ing southward. The warm ( >0 °C) water did not 

 appear in Smith Sound and could only have 

 originated in Baffin Bay and flowed northward. 



Cape Norton Shaw-Cape Parry 



The Cape Xorton Shaw-Cape Parry section 

 was occupied twice. The temperature sections 

 (figs. 11 and 12) indicated a temperature struc- 

 ture similar to that in the Smith Bay-Hvalsund 

 section. Maximum temperatures higher than 

 + 1°C occurred in the deep east of the Carey 

 Islands and lower temperatures, characterized by 

 a minimum below — 1.20°C between 100-200 m, 

 were found in the central and western portions 

 of the section. A mass of warm (0°C) water 

 occurred just west of the Carey Islands between 

 200-400 m and was more pronounced on 8 Sept. 

 (fig. 11) than on 21 Sept. (fig. 12). A relatively 

 warm {— 1.00°C) layer occurred at .50-100 m 

 depth in the westernmost portion of the section 

 of 8 Sept. (fig. 11) and may have been a re- 

 flection of local seasonal warming. 



The vertical sections of salinity (figs. 13 and 

 14) indicated a variation in salinity from less 

 than 32%o near the surface to greater than 

 34.4'''(K) near the bottom, with maximum salinity 

 occurring in the regions of maximum tempera- 

 ture. The isohaline slopes indicated a net south- 

 ward baroclinic flow of the cold water in the 

 central and western portions of the section, while 

 tlie warm tongue west of the Carey islands ap- 

 peared to flow northward on 9 Sept. (fig. 13) 

 and to be nearly motionless on 20 Sept. (fig. 14). 

 The warm water east of the Carey Islands ex- 

 hibited a southward flow in the earlier section 

 which had become northward by the later occu- 

 pation of the section. Near-surface colder water 

 east of the Carey Islands flowed northward dur- 

 ing both occupations of the section and probably 

 originated from the near-surface cold water 

 layer of Baffin Bay. 



Cape York-Smith Sound 



The longitudinal section (fig. 15) east of the 

 Carey Islands indicated a pronounced thermal 

 front between stations 29 and 30, with warm 

 (> + l°C) water occurring below 300 m north 

 of this front as far as station 32 and in the topo- 

 graphic deep at stations 36 and 37. A relatively 

 warm (>0°C) tongue extended northward at 

 300-400 m depth to station 42, north of which 

 only cold water similar to that found in Smith 

 Soiuid occurred. The water laver between about 



50 m and 150 m was characterized by irregular, 

 relatively low (<0°C) temperatures. The partial 

 longitudinal temperature section from Cape York 

 to east of the Carey Islands (fig. 16) indicated 

 that the temperature structure was essentially 

 the same at this later date (19-20 Sept.) as dur- 

 ing the earlier occupation on 11-17 Sept. 



The earlier vertical salinity section (fig. 17) 

 indicated a salinity variation from less than 

 32''/6o near the surface to greater than 34.4%o near 

 the bottom, similar to the variation found in the 

 latitudinal sections. The later, partial section 

 (fig. 18) indicated a variation from less than 32%o 

 near the surface to a maximum of .34.399bo near 

 the bottom, so that maximum salinities were 

 slightly lower at this later date. 



The isohaline slopes on 11-13 Sept. (fig. 17) 

 indicated a westward flow between stations 29 

 and 30 and an eastward flow between stations 30 

 and 31. A slower westward flow occurred between 

 stations 31 and 36 and an eastward flow was 

 indicated between stations 36 and 38. Tlie pattern 

 of alternating flow directions continued north- 

 ward with westward flow between stations 38 

 and 42 and eastward flow between stations 42 

 and 44. On 19 Sept. (fig. 18) an eastward flow 

 was occurring below about 200 m between sta- 

 tions 67 and 68 while a less intense westward 

 flow was occurring between stations 68 and 72, 

 again below 200 m. An eastward flow occurred 

 below 200 m between .stations 72 and 75. Little 

 flow was taking place in the upper 200 m of the 

 section, as compared with the earlier section 

 wjiere flow generally extended upwards to the 

 surface. The flow below 200m was similar to that 

 for the earlier section if a shift to the south by 

 about 10 nm was supposed for the entire pattern. 



Smith Sound-Carey Islands 



The two temperature sections (figs. 19 and 20) 

 indicated lower overall temperatures than east 

 of the Carey Islands. The warm tongue at 200- 

 300 m had maximum temperatures of only 

 4-0.o°C that extended northward to station 16 on 

 10 Sept. (fig. 19), but not as far north on 15 Sept. 

 (fig. 20). Xear-surface temperatures were irregu- 

 lar and low, grading northward into the uniform- 

 ly cold water of Smith Sound. "Blobs" of warm 

 and cold water imply the southern section (fig. 

 19) to fall across a zone of turbulent mixing 

 between the wanner water originating in Baffin 

 Bay and the colder water flowing southward via 

 Smith Sound. Tlie absence of temperatures as
