Given that water covers roughly 70% of our planet, it makes sense that Google Earth should take the oceans into account. Thanks to a partnership with the California Academy of Sciences, Google Earth now offers, according to the company blog, detailed maps of the ocean floor "so you can actually drop below the surface and explore the nooks and crannies of the seafloor in 3D." You'll also get "thousands of data points including videos and images of ocean life, details on the best surf spots, logs of real ocean expeditions, and much more."
In this latest release of Google Earth, you'll also find detailed maps of the planet Mars, plus (rather amazingly) some functionality that lets you see how landscapes have changed over time. How does San Francisco look today as compared to 50 years ago? You should now be able to find out.
