FOREWORD 



DEEP FREEZE 60 was the sixth consecutive United 

 States expedition in support of Antarctic research. 

 Personnel from the U. S. Navy Hydrographic Office, 

 supported by the National Science Foundation, con- 

 ducted marine geophysical research from several 

 icebreakers of TASK FORCE 43. In addition to oceano- 

 graphic studies in the Ross Sea, Amundsen-Bellings- 

 hausen Seas, and South Pacific Ocean, stations were 

 occupied along the Thurston Peninsula during the first 

 successful penetration into the previously unexplored 

 Bellingshausen Sea. The analyses and tabulation of 

 data collected are presented in this report.
