UFO over Iceberg in Newfoundland - May 17, 2014

Witness: So I really don't know what to say about this, while driving around Salvage, Newfoundland and Labrador looking at all the icebergs, I noticed what appeared to be a chunk of ice just barely attached to an iceberg, hoping to catch it collapse I took out the camera and zoomed in.

What you can see is a white object not attached to the iceberg, but rather spinning around and changing shape?

Around 0.44-0.47 at the right of the screen another bright object splash into the water.

Bright object around 0.44-0.47

There was no fog and it was a perfectly clear day. So any ideas what this could be I'm open to all opinions, ufo, illusion or what?

This is easily the strangest thing I have ever witnessed in my life.
