THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 159 
On comparing this map with the deposit map it will be observed that 
away from the coast the deep shades correspond with the Globigerina and 
Pteropod Oozes. Thus the outlines of the principal Globigerina Ooze areas 
are almost exactly reproduced in the darker shades of green. Again, the 
faint shades of green on the map correspond with the areas showing Red Clay 
and terrigenous deposits excluding coral deposits.
