Bathyscaphe Trieste (1958-1963) in 1959-60



In October 1959, after being fitted with a stronger pressure sphere, Trieste was transported to the mid-Pacific to participate in Project "Nekton", in which she conducted a series of very deep dives in the Marianas Trench. On 23 January 1960, she reached a record depth of 35,800 feet in the Challenger Deep, off Guam, the deepest point in any of the World's oceans.

This page features views of Trieste in 1959-60, during Project "Nekton".

Just before her record dive to the bottom of the Marianas Trench, 23 January 1960. The dive, to a depth of 35,800 feet in the Challenger Deep, off Guam, was made with Lieutenant Don Walsh, USN, and Swiss scientist Jacques Piccard on board. Waves were about five to six feet high when the two men boarded Trieste from the rubber raft seen at left.

Jacques Piccard, co-designer of the bathyscaphe, and his assistants make final checks aboard her, prior to Trieste's first deep dive in the Marianas Trench. On 15 November 1959, off Guam, she dove to 18,600 feet, breaking the previous record of 13,000 feet.
USS Wandank (ATA-204) is in the distance, apparently towing the bathyscaphe. Navigation bouy on right indicates that the photo may have been taken as Trieste left port to make the dive.
