Summary of Field Work: |
This is a large active source experiment to seismically image the magma plumbing system of an arc volcano throughout the crust and into the upper mantle. We will record the RV Langseth 7,000 cuin air gun array on 93 SP OBS and 26 land stations with an aperture of up to 100 km for 3D tomographic imaging and with sufficiently high density for full waveform inversion. We will also leave 6 OBS around the Columbo seamount for one year to record seismicity for imagining magmatic and hydrothermal processes at this volcano and delineating its connection with the main Santorini edifice. |
|
Summary of Facility Requirements: |
Large, well-tuned air gun array; multi beam bathymetry |
|
Summary of other requirements and comments: |
93 SP OBS from OBSIP (WHOI and SIO groups) |

|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The RV Langseth is required to have a sufficiently large and well-tuned source for 3D tomography of the arc volcano throughout the entire crust and into the uppermost mantle as well as for full waveform inversion of the seismic data. We are also requesting 93 SP OBS from the OBSIP pool and so these would need to be available at the same time. The starting date is based on the projected Langseth availability and to avoid times of strong winds in the Aegean. The work could be successfully done in Sept or Oct of 2015 or May (perhaps June) of 2016. |

Explanation of Science Party Requirements and Technician Requirements |
I do not know how to give accurate estimates for these numbers. We will need:
Airgun source technicians of the RC Marcus Langseth
OBSIP groups from SIO and WHOI
MMO observers
Multibeam bathymetry collection - does this require a separate technician
There will also be the regular US science party (3 scientists & 3-5 grad students) as well as one Greek scientists and 2 of her graduate students. |
