On August 10th of 2012 Captain Wayne Duffett took the Canadian Coastguard Ship Henry Larson into Petermann Fjord while PII2012 was still guarding the mouth of the Fjord.
In his blog Dr Andreas Muenchow, who comments from time to time at Neven's Arctic Sea Ice Blog, gives a thrilling account of the voyage from an unexpected layover in Newfoundland, through the recovery of a 9 year old mooring that was assumed lost, to the discovery of unexpectedly warm subsurface waters in Petermann Fjord.
His first hand account of exploring waters that had been permanently iced over until July 16th of that year is so exciting even when rereading that I still haven't gotten back to looking up the PII2012-A-1 data that I'd been seeking.I'd recommend following the story from the time Andreas arrives in Canada.http://icyseas.org/2012/07/31/nares-strait-2012-first-challenges-and-petermann-ice-island-coming/Very few people throughout history have been to places where "no man has gone before".
