IX. ACKNOWLEDGMENTS 



The work reported upon in this paper was made possible by a grant from 

 the National Science Foundation through the U. S. Antarctic Research Pro- 

 gram. The authors wish to acknowledge with thanks the invaluable assist- 

 ance rendered by the U. S. Navy at NAF McMurdo. The Commanding Officer, 

 CDR Lloyd W. Bertoglio and his Executive Officer LCDR Burtis W. Warren, 

 were extremely cooperative, as were all the Navy personnel at the base. 

 Thanks are also due Mr. Stoner B. Haven, technician in charge of the 

 Stanford University Biological Laboratory at NAF McMurdo, who on numerous 

 occasions assisted the authors at the icehole and in the laboratory. His 

 replacement, during the second summer, Mr. Karl E. Ricker, also gave much 

 helpful assistance. Mr. Jack L. Littlepage of Stanford University had 

 volunteered to complete the year's series of oceanographic stations after 

 the authors had departed McMurdo but, after taking one station in early 

 March 1961, loss of the icehole hut prevented his continuing with the 

 program.
