Summary of Field Work: |
This proposal will develop a new autonomous water column biogeochemical sampling vehicle, Clio, that can be used simultaneously and independently of traditional wire based sampling systems employed on research vessels. Clio will be a 6000 m rated vertical autonomous underwater vehicle (AUV) with a high throughput sampling and sensing payload that will conducted 14 hr dives.
The vehicle will be deployed with an A-frame, J-frame, or crane using a manually operated quick-release. Operators will track the vehicle during its dive using an acoustic ranging system and receive regular vehicle status information with integrated acoustic telemetry. The vehicle will alert operators to its arrival back on the surface using three independently-powered depth-activated beacons: a GPS/Iridium unit to provide over-the-horizon location, a strobe for line-of-sight location, and a VHF radio beacon. Our recovery procedure is modeled after other mid-size AUV systems. To recover the vehicle operators will first snag a lifting bale on top of the vehicle using a light-weight lifting line secured with breakaways to a tagline pole, partially lift the vehicle out of the water, attach additional taglines, and finally bring the vehicle aboard. We expect recovery times totaling ~1hr.
In year 3 of this proposal (2015/2016), this vehicle will require 5 days of sea trials in deep water (4500m to 6000m) which is the subject of this request. As this is an instrumentation development project, a wide range of ships and operating areas could meet our needs. The essential requirement is being able to reach an operational area with 4500 to 6000 m of water depth. We expect the work could be accomplished during a UNOLS vessel transit between major expeditions on the east or west coast and budgeted for shipping costs to as far as Hawaii. Hawaii is of special interest due to related biogeochemical work by co-PI Saito in this area.
Our plan of work includes validating all vehicle operations to full design depth, we are planning for 4-5 vehicle deployments of varying lengths up to 14 hrs. During each deployment the ship must hold station. The ship can proceed along a transit between dives while the vehicle is being serviced. |
|
Summary of Facility Requirements: |
The main requirements are (1) a vessel with an A-frame, J-frame, or crane rated to at least 4600 lbs to deploy and recover the vehicle, and (2) the berthing capacity to accomodate our 5 person science and engineering team of men and women. |

|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Ship choice and operation area are flexible, we can make use of a large number of vessels in a deep water operating area (4500-6000m) as long as they meet our minimum lifting capabilities for vehicle launch and recovery and our berthing requirements. As this purpose is to perform sea trials of a new AUV, an operating area and time frame where we can have the best chance for relatively calm weather and seas - of the nature required for ROVs and AUVs such as Jason and Sentry would be the best fit for our needs. |
|
Short Description of Op Area
for use in schedules: |
6000 m depth |
| Description of Op Area: |
We need an operating area where water depth is between 4500 m to 6000 m. Each vehicle deployment will require clear vessel maneuvering space within a 6 km radius of the dive location to ensure vehicle recovery. This vehicle will drift with ocean currents during its deployment.
As this purpose is to perform sea trials of a new AUV, an operating area and time window where we can have the best chance for relatively calm weather and seas - of the nature required for ROVs and AUVs such as Jason and Sentry would be the best fit for our needs. |

Explanation of Science Party Requirements and Technician Requirements |
We have a 5 person team to launch and recovery our vehicle. A ships science technician will be needed to assist in these operations and for supporting CTD launch and recovery to collect background water column profiles. |
