I'll throw the question out quite quickly to Mr. Cadigan. Near the end of your presentation you talked about seismic vessels and some of the impediments to doing exploration. We see your graph here, and there was a lot of exploration through the 1980s and into the 1990s. By 2000 exploration has dropped off.
Obviously seismic testing is one of the first things you do. You mentioned there were some impediments to vessels in doing seismic work. Could you elaborate on that?
