I completely agree with that.
We are well aware that sonobuoys and visual surveillance using aircraft aren't perfect tools. The reopening of an area requires two surveillance flights during the period. Sometimes the weather prevents aircraft from taking off, but the buoy is still there. If it doesn't detect right whales, that should mean there aren't any in the area. A buoy provides information that can be used to close an area, but not to reopen it. I think that should change.
