Why the Titanic sub is so hard to find!

search teams are racing against time to
find a tourist submersible that went
missing during a dive to the Titanic's
wreck the search is taking place in a
remote area which makes the operation
especially challenging communication who
water is always very difficult so once
you've lost communication it's very
difficult to locate where it is one of
the big problems with the research is
that they don't know whether to look on
the surface of the Atlantic or the sea
Bank could be in either place it's very
unlikely it's in between a very deep
water column so to try and find your
items or your footprint of your search
will be really big and then you'll have current effects as well so if the subs
somewhere in the water column it can be
moving around in a non-predictable
manner the submersible vanished in the
ocean approximately 900 miles from Cape
Cod Massachusetts where the ocean depth
is roughly 13 000 feet if it's on the
surface of the ocean it's going to be
very difficult to spot because as it's a
submersible it's designed to be mutually
buoyant
so it'll be floating just at the surface
most of it under the water of just a
small amount uh breaking the surface and
it's about the size of a large Transit
van so and it's painted white so trying
to
see that for me air particularly if
they've lost power so they won't be able
to signal is going to be a real
challenge
an additional complication is that the
crew cannot get out on their own they
are bolted in
so they're trapped inside so it makes
signaling more of a challenge if it is
on the sea bed it won't be so much a
case of looking for them but listening
for them because we'll be using Sonar
and
hopefully the crew will then be making
some sort of noise on on the hull which
can be detected.
