This mysterious footage was found on YouTube from the channel "Sea Creatures of the Deep". The audio has been edited as the original contained music. I suspect the original uploader blurred the expedition logo and added music to cover the radio chatter. After days of searching I could not find the original audio - apologies for this.
The details of this observation are as follows:
Date: February 23, 2013
Depth: 2,391 meters ( 7,846 feet)
Location: Gulf of Mexico (not confirmed).
