Google Street View Takes You Underwater

Google Street View is slowly but surely conquering Earth's land surfaces, but the oceans — which cover more than 70% of our planet — are still largely untapped territory.
On Thursday, Google narrowed the gap a little by adding Street View imagery from more than 40 locations around the world, many of which are underwater. In viewers' time exploring, they've seen spinner dolphins, humpback whales and giant turtles. Google claims the images are GPS-located digital records of these environments and can be used to monitor how they change over time.
