Section 14. NOAA RV Albatross IV Cruise 76-C9, 9 November. 



The vertically mixed Shelf Water/ 2-3C cooler than in the 

 previous section^ had become colder than the underlying Slope 

 Waterr beyond the 60-m isobath. Within this underlying Slope 

 Water/ the (tiinimum temperatjre ^ater lay on the bottom (<13C at 

 105 m depth)/ as in the pre\/ious section/ but was greatly 

 diminished in cross sectional area. Temperature elevation in the 

 warm Slope Water area beyond the shelf break and the deepening of 

 isotherms at. the bottom in depths below 120 m presumably 

 reflected the presence of warm core eddy 760/ centered beyond the 

 offshore end af the section (Fig. 19.2).

Section 16. WHOI RV KDQrr Cruise 62/ 21 December. 



The Shelf Water temperatures were only 1.5-2C colder than in 

 the previous section made three weeks before/ presumably because 

 of relatively mild air temperatures along the Atlantic coast 

 during December (see Chamberlin and Armstrong/ Paper 11). 

 Nevertheless/ these water temperatures/ being colder than at the 

 same time in December of the previous two years (Chamberlin 

 1978)/ did seem to reflect the unusually cold air temperature 

 that prevailed along the coast during fall 1976/ especially in 

 October and November (see Chamberlin and Armstrong/ Paper 11). 

 For example/ bottom temperatures shoreward of the Slope Front in
