Cariiegie-Ross New triple-size pelican snapper 

 pelican-snap- sent down for first time. Str^k 

 per; 12-oz. something at 542 m, closed and 



bottle and weights detached. Hauled up, new 



glass jar weights put on and sent down again.

Snapper not quite full of dark 

 brown clay; fairly stiff 



None 



Carnegie-Ross Snapper closed, but came up empty. None 

 pelican-snap- Enough dark brown mud on out- 

 per; vial sideof jaws for examination. Mud 



may have been too stiff to allow jaws 

 to grip when the snapper was pulled 

 off bottom 



Carnegie-Ross Snapper apparently closed going

outside

Carnegie-Ross Snapper was full of dark brown 

 pelican-snap- mud, as for all previous sam-

terial, probably mostly clay minerals, is present. Feldspar, hornblende, and a few manganese grains 

 also were identified. 



Sample 69. Remains of organisms are fairly common, and include radiolaria, sponge spicules, arenaceous 

 foraminifera, and fish teeth. In addition, the sand grades contain cleavage fragments of brown hornblende 

 (-2V=80), plagioclase feldspar (andesine, AbgoAn4o), and round manganese grains. 



Sample 70. Sand grades are very small in amount. Remains of organisms are principally diatoms, togeth- 

 er with radiolaria, sponge spicules, arenaceous foraminifera, and fish teeth. Round manganese-iron 

 grains of sand size are also present. 



Sample 71. Very small, fine-grained sample. Contains very few remains of organisms, chiefly radio- 

 laria. Also contains augite, orthoclase, hornblende, plagioclase (andesine), basic volcanic glass, and 

 manganese.
