Re: BBC Frozen Planet needs your advise
That sounds like something to look forward to!
We have a 60th reunion coming up soon at the base I was at and so currently I am having a lot of contact with people from that period, I will pass on your request to them.
A fairly simple thing to film that I've never seen and was always one of my favourite experiences is diving with fur seals. I have seen sea-lions and Galapagos seals in this context, but never u/w film of Antarctic Fur Seals.
Also Elephant Seals catching squid would be great.
Can't recall ever seeing film of a huge krill swarm - swimming through it with a camera.
I'll let you know if I think of more - very pleased another BBC film is to be made of the poles.
