Soon to leave Newport -ROPOS to start diving at 9000 ft this afternoon - installing a deep profiler mooring.
ROPOS to dive at methane seep later tonight hosting Neptunea snail nursery interactiveoceans.washington…
now diving at >9000 ft at base of volcano.
5 ft long rattail at 5000 ft on Axial Volcano.
ROPOS is diving in the International Field at 5000 ft working at the 280°C hydrothermal vents on the largest volcano off the OR coast

The R/V Thompson and remotely operated vehicle ROPOS are on their way to the largest underwater volcano off the Oregon Coast-arrive tomorrow
ROPOS starting its descent to 2900 m off the Oregon Coast at the Base of the Canadian Subduction Zone
ROPOS Dive R1827 starting - ROPOS in the water
NSF Cabled Array OOI cruise underway - steaming to Slope Base - arriving at ~2200 tonight to switch our mooring science pods
2-leg vertical mooring at SlopeBase is safely in position after 21hr deployment complicated by strong currents and winds >20kts #visions14
Back at Sea! En route to Slope Base to deploy a 2 Legged Mooring in 2900m of water. Mooring ops start Friday 0600 hrs #Visions14
