Gretchen Früh-Green (a.k.a. Gretchen Bernasconi-Green) is a senior research scientist in the Department of Earth Sciences at the ETH-Zurich, Switzerland. Her research involves studies of the alteration of the oceanic crust and she is particularly interested in the geological, geochemical and biological consequences of serpentinization - a process involving the interaction of seawater with mantle rocks.
She will be participating as a petrologist and stable isotope geochemist on this cruise and will be working with the other members of the science team to understand how seawater circulation and the alteration of the basement rocks control the hydrothermal activity at Lost City. Her research group at the ETH-Zurich currently includes two graduate students and two undergraduates.
