The great deeps of the Pacific are:— Aldritch Deep, north-east of New Zealand, 5,902 fathoms, and east of Tonga, 5,022 fathoms.
Challenge Deep, as above.
Swire Deep, off Mindanao (Philip pines), 5,902 fathoms—the greatest known sounding.
The waters enclosed by New Britain, New Ireland and the Northern Solomons (that is, about due southwards of Rabaul) reach about 5,000 fathoms.
