Summary of Field Work: |
This proposal presents a plan to conduct a 6-month Southern Ocean experiment near Drake Passage using a Liquid Robotics Wave Glider SV3 autonomous surface vehicle deployed during an OOI Southern Ocean buoy turnaround at 55S,90W and recovered from the R/V Laurence M. Gould in the weak-current region between the Polar Front and the Southern ACC Front in Drake Passage.
The vehicle will carry instrumentation to measure winds, surface waves, and upper-ocean velocity structure. This effort will advance our understanding of Southern Ocean air-sea coupling while developing a new capability for the autonomous collection of Southern Ocean survey and timeseries data. |
|
Summary of Facility Requirements: |
Three berths on each cruise are requested for scientists from APL-UW to set up and deploy/recover the Wave Glider on 2 cruises (deployment and recovery) separated by about 6 months. Only about an hour of ship time will be needed for the deployments (to stop the ship, heave to, and launch the vehicle--probably by lowering with a crane) depending on conditions. Recovery time may take up to 2 hours from the time the vehicle is sighted, though probably less. Assistance from 1 or 2 crew or science party members may be needed. |
|
Summary of other requirements and comments: |
Some planning for (or at least discussion of) flexibility is requested in advance. The Wave Glider will be operating in a challenging environment, so there is a chance that an early recovery will be needed (either during the deployment cruise or, for example, 4-5 months after deployment, rather than 6). Deployment cruise flexibility will require launching the Wave Glider before other work at the OOI buoy so that performance and data quality can be evaluated prior to leaving the site.
Recovery cruise flexibility requires the consideration of contingency recovery opportunities on other Drake Passage cruises during the 2016-17 field season. We understand that substantial extensions of the deployment cruise or deviations from the Gould's planned track or schedule for recovery are unlikely to be possible, but we also expect that switching a minimum-impact recovery operation to a different crossing can be accommodated with sufficient advance warning. |

This is the first cruise on the project and will be coordinated with the WHOI CGSN (Coastal and Global Scale Nodes) group. Almost any time in austral spring 2016 is acceptable, provided that the recovery cruise can take place approximately 6 months later. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
1 funded science day is requested to ensure adequate time to deploy a Wave Glider SV3 autonomous surface vehicle at approximately 55 S, 90 W during the OOI Southern Ocean turnaround cruise. Ideally, the deployment will occur immediately upon arriving at the OOI buoy site so that initial vehicle performance can be evaluated and a recovery made if necessary. Most Wave Glider failures occur because of problems on deployment, so a recovery contingency plan is needed. |

requirements that could affect choice
of ship in scheduling. |
Depending on the ship selected for the OOI turnaround (i.e., either a global class vessel or the Nathanial B. Palmer), the Wave Glider deployment will likely be with a crane on the starboard quarter. Adequate deck space is needed to stage the Wave Glider SV3 and swing the crane. Space will also be needed for the Wave Glider SV3 shipping box.
