Summary of Field Work: |
We propose to acquire multichannel seismic reflection data, marine and land seismic refraction data, and land and marine broadband seismic data in the Mid-Atlantic states (around Cape Hatteras) in May/July 2014. Broadband ocean-bottom seismometers (OBSs) will be deployed for one year, so they must be retrieved a year later in May/June 2015. |
|
Summary of Facility Requirements: |
We request the use of several vessels for this proposed project. Acquisition of marine seismic reflection and refraction data will be require 33 days at sea of the R/V Marcus Langseth in June/July 2014. We request the R/V Knorr to deploy a total of 30 broadband OBSs over 12 days in May 1-15, 2014. The R/V Knorr is also requested in May 2015 for 12 days to retrieved the broadband OBSs. We also request 26 days on the R/V Endeavor in June/July 2014 to deploy and recover 47 short-period OBSs. |
|
Summary of other requirements and comments: |
In our schedule, the R/V Marcus Langseth starts her 33-day ship cruise 1 day after the start of the 26-day cruise of the R/V Endeavor. The R/V Endeavor is the ship that we use for short-period OBS deployments. |

Optimum Start Date:
|
9/15/2014 |
Dates to Avoid: |
This request for ship time is linked to a request for the Marcus Langseth. We want to start in the early summer, but avoid hurricane season. |

Other Ship(s): |
This request for the Endeavor is linked to a request for the Marcus Length. The Endeavor will deploy short-period ocean-bottom seismometers that record seismic waves from the Marcus Langseth. |

|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We want to start the project at the start of the summer, which gives students an opportunity to help with data acquisition on-land and offshore. We do not want to start later in the summer because of the increased risk of hurricanes. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
In this project we use Earthscope FlexArray land seismic stations and OBSIP ocean-bottom seismometers. The WHOI IC of OBSIP will use a van for their operations.
