Line graph time series of 2024's daily Arctic sea ice extent compared to decadal averages from the 1980s to the 2010s. The decadal averages are shown with different colored lines with white for the 1980s, green for the 1990s, blue for the 2000s, and purple for the 2010s. Thin white lines are also shown for each year from 2002 to 2022. 2024 is shown with a thick gold line. There is a long-term decreasing trend in ice extent for every day of the year shown on this graph between January and April by looking at the decadal average line positions.

Monday ice update - #Arctic sea ice extent is currently the 15th lowest on record (JAXA data)

• about 180,000 km² above the 2010s mean
• about 280,000 km² below the 2000s mean
• about 760,000 km² below the 1990s mean
• about 1,180,000 km² below the 1980s mean

We compared our new lead product to other lead products - not straightforward! Because all sensors measure different lead properties, the results can be quite different. We suggest to distinguish between "open-water fraction" and "lead fraction including thin ice".

We derived a time series of lead fractions for the yearlong MOSAiC
drift campaign (2019/2020) showing different phases of high and low lead activity.

We looked at leads of different ages from 0 to 10 days old.

Does that fit with your observations of the sea ice dynamics? - Let us know!

🌊❄️ 💔Curious about wintertime leads in the Arctic sea ice?

➡️ Sea ice dynamics can tell you much more!

🛰️ We have used divergence derived from SAR satellite data to study the presence and formation history of leads.

Where-when-how wide are leads?

Two polar stereographic maps showing Arctic sea ice thickness from CryoSat-2/SMOS and the difference relative to the previous year (October 2022 to 2023).

A first look at the CryoSat-2/SMOS merged product for Arctic sea ice thickness this fall - sea ice is thinner than last year across most of the ice pack
