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. |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We request the Marcus Langseth for an onshore-offshore active-source seismic experiment. The project involves many students in data acquisition on-land and offshore. To accommodate their university schedule, we prefer to start the marine seismic cruise no earlier than May. Later in the summer the chance of a hurricane encounter is larger, so we prefer to start the ship cruise before the end of May. |

Explain Instrumentation or Capability
requirements that could affect choice
of ship in scheduling. |
This project uses OBSIP ocean-bottom seismometers that will be deployed from another ship (not the Marcus Langseth). The seismic waves will also be recorded on-land by land-seismic stations from the Earthscope FlexArray.

and provider for "other" systems. |
We will use both the air-gun array and 8-km seismic streamer for 2-D seismic lines. |
