pretrips, a Nansen bottle was placed directly above the Bodman bottle, 

 and salinities of the two samples were compared. The Bodman bottle 

 samples were stored in 15-gallon containers and returned to Dr. Anderson. 



The six core samples obtained with the special piston corer were 

 frozen immediately after they were collected and were forwarded to 

 Dr. Anderson for radiological examination at the end of the survey. 



The 95 Kullenberg gravity cores, averaging about 1 to 2 meters 

 in length and 5 centimeters in diameter, were collected in plastic 

 (Tulox) liners, wrapped with Saran Wrap, and covered with a thick 

 layer of wax. These cores were divided between the University of 

 Wisconsin and NAVOCEANO. The cores, when opened at NAVOCEANO 3 to 

 4 months later, had suffered very little desiccation. They were analyzed 

 for specific gravity, moisture content, organic carbonates, bulk density, 

 porosity, lithology, and grain size. 



The 48 bottom grab samples were taken using either a Shipek grab 

 or a weighted orange peel bucket sampler. These samples were divided 

 between the University of Wisconsin and the Smithsonian Institution. 

 The Smithsonian Institution samples were preserved with dilute alcohol 

 and sealed in pint jars for foraminif eral examination. 



Two current stations were taken in the Kara Sea. The first, while 

 examining a shoal area, was of 4 hours duration. The second was taken 

 for 24 hours to obtain information for a full tidal cycle. The current 

 meter used (Photo 6) was a Hydro Products Model 460 current speed 

 sensor (Savonius rotor type) and Model 465A current direction sensor. 

 Both sensors were connected to deck readout modules and Rustrak recorders. 



Continuous bathjrmetric profiling was done along the entire track 

 of the survey using an Alden Precision Graphic Recorder (PGR) Model 

 418. At half-hour intervals, the PGR record was annotated with the 

 date and time. 



Using a Gifft transceiver in conjunction with the PGR, a continuous 

 subbottom profile was recorded along with the bathjmietry for much 

 of the track of the NORTCTJIIID . Bottom penetration was possible due 

 to the variable pulse length of the transceiver and the shallow depths 

 of the survey area. 



Ship positioning was unusually accurate due to the installation 

 of a Satellite Navigational System (SRN-9) designed by the Applied 

 Physics Laboratory, Johns Hopkins University. The accuracy of this 

 system was about 500 feet. 



F. Data Analysis and Presentation. 



Oceanographic station data were checked, coded, and forwarded 

 to the National Oceanographic Data Center (NODC) . Machine computations
