Abstract :
Preliminary results are presented from an expedition to the ultra-fast spreading segment on the East Pacific Rise. The combined multibeam and sidescan sonar worked extremely well, and provided the authors with surprising discoveries of abundant off-axis volcanism. Individuals from several institutions have contributed to a collection of public domain software for processing and displaying SeaBeam 2000 data, much of which is being used to visualize the East Pacific Rise
