Larsen Snd. has a lot of Old Ice in it now, but the supply of Old Ice for it runs NW all the way to Barrow Strait which should continuously feed it all season. This should give anyone transitting the NWP ice to look at all year!  Last year passengers complained there was no ice to see, but things look much different this year.  Old ice feeding into Larsen Snd./Victoria Strait making it difficult to transit used to be very common in past years - ask Frankllin!

However I can't help thinking that the "old ice" in 2017 is much less substantial than in 1846?

So are you one of those old fogies who declare everything was better in the olden days?  :o :P ::) ;D (sorry about that  :-\)

I might be old but I'm certainly not a fogie!

Be that as it may, depending on the wind and weather over the next few weeks it's not beyond the bounds of possibility that the small vessels currently heading in the direction of the Northwest Passage might encounter some problems by the time they reach the central section of the southern route:

Sept 2 1969
McClure Strait


When in the McClure strait however, ice 15' to 20' high and sometimes as deep as 100 feet proved too much for the Manhattan.

Thanks for the link Terry.
On Sept 2, 1969, the S.S.Manhattan turned her huge armored bow toward Baffin Island and started encountering her first ice floes at approx. 14 feet thick. The Manhattan, cracking off half-acre floes, sailed on without a quiver.  As the blocks grew larger,  more power was required and the Manhattan broke though ice floes as thick as 60 feet.
14ft thick in early Sept in Baffin? 60ft thick floes? Changing times indeed.

Although there can be some discussion on the current thickness of the Old ice poised to drift down to Larsen Snd. this coming summer, in the attached clip of Lndst is one of several ice island fragments that will come down with the mix,  and will certainly be thick even if nothing else is!

This is what nunavummiut think about the cruise ships: $$$

Meanwhile, heavy fuel oil is likely to soon be banned in the Arctic because it causes too much pollution -- black carbon and sulphate in particular. That development mitigates the damage of all the new shipping.

The Finnish icebreaker Nordica has successfully negotiated Larsen and Peel Sounds and is entering the Parry Channel:

No pictures of the sea ice in the area have been published yet though.
