Day 6 of my voyage to the #Antarctic Peninsula on the #tallship #BarkEuropa: a close approach to Half Moon Island in McFarlane Strait, South Shetland Islands, but strong winds precluded a landing. Subsequently we approached close to Edinburgh Hill on Livingston Island, a volcanic plug exhibiting spectacular columnar jointing.

Day 5 (continued) of my voyage to the #Antarctic Peninsula on the #tallship #BarkEuropa: second landing, at Whalers' Bay, Deception Island, South Shetland Islands. From the landing site we walked up a valley to a depression in the caldera rim from which Nathaniel B Palmer first sighted the mainland of the Antarctic Peninsula in 1820.

It is currently austral summer, which means that #Antarctic sea-ice extent is on its way to the annual minimum. This year will *not* be a new record low, partially due to very widespread ice cover in the Weddell Sea.

Last month was the 13th lowest #Antarctic sea ice extent on record for the month of January.

This was 510,000 km² below the 1981-2010 January average. Data from https://nsidc.org/data/seaice_index.

Comparison of monthly temperature anomalies in the #Arctic versus the #Antarctic so far in 2025 (yellow lines). The other lines show the monthly anomalies for years from 1940 (blue) to 2024 (red). Note the long-term trends through the color gradient.
