Yeah and that map is quite a few days out of date (or at least when I compare it to the positions provided by individual boats). So there's plenty of ice in the passage but more than enough clearance for the boats to manage just fine.

A few yachts seem to waiting near the western entrance to Bellot Strait before heading south, whilst both Philos and Selma seem to have made it through the strait:

I think S/V Selma was just ahead of them and maybe Snow Dragon II is in the same area.

Salty Kisses making good progress (~5kts) should pass Jenny Lind Island soon.
They appear to have anchored there now.

The Northwest Passage tracker is still at least a day behind but up to  the point where Salty Kisses pulled in and stopped at Jenny Lind Island it is showing identical paths for S/V Snowdragon II and S/V Bagheera. This includes the stopover just north of Bellot and the same stopover at Jenny Lind.

Next stop Cambridge Bay perhaps?

First reasonably clear satellite image since a while:



I'm intrigued by that cappuccino ice in the middle of the NWP. I don't think I've seen it often there.

Here's a close-up on EOSDIS Worldview.

Here is the current status of all nine NW passage boats tracked at www.thenorthwestpassage.info. At least two are through, and all the rest are in good shape to complete the passage in the coming days:

1. Andros (west-to-east) has passed through Bellot Strait and also Hecla and Fury Strait, and is in the middle of Foxe Basin. Since it's barely north of the Arctic Circle, it will technically complete a northwest passage in the very near future.

2. Aventura has completed a west-to-east passage and is near Nuuk, Greenland.

3-4. Bagheera and Snow Dragon II, traveling together east-to-west, are in Cambridge Bay.

5. Hawk, traveling east-to-west, is approaching Gjoa Haven.

6. Necton has completed a west-to-east passage.

7. Philos, traveling west-to-east, was at the east end of Bellot Strait on August 13, and has not reported a position since. Assuming nothing bad happened, it has probably completed its passage by now.

8. Salty Kisses, traveling east-to-west, has completed its traverse of Coronation Gulf (see previous post) and entered Dolphin and Union Strait.

9. Selma, traveling east-to-west via Bellot Strait and Gjoa Haven, has reached Cambridge Bay.

Your welcome, Phil.

A couple further notes: Andros appears to be the first boat to ever go west-to-east via Hecla and Fury Strait and the Foxe Basin, and only the 4th in either direction. Of the 9 passages lsited for this year, Hawk is the only one following Amundsen's original 1903-06 route.

The main Northwest Passage is within a whisker of being passable without encountering ice concentrations greater than 3/10. I’m therefore eagerly awaiting the August 29th release of the Canadian Ice Service sea ice concentration maps!

There may possibly be a way around the north of Byam Martin Island, but the CIS resolutely state “No analysis” in that area. I guess that wouldn’t really count as the Parry Channel either. For the moment at least, there’s still an area of 9-10/10 concentration blocking the way:

A slightly cloudy MODIS image is now available:

http://GreatWhiteCon.info/resources/arctic-regional-graphs/northwest-passage/#Aug29

With a bit of luck an intrepid navigator in a motor yacht could probably make it through the remaining ice via a circuitous route. Personally I don't think that's  enough to declare the passage "open" just yet, but others may disagree!

I've been observing the arctic ice melt since 2009. This is the closest I've seen the Northwest passage to being open, without it being "officially" open.

Jim & Diablo: according to the Canadian ice services ice maps my conclusion is that Amundsens Route now is entirely open.

Parry Channel may be closed right now but there is still an opportunity that it may open up temporarily as the surge of warm air in combo with southerlies will weaken the ice enough to call it "open".  Diablos ice chart shows that the ice blocking the channel actually have weakened as the ice there now "only" is of 7-8/10. From previous day it was 9-10/10.

The warm air seems to be in place in the area for about another 48 hours. Beyond that I don't expect much more melting in this area.

If my memory is correct, both passages were open simultaneously in 2008 and 2012. Were they both open in 2007?

In today's chart the CIS have "no analysis" in the thickest remaining ice in the Parry Channel :(

Amundsen's route certainly looks "open" however.

According to the latest edition of Arctic Sea Ice News:

The southerly route through the Northwest Passage is open. Data from the AMSR-2 satellite, which uses passive microwave emission, suggests that this path is ice-free. The higher-resolution Multisensor Analyzed Sea Ice Extent (MASIE) product, based on several data sources and human interpretation, shows only a few areas of low-concentration ice.

The broader and deeper passage through the Canadian Arctic Archipelago, between Lancaster Sound, Parry Channel, and McClure Strait, is still obstructed by ice, but at the end of August ice blocked only a short portion near Victoria Island. Before drawing conclusions about navigability, however, it is important to check with the operational services such as the National Ice Center (NIC) or the Canadian Ice Service (CIS).

Parry Channel now appears more or less open but a complete analysis can't be done as the Canadian ice service doesn't show the entire channel. However, McClure Strait is open but the outer region of the Parry Channel is locally covered with very thin and fragile ice (1-3/10) according to CA.

Parry Channel has finally opened during last week. Mc Clure strait is also open, although ice drift could block it again.

the most recent message from Andros on http://northwestpassage2015.blogspot.co.uk/2015/09/week-10-can-mv-andros-complete.html?view=timeslide   was
20150918-1200 hrs Departing Mercy Bay to attempt a westward Route 1 along the shore through the 2/10 sea ice around Cape Prince Alfred enroute to Sachs Harbour.

Winds are E5 so the ice must be drifting in from the sea current flow.
Outlook for the next 24 hours is E5 but changing Sat night to N5 so we are OK to proceed.

DTG 117 @~6 (dodging ice) = +19 hrs ETA Cape Prince Alfred 20150919-0700 hrs
Sunrise 7:14 MDT
5 POB, all well.

If the sea ice becomes greatly concentrated we will reverse course to the east and escape south in Prince of Wales Strait on Route 2.

There may be no updates for a while since I expect all of us will be busy with ice navigation.

The characterization of this huge adventure as completing the Northwest Passage is being challenged because the eastern end point is neither Greenland nor some point south of the Arctic Circle.

Still a massive accomplishment.

Thanks for the heads up Frank. Interesting indeed!

Global climate models with their coarse resolution likely have difficulty capturing intricate sea ice dynamic processes within the narrow channels of the CAA. Specifically, the import, survival, and thickness of MYI are difficult to predict and may in fact increase during the transition to a sea ice-free Arctic with more mobile ice conditions in the Queen Elizabeth Islands which are located between the Arctic Ocean and NWP.  Presumably, MYI from the Arctic Ocean will be more heavily ridged and thicker than locally formed MYI, posing greater danger to transiting ships than locally grown MYI.

Somewhat earlier than usual, my initial NWP analysis for 2016:

Our coverage of the Northwest Passage is starting somewhat earlier then usual in 2016. That’s because an educational comment of mine seems to have gone permanently missing over at Andrew Montford’s blog.
