Survey Ship: USS REXBURG, PCER 855 
Methods: 
Diurnal observations were maintained from the forecastle and the open 
bridge as weather dictated. Bathytheromograph casts were made at four hour 
intervals, buG were discontinued for 12 hours on the 17 th due to heavy seas. 
Bucket temperatures were taken until it was found that they agreed exactly 
with the B-T instrument. However, the sea water injection temperature 
(recorded on the weather)log never agreed with bucket temperature. The skiff 
was not put in the water due to heavy seas. 
The REXBURG carried three rubber fuel cells containing ca>7500 gallons 
of diesel fuel.on her decks. Before the last of these could be emptied the 
cell broke up emptying more than 2000 gallons of fuel over the decks and 
into the sea. 
The PCer class ships are well suited to the survey needs. 
Conditions: 
Snow in San Diego on the day of departure heralded conditions through¬ 
out the survey. Temperatures averaged below normal the first three days. 
Winds were high and the seas higher than normal. Only on the last two days 
of the survey while on the last leg did conditions moderate and seas go 
down.
