Something Ate This Shark... But What? (Something Enormous Ate a Very, Very Big Great White Shark)

Looks like it routinely surfaced for air. Maybe Leviathan, cruising until the end of his time.

The thing that ate this shark (or the chunk of the shark that had the recording device) grabbed it and dove fast and steep to a depth of nearly 590 meters, or about 1,900 feet.

I like your analysis. But it seems to me that it is likely that the shark was captured and dragged down, as the temperature change occurred @1900 ft. And the temperature change seems pretty immediate, which would seem to negate a large chunk torn out and eaten, as something like that would tend to gradually assume the body temperature over time...
