Subject: Plan for 30 Oct Sproul trip
Cc: shipsked@ucsd.ucsd.edu

Louie, and Tam; Here is a work plan for my next Sproul cruise.

Wednesday 30 Oct  Evening:   Depart so as to arrive off Red Beach at daylight or
                             so the next morning.

Thursday, 31 Oct  Begin deployment of OBSs.  The array will be about 50 meters
                  across, and the near-shore end will be in about 10 meters of
                  water (at low tide).   There are 13 instruments to deploy
                  so we will probably not finish before dark.
                 
                  Evening:  run some bathymetric survey lines

Friday,   1 Nov   Complete deployment of OBSs.  Acoustically survey array.
                  When this is done, depart for deep-water cangun test.

                  This will consist of up to about three lowerings of a
                  metal cylinder can with a ceramic plate on the end.
                  Depending on the result of the first test, we may
                  want to try to use a glass-breaker on one of the
                  later tests.

                  This requires 700 or 800 meters of water depth, so we need
                  to be in the San Diego Trough (location not critical).
                  Since we do not have to steam, we ask to do this on
                  an op-area boundary.

                  If deployment of OBSs takes longer than planned, I
                  would like to do this on Saturday morning just before
                  we go in, so an area close to San Diego would be the
                  most convenient.

                  Louie, do you have a "favorite location" for this?

Saturday 2 Nov  Return to port.
