The data for this report were collected by Robert S. Dietz, of the Oceanography- 

 Section of the U. S. Navy Electronics Laboratory, with the assistance of 

 Herbert J. Mann, of the Scripps Institution of Oceanography, both of whom, as Navy 

 Electronics Laboratory representatives, accompanied ships of the Western Task Group 

 of Task Force 68 ori Operation HIGHJUMP. Personnel of the USS HENDERSON and the 

 USS CACOPAN furnished assistance in the collection of the oceanographic data. 



The report was prepared by R. S. Dietz with assistance from and supervision by 

 E. C. LaFond and with assistance from D. W. Pritchard. The work of Luis Capurro, 

 who made a study of the heat content and temperature distribution in antarctic water, 

 and the work of Estil Hamill, who investigated internal waves, are adapted for and 

 included in this report. 



The bathythermograph records were processed by the Bathythermograph Pro- 

 cessing Section at the Scripps Institution of Oceanography. Salinity determinations 

 and the analysis of a lake water sample from Antarctica were made under the 

 direction of N. M. Rakestraw of Scripps Institution of Oceanography. D. M. Updegraff 

 and Brian Boden of the same Institution furnished, respectively, bacteriological 

 analyses of sea floor sediments and information on the antarctic phytoplankton.
