Summary of Field Work: |
Recovery of four seafloor pressure recording packages deployed in March 2010 as part of the Chilean Earthquake rupture survey. Units were configured to sample ambient seawater pressure once per minute continuously over the past year. They will be commanded to drop a weight via an acoustic command sent from the surface ship. At each of the four sites the density structure from sea surface to seafloor will be measured by profiling a conductivity, temperature, and pressure device (CTD). |

Description of Repeating cruise requirements: |
|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
Depature at 1600 local on day 1 permits loading of gear and science party on day 1, thus no Mob day request. Likewise arrival at 0800 on day 6 permits offloading of gear and sciene party on day 6, thus no Demob day requested. This gives 4 and 2/3 days at sea. First site is within 10 hours transit thus no transit day requested. |
