Figure E-4. Thermal Structure of tfie Water Columr}. 



These figures depict the thermal structure along four expendable BathyThermograph transects taken during 

 the IIP June 1987 study. These transects were nearly orthogonal to the flow of the Labrador Current. The 

 XBT positions are noted by cast numbers along the top of each figure. The geographic positions of the 

 transects are shown in Figure E-5. Figure E-4a depicts transect A1, which was measured between 0645Z 

 June 15 and 0631 Z June 16. Figure E-4b depicts transect 81, which was measured between 1949ZJune 14 

 and 0151Z June 16. Figures E-4c and E-4d represent transects taken about 4 days-later approximately 74km 

 downstream from the A 1 and 31 transects. Figure E-4c depicts transect A2, which was measured between 

 081 9Z June 19 and 1234Z June 20. Figure E-4d depicts transect 32, which was measured between 0429Z 

 and 2008Z June 19.
