Seismic Refraction Work by H.M.S. Challenger in the Deep Oceans
Abstract
An account is given of the seismic work carried out on the world cruise of H.M.S. Challenger. At most of the stations in the deep ocean a material giving a seismic velocity of 6\cdot 3 to 6\cdot 6 km/s was found covered by about 0\cdot 5 km of sediment. Some stations nearer the continents gave velocities resembling those found on land. Near volcanic islands 1\cdot 5 to 3 km of material giving a velocity of 4 to 5 km/s was found overlying material giving 6\cdot 5 to 7\cdot 0 km/s.
