The ocean is the source of all life. With every drop you drink and every breath you take, you are connected to the ocean no matter where on Earth you live. Oceans generate 70% of the oxygen in the air, and absorb much of its carbon dioxide. They drive the climate, the weather and the chemistry of the planet. Our oceans occupy over 2/3 of the planets surface and provide a home for most of the creatures on Earth. Unfortunately, our knowledge of the ocean is far outstripped by our impact on it. Although time is running out, it isn't too late to expand on our understanding of the worlds oceans, and to use that knowledge to effect positive change.
