The much-appreciated, excellent cooperation continues to be extended
by officers and men of the Granville S. Hall. Fine cooperation was also
received from the officers and crews of the LT's.
The departure of the YAG 40 from Long Beach was delayed due to a
breakdown in after-steering. The LT's were used for the first third of
the Grid survey to prevent disruption of the fall schedule. Seas were
small during this first period, providing good observing conditions from
the tugs. En route to the Grid the LT made an offshore survey of the
south sides of Anacapa, Santa Cruz, and Santa Rosa islands.
During the in-port period in Long Beach a Bathythermograph winch was
acquired and installed on the YAG 40. The winch was most generously loaned")to us by Scripps Institution of Oceanography for the duration of the work.
Methods
Complete diurnal observations were taken while in the Grid area.
Nocturnal observations were taken 29 August through 3 September, both
while underway and while laying to. During the 2-1/2 hours of laying-
to on 31 August a floating mist net was successfully launched from the
ship. During this same period the boat launching platform was lowered
and unsuccessful attempts were made to collect cephalopods.
The skiff was used 2 and 3 September for collecting birds while in
the southern portion of the Grid. Attempts were made to collect specimens
of Delphinus from the skiff as well as from the ship.
