Dear traceym-ga;
Thank you for allowing me to answer your interesting question. I?ve
spent quite a bit of time seeking out the information you are needing
for your article and I believe I have been able to find a great deal
of very interesting photographs and information.
THE EXPLORATION:
The trench has a maximum depth of 10,924 m (35,840 ft). It was fully
surveyed in 1951 by the British navy vessel, Challenger II, which gave
its name to the deepest part of the trench, the Challenger Deep.
The only manned exploration of the deepest portion of Marianas Trench
took place on January 23, 1960 when U.S. Navy Lt. Don Walsh and Swiss
scientist Jacques Piccard courageously took the bathyscaphe Trieste to
the bottom of the Challenger Deep of the Marianas Trench, the deepest
spot on Earth. No human has ever attempted the feat again. Here you
will find a fascinating animation along with a chilling account of the
first decent to the bottom of Challenger Deep in the Mariana Trench by
Jacques Piccard and Don Walsh in 1960 aboard the Trieste. According to
Piccard, "The bottom appeared light and clear, a waste of...firm
diatomaceous ooze.":

This vertical map shows the actual descent path of the Trieste on its
voyage to the bottom:

THE TRIESTE:
Here you will find some fairly high-resolution photos and wonderful
details about the specifications and capability of the bathyscaphe
("bathy" = deep, "scaphe" = ship) Trieste was built in 1953 at Naples,
Italy, by the Swiss scientist Auguste Piccard:

THE EXPLORERS:
Pictured here are Lt. Don Walsh, left, and Jacques Piccard in the
bathyscaph Trieste moments before the actual harrowing dive to
Challenger Deep in Mariana Trench. Keep in mind that neither of these
men knew if they would ever return alive:

This is one of the only color photographs of the explorers I found
taken at the time of the 1960 dive to the bottom:

THE MARIANA TRENCH AND CHALLENGER DEEP:
Here you will find biology reports on the samples obtained from the
Trench floor by Japanese submersible Kaiko on March 2, 1996:

This is an excellent graphic the puts the magnitude of the trench in
perspective by comparing the depth of the Mariana Trench to the height
of Mount Everest:

Geophysical Data Center, is representative of what one would see,
based on topographical maps of the ocean floor, if he were to ?fly?

LIFE IN THE TRENCH:
This is an image of a ?Fangtooth? (Abyssobrotula galatheae), one of
the deepest dwelling fish known (This particular specimen was found in
the Puerto Rican Trench at a depth of 8,372 meters, or over five miles
down!) and this frightening looking Viper Fish (Chauliodus sloani)
that can be found about one mile down:
