Would a report on a recent expedition to places mentioned above be useful.Mind you, I don 't want to spoil article for Anne and Flying Fish
Not sure how this forum works!

Steve,
You seem to have got the hang of the Forum and thank you for the link. We are heading to Greenland in 2016 so may well be in touch. We won 't be heading for the NW Passage though but will go onto Labrador instead.
