Some “pleasure craft” are currently heading up the west coast of Greenland en route to the Bering Strait via Lancaster Sound and one of the assorted routes through the Canadian Arctic Archipelago. For those of you unfamiliar with the geography of the Northwest Passage, here are couple of hopefully helpful maps:

Whilst there is still ice blocking the route across Baffin Bay from Greenland, the Canadian Ice Service has already started daily coverage of the heart of the southern route through the Northwest Passage. There’s plenty of open water in Lancaster Sound and low concentration sea ice in Prince Regent Inlet:

Further south there is also open water in the Coronation Gulf, but the fast ice between Peel Sound and King William Island has not yet started breaking up:

This slightly cloudy satellite image of the Canadian Arctic Archipelago also shows that the exit of the northern route via McClure Strait into the Beaufort Sea is already navigable:

Facts About the Arctic in June 2024

The JAXA/ViSHOP web site is currently down, so here is the current OSI SAF extent graph for the end of May:

2012’s “June cliff” is almost upon us, and if 2024’s current trajectory continues extent will cross above 2012 for the first time since February in a week or so.

Here’s the GFS model’s current map of snow depth:

Melt ponds are now visible on the ice in the Laptev Sea:

Since a certain “sceptic” has recently been comparing 2024 sea ice extent to “20 years ago”, here’s the current JAXA/ViSHOP extent graph of selected years, including 2004:

The CryoSat-2/SMOS merged Arctic sea ice volume graph finishes on April 15th, but older data is being reanalysed and here is the latest version:

The gap in the near real time data due to the problem with the SMOS satellite during the first half of March has been filled in, but the result doesn’t look very convincing to say the least!

The PIOMAS gridded thickness data for April 2024 is now available. Here’s the end of month volume graph:

Prompted by a comment by Tom in the June open thread, the time has evidently come to open the 2023 Northwest Passage passage thread. First of all let’s get our bearings with the help of this map of the area:

and another map detailing the routes through Canadian Arctic Archipelago that have previously been successfully traversed:

As our starter for ten for 2023, there is already plenty of open water in the Amundsen Gulf, together with plenty of melt ponding on the remaining fast ice in Franklin and Darnley Bays:
