Median Valley Refraction Line, Mid-Atlantic Ridge at 37° N

THIS communication describes the results of a reversed seismic refraction line carried out with explosives and seabed receivers in the median valley of the Mid-Atlantic Ridge during July and August 1973. The work was part of a detailed investigation of a crestal area of the Mid-Atlantic Ridge south-west of the Azores by the Franco-American Mid-Ocean Undersea Study (FAMOUS) group.
