APPENDIX 



Bathythermograph lower ings made by the Fisheries Research Institute, 



University of Washington 



The biologists aboard the MV's CALIFORNIA ROSE, COMMANDER, and 

 RENCWN made bathythermogrjqjh lowerings throughout the season to sup- 

 plement the data collected along the Aleutian Chain by the vessels 

 chartered by Pacific Salmon Investigations. The observations were 

 restricted generally to the fish tiigging areas. 



These observations vary somewhat from those teiken in conjunction 

 with gillnetting. Wind direction is recorded almost silways to the 

 nearest two points of the compass. Wet bulb thermometers were not 

 observed. In the COMMANDER'S data, the bsirometer was recorded in 

 inches graded to tenths, and the columns of barometer, weather, clouds, 

 visibility, sea and swell have been converted to the HO 606-C code.
