ACKNOWLEDGMENTS 



The author is indebted to the U.S. Coast Guard for 

 the opportunity to participate in the WEBSEC studies. 

 Appreciation is extended to Captain Robarge and the 

 officers and crew of the Glacier for their interest and 

 assistance in sampling. Particular thanks must be 

 given to those of the marine science department for 

 their willingness to brave the wind and cold in order 

 for the scientists to obtain data from an area and time 

 period not normally covered by arctic investigations. 

 Oceanographic data discussed in this report were sup- 

 plied by cruise leader Merton Ingham of the Coast 

 Guard Oceanographic Unit.
