FIGURE 13. Surface Salinity Distribution - Taken from Vize (1933) 



Cross sections, Figures A-2 through A-23 (Appendix) ,• show in 

 sectional view the water types present in the t^ara Sea. The surface 

 vrater runoff is particularly well depicted in sections A-A' (Fig. A-2) 

 through M-M' (Fig. A-14) . In the sections lying between Novaya Zemlya 

 and the Siberian Coast, the runoff is found at very shallow depths. 

 This pattern remains true until section !i-H' (Fig. A-9) where the 

 n^C isotherm dips steeply at station 42. This abrupt d5-p probably 

 has a number of causes rather than being due primarily to river runoff, 

 e.g., the surface movement of Atlantic Water around the tip of Novaya 

 Zemlya and the estuarine effect as deep Atlantic Water, sections J-J' 

 (Fig. A-11) and V-V (Fig. A-23), moves into the Kara Sea from the 

 Arctic Ocean to compensate for the outflow of surface waters . Based 

 on older and less complete data, Coachman and Barnes (1962) went 

 into some detail in reporting on this estuarine effect "...Dynamics 

 similar to those in estuaries develop over the edge of the continental 

 shelf and in the canyons; the surface water moves off the shelf and 

 the deeper water moves toward the shelf and up the canyons where 

 it attains deptlis considerably shallower than it occupies in the
