I'd have to verify the exact estimates or the exact confidence intervals on these estimates. Again, maybe Pierre can help us.
That type of range wouldn't be unusual. We're measuring something that is over a vast ocean area and is a bit of a moving target to start with. But it is a very standard part of the way we do and present our science. We present our best estimates, but we also provide an indication of what the certainty is around those. We can provide the exact figures if you wish.
