We’ve been following the voyage of the Canadian icebreaker CCGS Amundsen as he circumnavigated Banks Island. Now Amundsen is about to set off on the final leg of his 2021 Arctic campaign to conduct the “DarkEdge” study in northern Baffin Bay. According to the Amundsen Science web site:
7 October to 3 November – Cambridge Bay to Quebec City
During the final Leg of the 2021 Expedition, an integrated study (DarkEdge) will take place at the ice edge to study the key processes taking place during the fall-winter transition in northern Baffin Bay. The Sentinel North program will deploy an Autonomous Underwater Vehicle (AUV) and contribute to the Dark Edge campaign. The CCGS Amundsen will sail to Quebec City for the end of the annual expedition on November 3rd.
and according to Christian Katlein from the Alfred Wegener Institute:
The Canadian Ice Service daily charts don’t currently cover the north of Baffin Bay, so here’s the most recent weekly which provides some idea of what Amundsen will be facing over the next few weeks:
As Amundsen prepares to begin his voyage to the DarkEdge, here’s a watery sun setting over Cambridge Bay last night:

Here’s the eighth video in Christian’s Sea Ice Stories series and the first from Amundsen itself, whilst moored in Cambridge Bay:

Amundsen has finally located a smidgen of sea ice in Baffin Bay, at approximately 76.10 N, 77.10 W. Click to enlarge:

Amundsen has managed to find some more significant sea ice, this time located at around 76.30 N, 78.70 W:
The time has come to start speculating about if, and when, the Northwest Passage will become navigable for the host of small vessels eager to traverse it this summer. Almost one month later than in 2017!
Whilst the eastern and western entrances to the assorted routes through the Canadian Arctic Archipelaga have been empty of sea ice for quite some time, the central section between Bellot Strait and Gjoa Haven and/or Cambridge Bay is still chock a block:

It’s not entirely clear when that picture was taken, since according to Michał’s blog:
The waters beyond the Bellot Strait are covered with impassable ice, and the ice in the Beaufort Sea has 90% concentration in some places and reaches up to the shore. In this difficult situation, by 15th August two yachts have already given up and turned back to Greenland (including Blue Peter from our cove).
Here’s what lies ahead of Crystal and her remaining companions, according to the Canadian Ice Service:
Meanwhile in the Beaufort Sea S/V Dogbark has been battling her way through that “90% concentration” sea ice. Dogbark has now made it as far as Mikkelsen Bay, just past Prudhoe Bay in Alaska:
What does 7/10ths ice mean? We don’t want to know! It is more ice than we want to try and pass, that’s for sure. But the ice charts we look at refer to ice by % of sea coverage, so 7/10ths would look like water mostly covered by large, immovable objects. 5/10ths was as much as we have seen, and we got out of there as fast as we could with some help from our flying eyeball. See Dogbark’s Facebook page for a quick snippet of less dangerous ice.
Meanwhile the Canadian icebreaker CCGS Amundsen has sailed past Arctic Bay and Resolute:
I cannot help but wonder what vessels might be closely following in his wake?

Finally there comes news that a “pleasure craft” has made it through the Canadian Arctic Archipelago from east to west as far as Tuktoyaktuk. I’d been wondering which vessel it was that seemed immobile near the western end of the Bellot Strait on the MarineTraffic maps. This one’s from August 19th:
Now I know! Thanks to a heads up on the Arctic Sea Ice Forum I’ve discovered that it’s the S/V Thor. Here’s the tracking map of his efforts to get through all the old ice in the vicinty.
The map reveals that Thor made it through the Bellot Strait on August 6th, but didn’t manage to make significant headway out of the Franklin Strait until August 28th.
The time has come to start speculating about if, and when, the Northwest Passage will become navigable for the host of small vessels eager to traverse it this summer. The west and east entrances are clearing early this year. Lancaster Sound and Prince Regent inlet already reveal only a few area of white amongst the deep blue open water:

To the west the route is already opening up all the way from the Chukchi Sea to Cambridge Bay:

The problems on the southern route seem likely to arise in the central section this year, where far more old ice is present this year than in 2016:
The remaining sea ice in Queen Maud Gulf doesn’t look like it will last long, but the ice in Victoria Strait and Larsen Sound is made of much sterner stuff:

