Summary of Field Work: |
This cruise will recover 6 intermediate period ocean bottom seismographs. The OBS are recording ambient seismic noise and the data will be used to characterize physical properties of slope sediments. If time allows, we will also test various marine geophysical instruments. |
|
Summary of Facility Requirements: |
back deck, A-Frame or ship's crane for OBS recoveries, hull-mounted Knudsen CHIRP, acoustic communications, dry lab space |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Sharp is an ideal platform for the OBS recovery, and, barring a hurricane, can handle weather typical of the North Atlantic in August-September. Sharp will also be in Woods Hole for NOAA and ONR work and has schedule availability. |
