Seismic East Pacific Rise 8°20'–10°10'N Endeavour Segment:Mid-Ocean Ridge Hydrothermal Magmatic Processes
2015/7/14
As part of the suite of multidisciplinary investigations undertaken by the Ridge 2000 Program, new multichannel seismic studies of crustal structure were conducted at the East Pacific Rise (EPR) 8°20'...
