Ship Request

STR Management has moved to MFP

The US Academic Research Fleet is moving to Marine Facilities Planning (MFP) for scheduling initially and eventually cruise planning.

For all NEW or RESUBMITTED Projects/Ship Time Requests, go to and create a new SME. Some STRs for projects starting in 2022 and beyond have already been moved to Marine Facilities Planning ( Check your MFP Science Portal for any projects that might already be moved. If you need to make edits to projects that begin in 2022 and beyond, please contact for assistance. Be sure to indicate the Project and STR IDs that you would like to edit. For more information on getting into MFP, see the More Information button below.

  Project Information  
Project Title: Collaborative research: Crustal magma plumbing of the Santorini volcanic system Project Status: Submitted
Principal Investigator: Emilie Hooft, UO Project Institution: UO
Project ID: 104482 Version #: 1
Date Submitted: 8/7/2014 1:01:00 PM Created By: Emilie Hooft
Date Last Modified: 1/12/2015 9:55:00 AM URI Serial #: None
Funding Agencies: NSF/OCE/MGG - 1459794 - Funded
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)

Requested Ship, Operating Days and Dates
Year: 2015 Ship/Facility: Marcus Langseth
Optimum Start Date: 9/1/2015 Dates to Avoid: other than winter the worst weather in the Aegean is during the summer meltemi (strong north winds) in July and August
Earliest Start Date: 5/1/2015 Multi-Ship Op: No

Repeating Cruise?
(within same year)
No Interval:   # of Cruises:  

Description of Repeating cruise requirements:
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.

Science Party
Chief Scientist: Emilie Hooft, UO
# in Science Party 24 # of different science teams 5 # Marine Technicians to be
provided by ship operator:
(include in science party total)
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.
