Summary of Field Work: |
5 day cruise requested to deploy 10 ocean bottom seismometers offshore of Vancouver Island in summer of 2010 and a second 5 day cruise requested to recover them in summer of 2011 |
|
Summary of Facility Requirements: |
Hull transducer for acoustics, multibeam desireable, sufficient deck space for lab van and 10 OBSs. Science party will be relatively small <=10. |

Optimum Start Date:
|
6/1/2010 |
Dates to Avoid: |
Work is offshore of Vancouver Island Canada, so the weather window is roughly June-September. |

Repeating Cruise?
(within same year) |
Yes |
Interval: |
1 year |
# of Cruises: |
2 |
|
|
Description of Repeating cruise requirements: |
two cruises 1 year apart are requested; 1 in summer 2010, 1 in summer 2011; The objective of the first is to deploy 10 Ocean Bottom Seismometers, the objective of the second is to recover them. |
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
We are attempting to overlap our deployment with a experiment being conducted by JAMSTEC and NEPTUNE-Canada. To maximize overlap, we need the first cruise to be early in the 2010 weather window (June/July). |
