Summary of Field Work: |
We will conduct a 42-days cruise (includes 10 days transit) to collect high-resolution near-bottom magnetic data in the Hawaiian Jurassic crust (in the central western Pacific).
We will use the AUV-Sentry operated by National Deep Submergence Facility and MISO-TowCam to collect two 800 km sub-parallel magnetic survey lines.
While the battery charge of the AUV-Sentry (~16 hours), we will shoot seismic along the magnetic survey lines to collect both reflection and refraction data. We will use SIO high-res portable seismic system for the reflection data collection, and use sonobuoys for the refraction data collection.
During underway and MCS operations, We will collect multibeam, 3.5 KHz chirp, and gravity concurrently.
During the AUV operation, we will also shoot seismic with long shot intervals for sonobuoys. |

Summary of Facility Requirements: |
NDSF Sentry-AUV
MISO-TowCam
Scripps high-res portable seismic
Built-in compressor for the GI guns (so, this automatically requires either Revell or Melville)
Scripps shipboard geophysics surface magnetometer and gravitymeter
Shipboard 3.5 KHz and Multibeam system |

Requested Start Port |
Intermediate Port(s) |
Requested End Port |
|
Honolulu, HI, USA |
None |
Apra Harbor, Guam |
Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
We request the start port Hawaii because we will tow a surface magnetometer along previously collected magnetic profiles from off-Hawaii to our survey area in the central western Pacific. This is necessary to locate us precisely at the end of those previous survey profile. We request end port Guam because that would be the closest port from the predicted location pf the end of our survey line. |
