How do we see into the sea?
Even the most aquatically capable of us mere puny humans can only
descend into the sea for a few minutes at best without the aid of
technology. To study the sea requires that we observe it through a
variety of means over protracted periods of time. Some of the ways
we do this are by carrying our own Self-Contained Underwater Breathing
Apparatus (SCUBA) or having air pumped down via a hose, using unmanned
tethered vehicles that are towed behind a vessel to photograph or
sense the seafloor and water column, riding in piloted manned submersibles,
or by programming autonomous underwater vehicles. Learn about some
of the technology available to let us study the sea, the creatures
in it, and the nature of the seafloor….
