THE DEPTH AND MARINE DEPOSITS OF THE PACIFIC OCEAN. 151 
As already stated, the area between 2000 and 3000 fathoms (3658-5487 
metres) in depth covers by far the greater part of the floor of the Pacific, 
and it is worthy of note that it forms an almost continuous area, for only in 
the southwest Pacific are there two separated areas: a comparatively small 
one in the Coral Sea, and a larger one in the sea between Australia and New 
Zealand, between 24° and 52°S. and 149° and 165° E., to which the name 
Thomson Basin has been given.

In recent oceanographical literature the term “ Deep ” has been applied to 
those parts of the ocean where the depth exceeds 3000 fathoms (5487 metres). 
There are altogether 31 Deeps shown on the accompanying map of the 
Pacific, and these are for the most part confined to the western half of the 
ocean. They have been named after ships which have had some connection 
with deep-sea exploration, or naval officers, geographers, or naturalists inter- 
ested in oceanography. In the preceding table are given the names, posi-
