During the VISIONS'13 Expedition, three subnets were completed at this site (highlighted in blue). They include: 1) a medium-powered J-box MJ03B in the ASHES hydrothermal field, which is connected to two short-period seismometers; 2) an HD camera also in the ASHES hydrothermal field; and 3) a medium powered J-box MJ03E connected to two short-period seismometers. Over 20 km of extension cables, with lengths up to ~ 5 km, were successfully installed in 2013 using the ROV ROPOS. All extension cables and subnets were fully tested and are functional, awaiting to be connected to Primary Node PN3B. The remaining infrastructure will be deployed in during VISIONS'14, next year.

Each year, the summit of the ~ 16 m tall chimney 'El Guapo' (the handsome one) is visited. Fluids venting at ~350° are on the boiling curve and are reminiscent of flames in the deep sea. Credit: UW/NSF-OOI/WHOI V20
