Temporal changes in venting at Brothers volcano, as indicated by backscatter and oxidation-reduction potential

Abstract

CTD-O, light backscatter and oxidation-reduction potential data were obtained for the hydrothermal plumes of the Brothers volcano. The data was compared to 2002 and 2007 datasets. Taken together, the data indicate that the plume is being advected in a westerly direction. Turbidity decreased significantly from 2002 to 2009. Other trends are discussed.
