The refrigeration system of the 

 Arctic Maid consists of six 6,000-gal- 

 lon brine tanks, four 8, 000-gallon brine 

 tanks, and a 600-ton-capacity hold, 

 cooled by absorption type coils. Cooling 

 plants are two ammonia compressors 

 each capable of delivering 70 tons of 

 refrigeration. (One ton of refrigeration 

 is defined as cooling necessary to con- 

 vert 1 tonof water at 32° F. into 1 ton of 

 ice at 32° F. per 24 hours.) 



The processing area was located 

 forward on the brine tank deck and was 

 equipped with a boning table, a 15-hp. 

 meat grinder with 3/4-inch cutting 

 plates, a conveyor worm, and a metal 

 hopper from which meat was sacked. 



The ship carried two 31 -foot 

 Bristol Bay-type gill net boats which 

 were" used to shuttle hunting parties 

 to the beach and to transport dead 

 animals. They were also used to pull 

 dead animals from the beach into the 

 water. 



Members of the working crew, 

 which numbered 10 men including the 

 captain, not only worked the ship but 

 also served as hunters or butchers. The 

 cook and 3 engineers brought the ship's 

 complement to 14. 



Hunting and Retrieving 



The Arctic Maid took sea lions 

 from five of the many rookeries in 

 waters of the North Pacific Ocean 

 between Kodiak Island and Unimak Pass 

 (fig. 3). The first rookery visited was 

 Marmot Island, northeast of Kodiak 

 Island, where 2 weeks were spent in 

 developing hunting and processing tech- 

 niques. The methods evolved at Marmot 

 Island were employed during the re- 

 mainder of the season. None of the 

 crew had previous experience in meat 

 processing. At first they made them- 

 selves available as the work dictated, 

 but soon each man had a specific job.
