Early History
Surveying began at the coastline but slowly inched
outward towards the sea. First research included; the
studies of tides and tidal currents, the collection of
samples to determine characteristics for the
anchoring of vessels, and noises, to determine the
depth and physical features of water near the coast.
*
The first people to venture into the sea explored the ocean close to the
shore. The Greeks and Chinese were the first societies who went deeper into
sea. They were diving into the ocean to gather food and collect shells .
*
In the mid 1500s, Europe became interested in what was beneath the waves.
With crude helmets and diving bells, they were able to spend only a very
short time in shallow waters, but they were able to see plants and fish that
were not visible from the surface.

the ocean,
were
developed.

Jacques Cousteau created one of the first
underwater methods of breathing, he called it
the “Aqua-Lung”. The “Aqua-Lung” is a
device created to allow divers to dive
deeper for longer periods of time. It was
made of a regulator and three
cylinders of air.
The future of Ocean Exploration
The Sea Orbiter
The Sea Orbiter will be the world’s first
vertical ship 51m high it will allow man a
view of life below the surface. It is still
only a prototype invented by Jacques
Rougerie but will soon become a reality.
The Sea Orbiter will provide a permanent
mobile presence with windows under the
surface of the sea. It will cost
£32million to build the first Sea Orbiter.
As well as ocean exploration the Sea
Orbiter would also be a useful tool for
studying the link between global warming
and the oceans.
