Google Ocean

Google Earth has had a big update to provide us with even more science and geekness. The latest update includes Google Ocean, where you can view the 3D topography of the ocean floor, track pods of whales that have been fitted with global positioning systems, view up-to-date info on lots of marine life and check out plenty of photos, especially showcasing our own Great Barrier Reef.

It'll have to do until we can go SCUBA diving again.
