Science Objectives
This is the annual maintenance cruise for NSF's Ocean Observatories Initiative Regional Cabled Array. The main objective is to complete all required turns (recovery and reinstallation) of infrastructure and to complete add-on PI work funded by NSF, ONR, and the German government.  The cruise will require four legs (see attachment), Newport-Newport working in 5 main locations - Oregon Shelf (80 m water depth); Oregon Offshore (600 m); Slope Base (2900 m); Axial Base (2700 m); and Axial Summit (1500 m). A detailed cruise plan for each leg wil be provided including individual dive summaries, maps etc.
Science Activities
The objectives include recovering and replacing a two-legged shallow profiler mooring at the Axial Base site (~22 hr steam from Newport Oregon), turning (recoverying and reinstalling) of three Deep Profiler vehicles on moorings; turning numerous secondary junction boxes, and ~100 instruments. The cruise will include 4 legs  Newport - Newport. In addition to the Cabled Array work, we will also be installing: 1) an NSF-funded PI geophysical instrument (AOA: W. Wilcock-UW) at the summit of Axial Seamount; 2) recovering and perhaps reinstalling a multibeam sonar (COVIS: K. Bemis Rutgers University) in the ASHES hydrothermal field on Axial; 3) recovering and reinstalling a multibeam sonar (OVERVIEW: Y. Marcon  and G. Bohrmann, MARUM - Bremen University), as well as a 4K camera at Southern Hydrate Ridge; 4) recoverying an uncalbed instrument from the OR Offshore site (C. Reimers - ONR) and perhaps installing another uncabled instrument at Southern Hydrate Ridge); and 5) installing a cabled camera system and uncabled platform in the ASHES hydrothermal field (HTEV: J. Breedlove-ONR). We will also conduct multiple CTD sampling casts for follow-on analyses for instrument verification, limited sampling of gases usign IGT bottles, and sampling of sediments with push cores. Attached files that will be helpful include: overview image,  high level summary of the schedule for each leg (arrive-depart-mobe/demobe), draft deck layouts, and high level summary of locations for major infrastructure at each of the sites.

Additional Information

Is night time work anticipated on this cruise?yesSpecialized tech support (Seabeam, coring, other):
Operations will run 24/7..anticipate >40 Jason dives.Other required equipment and special needs:
We will need emhanced bandwidth re HiSeasNet and 4 VOIP phones - UW Ken Feldman will aide in this. Will need unrestricted file size access/daily quota for several members of the RCA UW team.

Will need the work boat for Leg 1 during the Shallow Profiler Mooring work, but not on Legs 2-4, so can be stored following Leg 1.

Although we dont need maps made of the work areas, we will use the EM122 system to image methane bubble plumes.
