Peter Birch, Google Earth Product Manager :
"We recently announced the arrival of ocean bathymetry and ocean layer content to Google Earth for Android.
Today, with the latest release of Google Earth 3.1 for iOS, we’re proud to announce that you can now explore underwater landscapes and terrain on your iPhone, iPad, and iPod touch."
Dive below the ocean’s surface to explore underwater canyons, or travel to the ocean’s deepest point, the Mariana Trench.
Once underwater, simply swipe the screen with two fingers to “look around.”
You can always reset your view by clicking on the north arrow on the iPad, or on the compass on the iPhone and iPod.
As with the desktop and other mobile versions of Google Earth, we’ve also added the “Ocean” layer, which features hundreds of photos and videos from more than 100 contributors curated by the Sylvia Earle Alliance.
This version also includes native support for the new Retina display, which means that if you have an iPhone 4 or the new iPod touch, you’ll get to enjoy an even sharper view of the world.
Google Earth 3.1 for iPhone, iPad and iPod touch is available now in the App Store, or navigate to http://m.google.com/earth in your mobile browser.
