Given our limited knowledge, exploration of the oceans continues to lead to discoveries in various scientific fields.As with the discovery of the Esmeralda, many archaeological finds are made in shallow waters near the coast.These may sometimes include whole cities buried beneath the waves.One such find is the ancient Roman city of Neápolis, discovered off the coast of Tunisia.Believed to have been buried underwater by a tsunami in the fourth century AD, the ruins of Neápolis are almost 2,000 years old.The remaining streets and buildings offer a window into a fascinating period in our history.However, we are only beginning to overcome the challenges of pressure, darkness and extreme cold at vast depths.Fragments of the past lying deep beneath the oceans are still waiting to be discovered. Amazing biological discoveries are also being made.The dark zones of the oceans may contain up to 90 per cent of the planet's fish.In these waters, more than 200 metres deep, are extraordinary creatures that appear Imagine bone－white coral 6,000 metres below the ocean's surface, growing at the rate of only one or two millimetres per year.Some of these could be 4,000 years old.Swimming through these black depths is the barreleye, a strange fish with eyes that can look upwards through its transparent forehead.In the very deepest ocean trenches that are more than 8,000 metres below the surface, the pressure is equivalent to 50 aeroplanes stacked one on top of another.Yet there is still life to be found, even around the deep－sea volcanic openings.These discoveries all help us understand the capacity for life on our planet, even in the most extreme circumstances. Furthermore, the oceans are a valuable source of natural resources, some of which are completely new to us.Most notable of these is China's discovery of an ice－like substance, known as “fire ice”， under the South China Sea.In addition, China's underwater vessels, such as the Jiaolong and Shenhai Yongshi, have been exploring waters at depths of thousands of metres.The Jiaolong even holds the record for the deepest dive by a manned submarine, at 7,062 metres, giving China its place alongside the world's top ocean explorers.The research conducted by these vessels is giving scientists a greater understanding of how the sea bed was formed, as well as helping identify areas for deep－sea drilling, taking deep－sea exploration into a whole new era. Being a tough environment of complete darkness, enormous pressure and intense cold, the ocean depths have long been beyond the reach of human exploration.However, through closer international scientific, economic and cultural cooperation, we are all becoming part of a global mission to open up our planet's final frontier.Humankind is entering a new age of oceanic discovery, and the world beneath the waves may one day be almost as familiar to us as the land we walk upon today.
