SHAWN ARNTD

MS  (in-progress)

Shawn began working with us during the summer of 2009 by participating in the research cruise of the German R/V Sonne in the western Aleutians and adjacent north Pacific and Bering Sea.  Shawn’s MS project is a geochemical study of lavas from Buldir Volcano, the westernmost emergent volcano in the Aleutian arc.  Buldir is interesting because it is both the westernmost and the most calc-alkaline of the emergent volcanos in the Aleutians.  The objective of Shawn’s thesis is to evaluate the genesis of Buldir lavas, in light of new results demonstrating the existence of isotopically distinctive source characteristics for nearby seafloor volcanoes in the western Aleutians. 

Shawn earned his BS degree in geology from Denison University in 2008.  He is pictured here doing field work in central Oregon in August, 2009.
