Summary of Field Work: |
An active-source seismic experiment in the Aleutians to acquire MCS and OBS data along and across the Andreanof segment of the arc. One ship (Langseth) will shoot and acquire MCS data and also deploy and recover 37 OBS instruments for a total of 97 OBS drops. |
|
Summary of Facility Requirements: |
Multi-channel seismic ship with 15-km streamer and large-volume airgun array; 37 SP OBS instruments. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
R/V M.G.Langseth is required for seismic capability. May 1 start date is suggested to accomodate a separate cruise on Langseth already scheduled for June 2020. |
