Summary of Field Work: |
After commuting to site N, two miniHARP moorings will be recovered by hand. If time permits, the remaining two seafloor instruments will be localized by driving circles around the instrument locations while continuously pinging to them. After that, the two seafloor instruments (4chHARPs) will be recovered with the A-frame. If time permits, a full CTD cast will be performed on the site. If not, a couple of XBTs to obtain the sound velocity profiles will be conducted at that site. Once all that work has accomplished at site N, we will deploy an acoustic array with the winch and tow it behind the ship while simultaneously conduction marine mammal observations on the way back to MARFAC, San Diego. |

|
Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
-ship with A-frame required to recover seafloor instruments(4chHARPs)
-batteries of seafloor instruments need to be working at the time of recovery=>probability of working batteries decreases dramatically after 02/16/2011 |
