Okeanos Explorer (EX1504L3): CAPSTONE Leg III: Main Hawaiian Islands and Geologists Seamounts (ROV/Mapping)

The ship will conduct 24 hour operations consisting of daytime
ROV dives and evening/nighttime mapping operations including during transit.
During this cruise we will conduct 8 hour ROV dives on most days with occasional
10 or 12 hour dives (at the ship’s discretion) on particularly interesting or
deep dive sites. ROV operations will focus on depths between 350 and 3,000
meters and will include high-resolution visual surveys and limited sample
collection. Mapping operations will be conducted in 250 m of water and deeper,
and include overnight multibeam, water column backscatter, and sub-bottom data
collection. Opportunistic CTD rosette operations may be requested to collect
more information about the environmental parameters at ROV dives sites, or
opportunistically at selected sites where collecting the data is considered
important to understanding the physical or chemical properties of the overlying
water column.
