The Laptev and East Siberian Seas have now refrozen. Consequently Arctic sea ice extent is now increasing more slowly, and JAXA/ViSHOP extent is 3rd lowest for the date in the satellite era:
Introducing the third dimension, here’s the PIOMAS gridded thickness data for the end of October 2024:
Note the change in scale from previous months, to allow for easier comparison with the “near real time” CryoSat-2/SMOS merged thickness data from the Alfred Wegener Institute:
On October 31st Arctic sea ice volume had increased to 6.33 thousand km³, 2nd lowest for the date in the PIOMAS record:
CryoSat-2/SMOS volume is also currently 2nd lowest for the date, although likely to be revised upwards slightly when the reanalysed data is released in a few weeks time:
DMI modelled Arctic sea ice volume is still lowest for the date in the satellite era. Here’s the latest daily graph:
Plus the monthly graph for October:
Finally, for the moment at least, here is the map of sea ice age at the beginning of October:
