Fig. 7From: Active-source seismic survey on the northeastern Hawaiian Arch: insights into crustal structure and mantle reflectorsObserved arrivals and calculated travel times for all OBSs. Vertical bars indicate the uncertainty of the observed arrivals. Reduction velocity is 8.5 and 8.0 km/s along the EW line and the NS lines, respectively. The colors of the calculated travel time curves are explained in Fig. 6Back to article page
