We have never measured so little #SeaIce around #Svalbard #Norway in mid November.

The #OSISAF satellite-based timeseries goes back to the late 1970s.

What an almost pleasant behavior of the global sea-ice extent
- almost reaching the bottom line (=previous minimum extents) from below.

The ocean sector offshore of Queen Maud Land in #Antarctic lacks about 1 million km² of sea-ice cover compared to normal conditions.

The sea-ice extent has been dropping fast the recent days...

Halfway through October 2023, the freeze-up of sea ice is slower (or simply just lower) than normal.

By "normal", is meant the 30-year climatology of the same days in 1981-2010.

The whole thread is worth reading, but the discussion below about #SeaIce datasets and #Osisaf is very interesting for those of us who run and/or use #CimateModels for the #Arctic....

Antarctic sea-ice extent has started to decrease after an extremely low winter maximum. Let's hope for a really slow decrease at least

Today left yesterday (that is Sept 17th) as the "so far" minimum #Arctic #seaice extent for 2023.

A minimum at this stage would result in the sixth-lowest minimum extent on record.

Not record-low, but far lower than most years.

Let's see what tomorrow brings.

For a week, September 12th has marked the date with the largest #Antarctic #seaice extent in 2023.
This is absolutely record-low for an Antarctic maximum extent!

This still can change and we hope it will

Has the #Antarctic #seaice stopped growing in extent this winter?

Negligible differences when calculating latitude in two different ways.

As we approach the annual minimum of #Arctic #seaice extent for 2023, it looks like it will be one of the six lowest on record.

To put it in perspective, the years with lower minimums than this year (in order from lowest to highest) are 2012, 2020, 2007, 2016, and 2019.

Status of the areal coverage of sea ice in #Arctic:
* 3rd lowest in East Siberian Sea (only 2007 and 2012 were lower).
* All "normal" in Laptev Sea.

The graphs show the daily sea-ice extent of 2023 compared with the 1981-2010 baseline and the previous six years 2017-2022.

We are approaching the yearly minimum extent of the #Arctic #Seaice.

It seems that we won't reach a record low this year, but the minimum will still be significantly below the 1981-2010 baseline.

#Antarctic #SeaIce extent was *record low* in August according to #osisaf

We are missing 2 millions km2 of sea ice compared to the 1981-2010 climatology.

The end of winter is approaching in the #Antarctic: soon the Sun will warm the ocean and melt the ice .

Lack of #seaice in the East Siberian Sea.

Sea-ice extent is now closely following the curve from 2012, that landed on record-low ice.

The #Antarctic #seaice growth towards its annual maximum is slow.
Satellite records show the earliest and latest maximum occurred on Aug 28 (2016), and Oct 7 (1997). We're waiting to see how this year compares

The graph shows the daily sea-ice extent in Aug 2023 and previous max extents and their date of occurrence from 1979-2022.
