Earth is distinctively different from other planets due to the presence of water with the world's oceans covering more than 70% of the Earth's surface and supporting an enormous variety and abundance of life.However, despite their vast presence and the fact that they contain 97% of our world's water, 95% of the ocean remains undiscovered particularly at it's deepest depths. Increasing numbers of people are exploring areas of the ocean floor that have not been visited previously, with some remarkable discoveries being made.
