A Map Series of the Southern East Pacific Rise and It's Flanks, 15° S to 19° S

Abstract

Four large-scale bathymetric maps of the Southern East Pacific Rise and its flanks between 15 S and 19 S display many of the unique features of this superfast spreading environment, including abundant seamounts (the Rano Rahi Field), axial discontinuities, discontinuity migration, and abyssal hill variation. Along with a summary of the regional geology, these maps will provide a valuable reference for other sea-going programs on- and off-axis in this area, include the Mantle ELectromagnetic and Tomography (MELT) experiment.
