Google teamed up with the Catlin Seaview Survey, which is sponsored by the UK-based insurer Catlin Group, to produce the new images.
The Survey used its custom-built SVII camera to photograph the 360° panoramas, which capture turtles, fish and manta rays in their natural environment. The camera, one of only two in the world, takes pictures every three seconds while travelling at around 4kph. The resulting images are stitched together digitally. The underwater panoramas will eventually comprise 50,000 images, according to the Survey.
Users can zoom in on the ocean views, although you can't yet 'walk' around, unlike in Google Street View.
