equipment, as used aboard ship, was such that the results were considered question- 

 able; these data are not included in this report. 



5. Magnetic Total Intensity 



A nuclear resonance total intensity magnetometer, with the sensing unit 

 towed 500 feet astern, was used to record total intensity. Data measurements were 

 recorded once every 2 seconds of time on a strip-chart recorder. Total intensity 

 data records were scaled and converted to values in gammas (1 gamma equals 10"-* 

 oersted) . 



D . Methods of Data Presentation 



1 . Profiles, Cross Sections, and Contour Charts 



Selected cross sections and profiles of observed characteristics are presented 

 for the Ross Sea portion of the oceanographic operations. Temperature, salinity, and 

 dissolved oxygen, and computed values of sigma-t are shown . 



Profiles of total magnetic intensity and bathymetry are shown together for 

 direct comparison. In addition, contour charts of bathymetry and total magnetic 

 intensity are presented for the detailed survey of Commonwealth Bay.
