Cruise EW-0014 (Fremantle to Hobart, Australia) from Dec. 7, 2001 through Jan. 25, 2002. Acquisition of seismic refraction data using multi-element Ewing airgun array as a sound source and Ocean Bottom Hydrophones (OBH) as receivers. 6 deployments of 4 OBH each. Goal was to determine the dependence of melt supply on variations in mantle temperature at constant spreading rate & to invest. the effects of these variations on crustal accretion & the resulting crustal structure & morphology.
