There is a good discussion on the BP website and at theoildrum.com.....they do plan to gradually close the valves, are still worried about ice because water could seep in under the device...and, yes, it does look like more of the finds are able to be seen.
Sorry, I should’ve used the term “fins”. That’s what I meant. LOL.. I suppose they didn’t have time to integrate heating elements into the unit? I don’t even know if that would be “physics friendly” at that depth. All I know is, the entire process is far more complicated than the average Joe can comprehend.
