You never get the final answer in a biological system.

But, Lowell, here's the answer to your question about how far sea ducks dive for food.

The Audubon Water Bird Guide says 20 to 30 feet for some---scoters etc---but King Eider have been caught in gill nets at depths of 150 feet.

You're welcome, sir.
