Summary of Field Work: |
Collect 60 broadband marine magnetotelluric recordings in a grid offshore Oregon as part of a collaborative onshore/offshore study to examine the role of fluid distribution in episodic tremor and slip and seismic hazard. |
|
Summary of Facility Requirements: |
Intermediate class research vessel out of Oregon (preferred) or Washington. Requires a deployment cruise and then a recovery cruise 4-6 weeks later. Summer cruise preferred to keep wave noise down on shallow water deployments on continental shelf. |

|
Ship/Facility: |
Oceanus
|
|
Optimum Start Date:
|
7/1/2014 |
Dates to Avoid: |
Prefer summer months for weather since large winter sea swell causes noise on ocean bottom EM sensors deployed on continental shelf. |

Repeating Cruise?
(within same year) |
Yes |
Interval: |
4-6 weeks |
# of Cruises: |
2 |
|
|
Description of Repeating cruise requirements: |
A deployment cruise of 7 days to deploy 60 seafloor EM sensors. They need to record for 4-6 weeks. Then a recovery cruise of 12 days to pick them all up. We only need 1 mob and 1 demob days per cruise (so 4 in total). |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Given the need to host 60 seafloor instruments and 60 concrete anchors on the deployment leg, an intermediate class vessel such at the Oceanus or New Horizon (or larger) may be suitable in summer. |
