Deep ocean mysteries and wonders

Most of Earth's surface lies hidden beneath water, with an average ocean depth equal to fifteen stacked skyscrapers.

The deep sea is home to ecosystems richer in diversity than any tropical rainforest. Our understanding of the planet remains incomplete until we venture further into these mysterious depths.
