24 April 2018. Numerous ice rings have appeared!


Since several days at least three giant ice rings have appeared:
1 - region of the Cape Nizhneye Izgolovye (exactly where we have observed eddy in February and March, see white circle), ring is not yet fully developed,
2 - region south from the Ol'khonskiye Vorota strait,
3 - near Posol'skiy Sor.
Regions 2 and 3 are unusual, so far there were no ice rings detected in these regions (see map in the Section "On rings").


Coordinates of the rings' centers:
Region 1: 108.375N, 53.5153E, diameter: 6 km
Region 2: 106.8408N, 52.8127E, diameter 8 km
Region 3: 105.96546N, 51.9264E, diameter 5.6 km


Ice conditions from 22 March 2018. No ice ring so far

8 March 2018. Ice ring will probably soon appear. Ice conditions for 6 March 2018.

Anomally warm ice in the region of eddy that was detected earlier.

In the region, where we have found an eddy in mid-February, a high ice temperature is observed. Thermal Landsat image from 6 March 2018. Circle on image - initial position of the eddy (see scheme below)

22 February 2018. An eddy discovered near Nizhneye Izgolovye Cape

During our field works in mid-February 2018 we have discovered under ice a warm anticyclonic eddy, that usually leads to the formation of the giant ice rings.

Eddy is located in 5.8 km from the Nizhneye Izgolovye Cape, its radius is 3.4 km. When travelling on the line of direct sight between Nizhneye Izgolovye cape and Cape Khoboy on Ol'khon island (see the scheme) there is a high risk of getting into the ring. We recommend to keep the direction to Uzury or (better) to Zhima mountain or more to the south.

Many frozen leads are still not very thick, they are seen as red on the thermal image.

Blue - cold (clouds, snow, thick ice), red - warm (thin ice, recently frozen leads)

6 December 2017. Web site is now in two languages - russian and english

End of winter 2017. Ice ring did not manifest on satellite images. Probably it is related to the continuous movement of the eddy


11 April 2017. Eddy has moved! New potential location of ice ring in 2017

Our new field data show that the eddy has moved by 6 km towards the Ol'khon island.

Eddy (and probably future ice ring) is now located 18.5 km from Nizhnee Izgolovye Cape

1 March 2017. Potential location of ice ring in 2017

According to our field measurements in mid-February 2017, we have discovered an underwater eddy, similar to the ones that lead to the formation of giant ice rings

Location of eddy (red circle), one of the existing ice routes between Ust'-Barguzin and Ol'khon island (blue line) and line of direct sight between Cape Khoboy on Ol'khon and Cape Nizhnee Izgolovye (red line). Background image - Landsat, 15 February 2017.


If the eddy will lead to the formation of a giant ice ring, so when using line of direct sight between Nizhnee Izgolovye and Khoboy you will have a 100% garanty to find yourself in the region with dangerous ice cover. We advise to avoid such a route!


Eddy (and probably future ice ring) is located 8.5 km from Nizhnee Izgolovye Cape and 5.5 km north from one of the existing routes to Ol'khon.

23 January 2017. Ice conditions
Ice cover is almost stable, but in many places there are cracks and areas with thin ice. In the southern part ice is still moving
