J. Journal of Geophysical Research, Volume 89, Issue B7, p. 6049-6069 We have used the Sea Beam multibeam echo-sounding system to survey the East Pacific Rise (EPR) from 18°20'N to 18°30'N, obtaining complete coverage of the EPR axial neovolcanic zone and all intervening transform faults. Here we focus on the EPR neovolcanic zone and the definition of overlapping spreading centers (OCS's) between the Orozco zone and Siqueiros transform faults. ...
