Summary of Field Work: |
We propose a 26-day site survey and coring cruise to 7 sites in the western equatorial Pacific in support of a pending and future IODP drilling proposals. The locations, compositon and accumulation rates of sediments in all these locations will provide new high-resolution records and very likely provide valuable insight into the role of the tropics in affecting and being influenced by global climate. We will utilize the R/V Thompson's capabilities (or any other available ship with built in compressor) to collect Simrad EM300 swathbathymetry and BATHY-2000 3.5 KHz sub-bottom profiles in locating coring sites. In addition, seismic reflection profiles will be collected with the Scripps portable seismic system to provide opportunities for later drilling. In keeping with the Guidelines of the IODP Site Survey Panel each target area will be surveyed with 48-channel 'high-resolution' MCS profiles. We will use a combination of multi, gravity and piston corers to collect sediment cores. Assuming that R/V Thompson is available, the cruise will depart from Guam and end up in Davao City, Philippines. |
Summary of Facility Requirements: |
We will require: (a) 3.5 kHz profiler; (b) swathbathymetry; (c) high-resolution MCS profiling; (d) coring to collect piston, giant gravity and muli-core samples; (e) shipboard MCS compressor; (f) 440 VAC 30 amp power for the MCS hydraulic pump. |
Summary of other requirements and comments: |
We request the hi-res MCS be provided by Scripps that in communication with Lee Ellett will comprise: (a) 600-m, 48-channel digital oil-filled streamer; (b) depth controlling 'birds'; (c) appropriate towing cables, deck leaders and winch for the streamer; (d) two GI airguns plus spares configured in 45/45 mode tethered to floats to control towing depth; (e) hydraulic power for MCS winches; (f) shot control system; (g) recording system; (h) monitoring/QC playback capability; and (i) two SIO personnel to oversee deployment, recovery and maintenance of the siesmic acquisition and recording system. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We need a ship with compressor available for the SIO HiRes MCS system and deck space for deploying the gear. We also need 3.5kHz profiling, swath bathymetry and coring capability for collecting piston, giant gravity and multicores. |

Short Description of Op Area
for use in schedules: |
Western Pacific |
Description of Op Area: |
Three sites are in low-sedimentation rate areas on the Carolina Ridge and Eauripik Rise (~8°N to 2°N ~142°E), which are covered by ~300 m of pelagic sediments. Two sites are on the northern and southern margins of Manus Island and contain well-layered, carbonate-rich hemipelagic sediments. The sixth site is near the Sepic River estuary of Papua New Guinea. We anticipate that good coring sites will be found in depositional areas protected from the strong coastal currents known in this region. This will require a longer survey time than at the other sites to find appropriate coring and potential drilling sites. |

Explain Instrumentation or Capability requirements that could affect choice of ship in scheduling. |
The SIO MCS system is transported in 2 20' containers; I don't know if they will be left at the port of departure or placed onboard the ship.
