Summary of Field Work: |
This project is to do seismic reflection/swath mapping of proposed IODP drill sites in the North Atlantic, from 33 to 52 degrees N. We plan to use the Scripps high-resolution seismic reflection sources and streamers and will not only survey specific sites (2-3 days each) but will also do seismic reflection profiles between sites. |
|
Summary of Facility Requirements: |
Scripps high-resolution seismic reflection acquisition system and streamer
Multibeam swathmapping
digital subbottom profiling |

Description of Repeating cruise requirements: |
none |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The cruise will be to do a seismic survey in the North Atlantic for IODP, with ties to existing DSDP drill sites. We request days in summer to avoid significant bad weather. We need a ship with multibeam, digital subbottom profiler, and room for the Scripps high-resolution seismic reflection system. |
