suggesteo that distortion mey also occur when wind causes 

 overrunning of an eddy by surrounding water/^ or chilling of 

 an eddy at the surface. 



This report and that of Bisagni (see footnote 2) demonstrate that 

 eddies have a variable^ Dut major* influence on physical 

 conditions in the Slope Water. During the three years of record/ 

 the number of eddies oresent at any time has ranged from a low of 

 one (November 1974 to mid-January 1975) to as many as six (early 

 November 1975/ one of which/ 751/ was not recorded by Bisagni). 



SUMMARY 



Two we I L -de vel oped anticyclonic eddies (751 and 76A) occurred 

 south and southeast of Georyes Bank in the early months of 1976/ 

 but these were short lived. Only three eddies moved westward 

 beyond Georges Bank during the year (76B/ 76C/ 76D). Although 

 two of these/ 76B and 76C/ were apparently weakly developed/ the 

 former probably moved at least to the vicinity of the Hudson 

 Canyon/ and the latter to the latitude of Virginia. Eddy 76D was 

 strongly formed. It moved to the vicinity of the Hudson Canyon 

 by the end of the year.

 tionary Orbiting Environmental Satellite. Rudolf J. Perchal/ 

 U.S. Kaval Oc ea nog rap hi c Office/ provided up-to-the-minute 

 satellite information at times when research vessels were making 

 special observations in eddies. Philip L. Richardson/ University 

 of Rhode Island/ provided NOAA-4 satellite pictures for the

Henry ti . Jensen provided special X6T observations south of 

 Georges Bank from RV Aigatros^ IV on 2-3 April. Special acknowl-
