Many of us travel the world, but stick to just the green parts. Google's urging people to discover the blue parts, helped largely because Google Earth now includes layers of information and annotations for all oceans.
Last year all the oceans were 3D mapped and had video and photos added for good measure - but it's taken a while longer to add all of the information one would need in the default setting of Google Earth. Google's worked with Sylvia Earle's Mission Blue Foundation and over 100 other partners, including the National Geographic, videographers, divers and governments, to ensure every drop of water has information that can be read about it.
