of the carbonate tests of living and dead foraminifera. In one study, a recently developed method was used to compare stable carbon isotope ratios of foraminiferal carbonate with cell ultrastructural observations from individual benthic foraminifera from seep (under chemosynthetic bivalves) and nonseep habitats in Monterey Bay, California, to better understand control(s) of benthic foraminiferal carbon isotope ratios.
