Since the Hadal zone is so deep under water
(20,000ft - 36,000ft deep!), going there would
require using a submarine that could withstand
the immense pressures (more than 1000 times the
atmospheric pressure we are used to) at those
depths. I hope this helps!
Scientists have different opinions on how
best to explore the Hadal Zone. Some, like
oceanographer Sylvia Earle, believe that sending
manned submersibles is the best way to
understand the deepest parts of the ocean.
Others think that autonomous underwater robots,
are more suitable, arguing that these unmanned
submersibles can collect much more data. In
either case, though, designing vehicles meant
for exploring the Hadal Zone presents some
enormous engineering challenges!
