and acco and, colleen, to you, a couple of final questions. what are the chances of a debris feef, that is a collection of a things given that area of the world and the currents. >> you're talking any debris. >> floating. i assume it moves underneath the water as well and hasn't settled all the way down to the bottom. >> we use that term both for the stuff you find floating on the ocean and the stuff on the bottom. the stuff at the bottom is going to stay there. it's heavy. it's going to stay there. i don't think the currents are very strong on the bottom of the ocean. it's on the top where winds generate the water that's where the currents are moving very fast. people say there's going to be floating debris this far into the problem. so i would still expect to find some objects still floating