The cruise liner Crystal Serenity is anticipating navigating those waters once again this year, on August 29th. However much smaller craft are already heading for the Northwest Passage. Celebrate and Alkahest are already sailing north along the west coast of Greenland. Meanwhile Yvan Bourgnon is due to depart Nome, Alaska tomorrow, sailing his catamaran single handed in the opposite direction.
The crew of the Coast Guard Cutter Maple, a 225-foot seagoing buoy tender home ported in Sitka, Alaska, departed [July 12th] on a historic voyage through the Northwest Passage.
This summer marks the 60th anniversary of the three Coast Guard cutters and one Canadian ship that convoyed through the Northwest Passage. The crews of the U.S. Coast Guard Cutters Storis, SPAR and Bramble, along with the crew of the Canadian ice breaker HMCS Labrador, charted, recorded water depths and installed aids to navigation for future shipping lanes from May to September of 1957. All four crews became the first deep-draft ships to sail through the Northwest Passage, which are several passageways through the complex archipelago of the Canadian Arctic.
The crew of the cutter Maple will make a brief logistics stop in Nome, Alaska, to embark an ice navigator on its way to support marine science and scientific research near the Arctic Circle. The cutter will serve as a ship of opportunity to conduct scientific research in support of the Scripps Institution of Oceanography.
The Maple crew will deploy three sonographic buoys that are used to record acoustic sounds of marine mammals. A principal investigator with the University of San Diego embarked aboard the cutter will analyze the data retrieved from the buoys.
The Canadian Coast Guard Ship Sir Wilfrid Laurier will rendezvous with the Maple later this month to provide icebreaking services as the Maple makes it way toward Victoria Strait, Canada. The Maple has a reinforced hull that provides it with limited ice breaking capabilities similar to Coast Guard 225-foot cutters operating on the Great Lakes.
There doesn’t seem to be any up to date tracking information for the Maple, but CCGS Sir Wilfrid Laurier has recently arrived off Utqiaġvik (Barrow as was):

Another article by Chris Mooney in the Washington Post includes this image of the eastern entrance to Bellot Strait on August 11th:
According to Chris:
After we’d passed through safely, Claude Lafrance, the ship’s commanding officer, took some time to explain how the strait worked with the help of a navigational chart. In the process, he lent credence to some of the observations made by Larsen over 70 years ago, while also explaining how modern knowledge has made navigating it safe with a proper tidal understanding.
The essence is that depending on when you are in Bellot Strait, the waters can be flowing either westward or eastward at and around high or low tide, respectively. So timing your crossing makes a great deal of difference.
The danger is that if you’re coming from the west (as we were) with the current to your back, you can be moving too fast, and have difficulty steering your vessel as you approach rocks at the end of the strait.
“We always want to go through where it’s more difficult, with the current against you, because it’s a lot easier to control the movement of your ship,” Lafrance said.
Therefore, the two-hour wait was quite intentional: The CCGS Amundsen stayed put until the tide began to shift and the waters to flow back westward, in effect neutralizing the current. Then the ship steamed out easily. “We just passed at the ideal time to go through,” Lafrance said.
Here’s Sentinel 2A’s view of what he should expect to see in Larsen Sound after emerging at the other end:

From the C3 expedition, also in the Franklin Strait area by the look of things:
Yesterday, we broke through ice that was two metres thick. Thank you to the Canadian Ice Service for ensuring our safe passage! #CanadaC3pic.twitter.com/2nCgalwPOo
The latest CIS ice chart reveals a circuitous route via McClintock Channel that is ALMOST <= 6/10 concentration. Meanwhile Larsen Sound is still refusing to open up for the imminent arrival of the Crystal Serenity:
[Edit – August 27th]
At long last the CIS concentration map reveals a <= 6/10 concentration path along the entire southern route via Bellot Strait:
[Edit – August 29th]
It is now possible to squeeze through Roald Amundsen’s route through the Northwest Passage without encountering over 6/10 concentration sea ice:
David Scott Cowper sought shelter for Polar Bound in the welcoming arms of Booth Island for a couple of days. Now they’re off again and have taken another close look at Cape Bathurst, but which route will they take now?
[Edit – September 10th]
David Scott Cowper has left Cambridge Bay in Polar Bound and is heading east:
here’s what lies ahead of him:
