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 4o 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 ho. 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.
