Seeing an upside-down iceberg may not sound all that interesting, that is until you actually see how what one looks like. And if the images from Alex Cornell weren't enough, we get an in-depth look at how the adventure went down.

First, I must mention, these photos are amazing because of the spectacular subject matter. Just as if I photographed a whale backflipping through a rainbow, there was nothing remarkable required on my part to acquire the shots. I was lucky to be in the right place at the right time, with the right gear.
