Ever wondered how it would be to explore underwater landscapes and terrain? Now, you can get the feel. Well, almost. Because Google has released Google Earth 3.1 for iOS and the app allows you to do just that without getting into a diving gear, quite literally from the palm of your hand, on your iPhone, iPad or iPod Touch. We may recall, the search giant earlier announced the arrival of ocean bathymetry and ocean layer content to Google Earth for Android.

This version reportedly includes native support for the new Retina display. So, if are an iPhone 4 or a new iPod Touch owner, you’ll get to enjoy a sharper view. An official Google blog post revealed, “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”. Once underwater, a user needs “to 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,” Google added.

Google Earth 3.1 for iPhone, iPad and iPod touch is available now in the App Store, or through http://m.google.com/earth from your mobile browser.
