Alaskan Muck: Windy Dome Ice Core

The ice in Franz Josef Land [also] only dates back to the Heinsohn Horizon.

Graham Bell Island is the most easterly island of the Franz Josef Archipelago.

Franz Josef Land … is a Russian archipelago … inhabited only by military personnel … consists of 192 islands …,

Graham Bell Island is well known for :

It’s Cold War airfield …

In 1993, the airfield was abandoned, and in 2013 during the work on “Clearing the Arctic” it was practically destroyed, only a few scattered elements of the airfield infrastructure remained: RSP, UPC, radar antenna, etc.

Graham-Bell Island –

Greem Bell is an airfield of the Russian Air Force in Arkhangelsk Oblast, Russia.

It is located on Graham Bell Island in the Franz Josef Archipelago, 1372 km north of Khatanga, and is the northernmost airfield in Russia, at latitude 81°N.

It is an ice airfield operational only during the winter months, roughly from the end of November to the beginning of March, and uses the internal callsign XLDG. Greem Bell Airfield was shut down in 1994, but re-opened in 2012.

It’s strange land surface …

And it’s 509 metre high ice dome.

The highest point of Graham Bell Island, 509 m (1,670 ft), is the summit of Kupol Vetrenyy (Купол Ветреный) “Windy Dome“, a large ice dome covering the western part of the island.

An ice dome is a part of an ice cap or ice sheet that is characterized by upstanding ice surface located in the accumulation zone. Ice domes are nearly symmetrical, with a convex or parabolic surface shape.

They tend to develop evenly over a land mass that may be either a topographic height or a depression—often reflecting the sub-glacial topography.

In ice sheets, domes may reach a thickness that may exceed 3,000 m. However, in ice caps, the thickness of the dome is much smaller; measuring roughly up to several hundred metres in comparison.

Radio echo sounding indicates the ice is between 425 and 450 metres deep.

In 1997 a 315 metre ice core was extracted from the Windy Dome ice.

A 315-meter ice core obtained in April-May, 1997 from the summit of Windy Dome, Franz Josef Land in the Russian high Arctic (81°N, 64°E, 509 masl) reflects 772 years of climate variability in the Barents Sea region.

The Windy Dome chronology indicates ice began accumulating around 912 CE.

Very good quality core was extracted throughout the uppermost 175 m of ice drilling.

Increased fracturing was seen in the lower portion of the 315 m core

This dating appears to be very consistent around the Arctic.

Age of Ground Ice

In the area studied by the writer an age of 500 to 1,000 years is indicated.

Ernest de Koven Leffingwell – 1919
United States Geological Survey – Professional Paper 109


Projecting the Colle Gnifetti trend line down to 3,000 metres suggests the bottom ice in the GRIP ice core is about 1,200 years old.

The Libby alignment suggests the Greenland Ice Sheet is about 1,100 years old
i.e. exactly the same age as the ice on Iceland.


The recalibration of the 2017 Alaskan muck assemblage adjusts the original range of 8,000-50,000 years BP down to 520-975 years BP aka 1430-975 CE.


The results from Hofsjökull suggest the ice is somewhere in the region of 1,100 years old.


Mendenhall forest was smothered in ice sometime after 800 CE.

    Neat and slick again Tim!
    I loved the full GRIP diagrams in one photo.


    Just for History’ sake when it comes to sudden changes in climate
    when there were no cars and coal or diesel boats, here’s a piece:


    “A considerable change of climate, inexplicable at present to us, must have taken place in the Circumpolar Regions, by which the severity of the cold that has for centuries past enclosed the seas in the high northern latitudes in an impenetrable barrier of ice has been, during the last two years, greatly abated . . . 2000 square leagues of ice with which the Greenland Seas between the latitudes of 74° and 80° N have been hitherto covered, has in the last two years, entirely disappeared . . .

    The floods, which have the whole summer inundated all those parts of Germany where rivers have their sources in snowy mountains, afford ample proof that new sources of warmth have been opened . . .”

    Extracts from a letter by the President of the Royal Society to the British Admiralty, recommending they send a ship to the Arctic to investigate the dramatic ice reduction — in 1817.

    Thank you (a lot), Yry

    Following those links led me to here, amonst other places. Recently i noticed that on nullschool there were two areas of particularly cold ocean, -2C, one more or less above Gakel ridge north of F.J.L. and the other above the crater/caldera? at the Laptev end of the ridge. The one north of F.J.L. is there at present, others come and go along the ridge.,82.60,630/loc=62.269,85.568 I’m assuming something takes heat from the ocean as it evaporates.
