Summary of Field Work: |
Deploy and recovery an array of twenty-five bottom-mounted CPIES (current pressure recording inverted echo sounders) in the central Gulf of Mexico. The array is centered near 26.1N, 87.26W.
Measurement duration is ~18 months with capability of 36 months. Project will also include a telemetry cruise approximately 6 months after CPIES deployment. Full-water column
CTDs will be taken at each site on each cruise. Water depths in array range from 2400 to 3400 m. |
|
Summary of Facility Requirements: |
Launch operations for CPIES require a stern A-frame with air-tugger or capstan
or small winch for lifting about 240 lbs.
CPIES telemetry cruise will require a 12 kHz in hull transducer for acoustic signaling and
telemetry reception.
Recovery operations occur along the forward starboard rail, assisted by a davit
and either block-and-tackle or air-tugger, to lift pieces of about 80 lbs.
A CTD winch, shipboard CTD with back-up sensors are requested for hydrographic sampling.
A shipboard ADCP with frequency of 150Hz or lower is highly desirable. |
|
Summary of other requirements and comments: |
We would like to use a 12 kHz in hull transducer for acoustic signaling and
telemetry reception. This is essential for the telemetry cruise.
The CPIES relocation radio is standardly 156.875 MHz
"CHANNEL 77" marine band. A Taiyo RDF on the bridge (or an
updated equivalent) is helpful for CPIES recovery |

 Important Info on Foreign Research Clearances
|
|
Are you or any member in your science party bringing in any science equipment items which are regulated for export by the International Traffic in Arms Regulations (ITAR) and/or the Export Administration Regulations (EAR)?
|
Yes |
If yes, have you applied for the necessary permits through your export control office?
|
Yes |
| Questions about ITAR/EAR regulations?
|
Comments about foreign clearance requirements or
description of any other special permitting requirements
(e.g., MMPA, ESA, IHA, Marine Sanctuaries, etc.) |
Some of our deck gear and moored instruments have Export control ECCN numbers, but no ITAR gear is involved. |

Explanation of Science Party Requirements and Technician Requirements |
We request the ship operator to supply two CTD technicians, so that the deep CTDs can occur at any time after the CPIES are on the sea floor. |

Explain Major Ancillary Facilities
Requirements and list description
and provider for "other" systems. |
The following equipment is highly desired but not essential:
1) ADCP of 150kHz or lower
2) A 12 kHz in-hull transducer for acoustic commands and receiving
an acoustic beacon from the CPIES.
3) A Taiyo RDF for CPIES work. The CPIES relocation radio is standardly 156.875
MHz “CHANNEL 77” marine band. |
