Note
Water is a totally alien environment for us humans.
Few of us do more than enter the sea and, as we
swim, dip our heads briefly beneath the surface to
take a momentary glimpse of a blurred and strange
world. Even the best-equipped Self-Contained
Underwater Breathing Apparatus (SCUBA) divers
can penetrate no more than a few tens of metres,
for to go deeper requires highly specialised equipment
or very sophisticated and expensive submersibles.
But imagine that, like Captain Nemo
and the crew of Jules Verne's Nautilus, we could
walk freely across the ocean floor and let us review
what we might experience if we took the long journey
across the Atlantic Ocean from Britain to the
Bahamas.
