Figure 2. Oceanographic stations occupied in the Laptev Sea during the 1963 NORTHWIND cruise. 

 Stations ore numbered consecutively in order of station occupation. 



All oceanographic station occupation, chemical analysis, and 

 shipboard data reduction were accomplished by NAVOCEANO and University 

 of Washington personnel with supporting assistance from officers 

 and crew members of both ships. 



III. METHODS AND PROCEDURES 



A. Sampling Techniques. 



Serial-depth Nansen cast observations were made from surface 

 to bottom at all stations occupied in an attempt to obtain representative 

 samples throughout the water column. A single cast was considered 

 adequate for providing coverage at all stations. 



Water depths, typically less than 50 meters (164 feet), precluded 

 the use of unprotected reversing thermometers for determining themometric 

 depth values. A satisfactory approximation of sampling depth was 

 obtained using the cosine of the wire angle multiplied by the amount 

 of wire out. This simple method was feasible because of the very 

 shallow water involved, the low wire angles encountered, and the 

 close observation maintained on the meter wheel.
