Summary of Field Work: |
The goal of this project is to determine crustal structure along and across the Hawaii and Emperor seamount chains using a series of 2D seismic reflection/refraction profiles. We envisage that the work would take place during two parts. The first part would involve an experiment from Honolulu-Honolulu using the Langseth. The second part would involve an experiment aboard the Langseth from Honolulu to Adak, Alaska. We chose these ports based on the Langseth regional plan, but could use different ports as needed. OBS deployments and recoveries as well as acquisition of seismic reflection/refraction data would all take place from the Langseth. |
|
Summary of Facility Requirements: |
We require the large, tuned air gun array and long streamer of the Langseth for acquiring seismic refleciton and refraction data along our profiles. We will also be deploying and recovering OBS, and will need space for prepping and storing them and a suitable crane for deployment/recovery. |

Explanation/justification for requested
ports and dates of intermediate stops
or to list additional port stops |
The field area is quite remote. Several other ports would be possible for beginning/ending the cruise, particularly Tokyo. We chose these particular start and end ports based our understanding of the Langseth's regional plan. |

This cruise would be collaborative with GEOMAR in Germany, who would provide some OBS for the proposed work. So, we would also need to coordinate with their OBS group for this program. |
