I do. On the west coast, with respect to the resident killer whales, we were proposing that pilots' personal portable pilotage units, which they carry, could be adapted so that if you had an array of sonobuoys, we would be able to know exactly where the various pods were located. Right now we are slowing down virtually every single ship through quite a large area, significantly adding to their time through the water and hopefully reducing the noise signature, but you don't really know whether there are any whales there at the time you are doing this.
Hopefully, if we can get this technology moving ahead, we can then differentiate and slow down when we have to slow down or else keep the speed up if there is nothing in the immediate area.
