|
Summary of Field Work: |
We will use the R/V Langseth to deploy and recover 23 OBS in two deployments, use the airguns on the Langseth to shoot two seismic refraction lines, and then use the 12 km streamer to collect 1,730 km of MCS lines. |
|
Summary of Facility Requirements: |
R/V Langseth, its airgun and the 12 km streamer. We will use the multi-beam capability, gravimeter and magnetometer. |
|
Summary of other requirements and comments: |
We will bring with us 23 OBS from UTIG |

Dates to Avoid: |
Avoid austral winter season (April September) due to likely bad weather - rough seas will degrade the quality of the data and make operations more difficult |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The R/V Langseth is required because of its unique seismic capabilities.
The dates are chosen to conform to Austral Summer and the NSF Regional Seismic Plan |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
Seismic operations will include using 6600 cu in airguns and MCS with 12 km streamer and XBTs during seismic acquisition. Multibeam, sub-bottom profiler and gravity while underway.
When the streamer is not deployed, we will deploy the Geometrics 882 Magnetometer.
