PHOTO 2. Close Ice 



this line, grease ice and pancake ice were encountered, and at 80°E, 

 the ice increased to close pack. Hov/ever, the existence of polynyas 

 permitted oceanographic stations to be taken. Close pack also was 

 found along the southeast and southern coasts of Franz Josef Land. 



D. Survey Accomplishments. 



A total of 163 oceanographic Nansen stations was occupied in the 

 Kara Sea and adjoining Barents Sea (Fig. 5). At these stations, 1,814 

 serial-depth temperature, salinity, dissolved oxygen, nitrogen, and 

 pH observations were obtained. In addition, 1,797 water samples were 

 frozen and returned to NAVOCEANO for determination of reactive phosphorus 

 and reactive silicate concentrations. Also, bathythermograph lowerings 

 were made at 151 stations, IS samples were taken in a program of 

 continuous air sampling, 25 nannoplankton samples were obtained, 6 

 plankton tows were taken x/hile drifting on station, 35 thirty -gallon 

 water samples were collected for gamma-radiation analysis, 48 bottom 

 sediment grab samples were collected, and 95 gravity cores were taken 

 in areas of water depth in excess of 200 meters. A special piston 

 corer (Photo 3) was used to obtain six cores. These cores were collected
