We have selected Oceans Alive! as the world's very best website on Oceans.

The Oceans Alive! website is published by the Museum of Science, Boston, Massachusetts, USA. It is organized into five main sections: The Water Planet, Oceans in Motion, Life in the Sea, Scientist at Sea, and Resources. 

The Water Planet is a section explaining that 71% of the Earth's surface is water. It contains articles on: Physical Features of the Ocean, The Changing Oceans, The Water Cycle, and Ocean Profiles. Ocean Profiles includes quick facts on each ocean; for example, the Pacific Ocean makes up 48% of all the worlds oceans in terms of area, and is 36,200 deep at its deepest point in the Mariana Trench, enabling it to swallow Mount Everest with ease. The Water Cycle section includes do-it-yourself instructions for making a model of the water cycle out of two half gallon jars, a rock, masking tape, and food coloring. The Oceans in Motion section includes articles on: Ocean Currents, Wind & Waves, and the Ebbs & Flows of the Sea. The Scientist at Sea section contains articles on Underwater Exploration and Remote Sensing.
