The #Arctic #SeaIce melt season gains momentum. Look at the stunning break up of the fast ice in Amundsen Gulf and along the Russian coast.

Will the #Antarctic #SeaIce extent drop to a new minimum this year?

Remember, last year was the lowest on record.

This is not a data error, it is a real geophysical anomaly of the climate system.

The #Antarctic #SeaIce extent should be now well above 15 million km².

I agree with @ZLabe's assessment: I don’t know.

Maybe, I could add these sentences to my bot output:

Since satellite measurements began, there has never been so little #SeaIce in the #Antarctic on this day of the year.

That was somehow to be expected. Let's see how long this area stays free of ice. Very interesting season!

By the way, there are plenty open positions at @awi to obtain a PhD. Deadline already mid August. One related to Antarctic sea ice: https://jobs.awi.de/Vacancies/1429/Description/2

Antarctic sea ice concentration from AMSR2 satellite sensor showing the movement and growth of the ice. One area remains open. This is close to the Maud Rise seamount where open ocean polynyas appeared in the past. See e.g. https://doi.org/10.1029/JC092iC03p02819

@awi 's EM-Bird can measure sea ice thickness from a helicopter: today Janna from our group learned to operate the instrument over the Jade Bight (North Sea). Great weather, but sadly, 0 cm sea ice! 😉

Pretty! This is what it would look like over sea ice.

PoLaRobs, to random

It's now a full month since the #Antarctic sea ice minimum this year and still hardly any new ice has formed in the Bellingshausen Sea (lower left in image).
People speculate about when the first "blue ocean event" will occur in the Arctic. In this sector of the Southern Ocean they're already happening.

@PoLaRobs On the other hand, the sea ice in the Amundsen Sea is growing relatively quickly. Maybe I should split this calculation of regional sea ice extent to get a better overview of the Bellingshausen Sea.

Sea-ice thickness or sea ice thickness? I am always struggling with the hyphenation. Please help.

Check out iceberg A23a doing some dancing in the Southern Ocean, probably the last dance. You can find it in the extension of the #Antarctic Peninsula.
