 times as deep as do the samples off Cape Murchison, yet the deposits 

 have the same texture. Similarly the sediments east of Resolution 

 Island show that the bottom configuration influences the deposits 

 more than depth of Avater. The normal progression of decrease in

texture with increasing depth of water is interrupted by sample 17 

 on a relatively steep slope in 950 meters of Avater. The median of 

 sample 17 is 62 microns, but sample 18 situated nearer shore in 250 

 meters less Avater, has a median of 20 microns. The section east- 

 ward from Aulalsivik. likewise, demonstrates the relative lack of 

 influence of depth of Avater on the texture. Samples 20 and 21 lying
