JAXA ARCTIC SEA ICE EXTENT:  9,239,003 KM2 as at 30-Jun-2023

- Extent loss on this day 102k, 22 k more than the average loss on this day (of the last 10 years) of 80k,
- Extent loss from maximum on this date is 4,885 k, which is 144 k, 2.9% less than the 10 year average of 5,029 k.

- Extent is 11th lowest in the 44 year satellite record.

- Extent is  46 k MORE than 2022,
- Extent is  202 k MORE than 2021,
- Extent is  320 k MORE than 2020,
- Extent is  203 k MORE than  2019,
- Extent is  265 k MORE than 2016
- Extent is  199 k MORE than 2012
- Extent is  82 k MORE than the 2010's Average
_____________________________________________
On average 51.1% of extent losses from maximum to minimum done, and on average 76 days to minimum

Projections. (Table JAXA-Arc1)

Average remaining extent loss (of the last 10 years) would produce a minimum in September 2023 of 4.42 million km2, 1.25 million km2 above the Sept 2012 record low minimum of 3.18 million km2, and 8th lowest in the satellite record

JAXA ARCTIC SEA ICE EXTENT: Another month gone so here is a look at June data.

The June 2023 monthly average sea ice extent was 10.41 million km2, 12th lowest in the 45 year satellite record, 0.46 million km2 above the longterm linear trend, and 0.14 million km2 below the June 2022 average.

If daily sea ice extemt gains and losses are at the average of the last 10 years for the remaining 6 months of the year, 2023 daily average extent for the year will be 10.08 million km2, 9th lowest in the 45 year satellite record, 0.34 million km2 above the longterm linear trend, and 0.11 million km2 below the 2022 average.

[gerontocrat]

JAXA ARCTIC SEA ICE EXTENT:

The 365 day trailing average in June rose by the small amount of 12k km2 to 10.121 million km2, 0.447 million km2 above the longterm linear trend, and 0.487 million km2 above the record low in March 2021.

Average sea ice extent loses and gains from now would see a small reduction by the end of the year but then followed by increases in 2024.

June 2023 was yet another month of below average sea ice loss

NSIDC  ARCTIC SEA ICE AREA (5-day trailing average):  7,582,018 KM2 as at 30-Jun-2023

- Area loss on this day 108k, 12 k more than the average loss on this day (of the last 10 years) of 96k,
- Area loss from maximum on this date is 5,351 k, which is 320 k, 5.6% less than the 10 year average of 5,672 k.

- Area is at position #12 in the satellite record (#1=lowest),

- Area is  378 k MORE than 2022,
- Area is  447 k MORE than 2020,
- Area is  460 k MORE than 2016

_____________________________________________
On average 57.1% of Area losses  from maximum to minimum done, and 72 days to minimum

Projections.

Average remaining Area loss (of the last 10 years) would produce a minimum in Sept 2023 of 3.32 million km2, 1.07 million km2 above the Sept 2012 record low maximum of 2.25 million km2, and 14th lowest in the 45 year satellite record.

The contrast continues between
- slow sea ice area losses in the High Arctic with high sea ice concentration, and
- reasonably fast sea ice area losses in the Peripheral Seas with low sea ice concentration.

NSIDC  ARCTIC SEA ICE AREA (5-day): some more

Graphs to show state of play in the peripheral regions attached. (1 of 2 posts).

Okhotsk and Bering - melt basically finished.
Hudson Bay - still on track for an early finish.

NSIDC  ARCTIC SEA ICE AREA: some more

Graphs to show state of play in the peripheral regions attached. (2nd of 2 posts).

St. Lawrence - July mask change will end it.
Baffin Bay - melt on track at a bit above the 2010's average. No reason not to expect almost total meltout.
Greenland Sea - Warmth (ocean and air) triumphs over Fram ice export in the end. Daily sea ice area losses currently well above average, with sea ice area now close to the 2010's average. The Greenland sea ice area at minimum is usually the main determinant of the peripheral seas minimum.
Barents - almost done with a late melt flourish. July change should see sea ice area at almost zero.

