 it was in August; the depth of the top varied 

 from 40 to 90 m. The greatest depths to 

 the thermocline were in the waters which 

 lay under the eye of the storm. The isotherm 

 marking the top of the thermocline differed 



from the August condition; it was lower by

 differed from one place to another along a
