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 |

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 of day, preferably while the CPIES are still on the sea floor. |

Explain Instrumentation or Capability requirements that could affect choice of ship in scheduling. |
A CTD winch, shipboard CTD with back-up sensors are requested for hydrographic sampling.
Launch operations for CPIES require a stern A-frame with air-tugger or capstan or small winch for lifting about 240 lbs. Recovery operations require the portside crane.

|
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 frequency 2) A 12 kHz in-hull transducer for acoustic commands and receiving an acoustic beacon from the CPIES. 3) An RDF on the bridge for CPIES relocation. The CPIES relocation radio is standardly 156.875 MHz “CHANNEL 77” marine band. |