Another century drop today. JAXA has lost almost 800,000 km2 in the last 7 days, and 1,070,000 km2 in the last 11 days.

- Extent loss from maximum on this date is 4,984 k, which is 143 k, 2.8% less than the 10 year average of 5,126 k.

Another century drop today. JAXA has lost almost 800,000 km2 in the last 7 days, and 1,070,000 km2 in the last 11 days.

For the first time since late May the 7 day average of sea ice extent daily change has dropped well below the 10 year average.

Interestingly, we are entering the 3 week period when it looked like 2020 sea ice extent was going to make a serious challenge to the 2012 record low minimum.

NSIDC ARCTIC SEA ICE AREA (5-day trailing average data): Another month gone so here is a look at June data.

The June 2023 monthly average sea ice area was 8.90 million km2, 12th lowest in the 45 year satellite record, 0.45 million km2 above the longterm linear trend, and 0.05 million km2 above the June 2022 average.

If daily sea ice area gains and losses are at the average of the last 10 years for the remaining 6 months of the year, 2023 daily average area for the year will be 8.92 million km2, 13th lowest in the 45 year satellite record, 0.40 million km2 above the longterm linear trend, and 0.00 million km2 below (i.e. equal to) the 2022 average.

[gerontocrat]

NSIDC ARCTIC SEA ICE AREA (5-day trailing average data):

The 365 day trailing average in June rose by a marginal amount of 5k km2 to 8.891 million km2, 0.40 million km2 above the longterm linear trend, and 0.69 million km2 above the record low in February 2021.

Average sea ice area losses and gains from now would see no reduction the average by the end of the year then followed by small increases in the first half of 2024.

[gerontocrat]

NSIDC  ARCTIC SEA ICE AREA (5-day trailing average):  7,469,920 KM2 as at 01-Jul-2023

I hope Juan is ok - he didn't post yesterday and he is already late today.

Anyway, the figures for 2nd June are 9,045,817 km2, a drop of 94,139 km2

https://ads.nipr.ac.jp/vishop/#/extent

The weather situation is mostly unchanged from Saturday to Saturday, except for a very interesting hot air intrusion from Canada reaching the Pole in a few days (of forecasts hold). So expect similar drops in extent the next few days ...

Thank you for your posts, binntho. I am traveling with my family. We haven't been all together since 2019, so I am great  . Sometimes is difficult to make the post day after day. Anyway, I will be with them all this week (in case I miss another post).
Have a great day all of you!!!

No NSIDC data for 3rd July.

If NSIDC keeps on updating so late I guess I will have to start posting data from 2 days ago instead of one day.

NSIDC  ARCTIC SEA ICE AREA (5-day trailing average):

Sea ice melt in the High Arctic has picked up, mostly due to strong sea ice area losses in NSIDC's Central Arctic region. (see graph and table attached).

Sea ice area loss in the Peripheral Seas has slowed down a little bit.

NSIDC  ARCTIC SEA ICE AREA (5-day trailing average): A bit more

High Arctic sea ice area continues to fall a bit above average though still a above 2022 and the 2010's average.

Losses are more generally dispersed among the various regions ( see table) and Central Arctic sea ice area losses have moderated.

Peripheral Seas sea ice area losses continue on their way to perhaps a low but not extremely low minimum.

[be cause]

I don't recall 5 days in a row  over 100k last year in the High Arctic , but this is likely in part meltponds . But those that fool sensors are v. likely to melt out anyway . It looks very like 2023 will take the lead over 2016 on your graph in the next few days . Dull this season is not ! But where will this collapse in area end ?

 p.s looking at the graph again I see that the high melt in the CAB was when the dark melt ponds appeared . The same is true for the East Siberian Sea .
