 Located beyond the offshore Limit of the section (Fig. 19.2) was 

 presumed to have been the source of the isoLated body of 13-14C 

 water centered at about 90-m depth in the SLope Water zone.

Surface temperatures were warmer than in the previous section 

 (section 9) r made two weeks oefore^ but remained about 2C cooLer 

 than in section &/• made prior to hurricane BeLLe. (In Later 

 sections/ surface temperatures were aLso cooLer than in 

 section 8/ except in section 12 made in earLy October.) The 

 therrrocLine was nearer the surface than in section 9^ but 

 remained deeper than in section 8 and Less sharpLy defined. SLow 

 warming was apparent in the coLd core water/' which aLso had a 

 "calving" tendency at its offshore margin.

Surface temperatures were about the same as in the previous 

 section/ made a month earlier/ but were 2C warmer in the cold 

 core bottom water/ which had minimum temperatures >11C and was 

 divided into two cells. The slope front had become thermally 

 indistinguishable near bottom/ because the cold core water had 

 warmed to about the same temperature as the adjacent warm SLope 

 Water (see Wright 1976). The domed feature in the upper 30 m at 

 XBT stations 5-6 may be a cyclonic eddy from the slope front.
