Thanks Etienne,the comparison of the Polarstern Image with the one of the Russian Icebreaker that reached the pole in 2017 is stark.
LOMROG III Expedition reaches the North PoleAugust 22, 2012On board the Swedish icebreaker OdenPosition: 90oN, North PoleWeather: -0.1oC, westerly wind, sunshineDuring a cruise in the Arctic Ocean with the Swedish icebreaker Oden, a Danish-Swedish expedition reached the geographical North Pole on August 22 at 21:43 (UTC), precisely three years after the LOMROG II expedition reached the North Pole. The aim of the expedition is to collect scientific data for the Continental Shelf Project of the Kingdom of Denmark in order to document a claim for an extended continental shelf to the north of Greenland beyond the present 200 nautical mile zone.The North Pole was covered by 10/10 of sea ice and Oden had to break through heavy sea ice, especially during the last few nautical miles. Heavy sea ice was encountered during much of the journey on the way to the North Pole.This was Oden's seventh time at the North Pole and the arrival was celebrated in a very traditional way by raising the flags of all the countries represented on board. After a glass of sparkling wine on the bridge and a group photo on the sea ice in front of Oden, the ship continued its scientific program with a geological coring site close to the North Pole.
LOMONOSOV RIDGE OFF GREENLAND (LOMROG) 2007: CORING AND HIGHRESOLUTION GEOPHYSICAL MAPPINGHowever, it should be noted that in the LOMROG operating area north of Greenland severe sea ice conditions were encountered with 10/10 ice cover and sometimes ~4 m thick multiyear floes.
You can't get any "higher": on 22 August 2011 at exactly 9.42 a.m. the research icebreaker Polarstern of the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association reaches the North Pole. The aim of he current expedition is to document changes in the far north. Thus, the researchers on board are conducting an extensive investigation programme in the water, ice and air at the northernmost point on the Earth. The little sea ice cover makes the route via the pole to the investigation area in the Canadian Arctic possible.
Initial measurements of the ice thickness confirm this: in 2011 as well as in 2007 the most frequently occurring ice thickness was 0.9 metres. As a comparison, the most frequently measured ice thickness in 2001 was around 2 metres.
The Polarstern is at the North Pole for the third time in its history. On 7 September 1991 it was one of the first two conventionally driven ships to sail there, along with the Swedish research icebreaker Oden. Almost exactly ten years later, on 6 September 2001, it carried out a joint expedition at the North Pole together with the American research icebreaker Healy.
Canadian Coast Guard Ship Louis S. ST-Laurent and the Swedish Icebreaker Oden arrived at the North Pole this morning, August 21, 2016, at 1050 hours GMT (0650 hours ET). We found large areas of open water at the Pole, not present in 2015. Later today we hope to get off the ship to celebrate Canada’s fourth visit to 90 degrees North.”

Merged. It becomes the older thread by default.Maybe not a lot of information but I am sure a lot of people interested in this thread.

The white stick holds the top of the thermistor string above the snow/ice surface, so that the temperature profile is measured from approximately 0.5m above the surface and down through the snow, ice and water (Photo: Gorm Dybkjær).

For Norway’s newest icebreaker, it’s (almost) to the pole and backNorway’s most advanced polar-research vessel will end its summer expedition to the Arctic early after thick ice prevented the Kronprins Haakon from reaching the North Pole.Built at a cost of 1.5 billion kroner ($175 million), the Kronprins Haakon entered into service last August. This January, it completed an expedition to Antarctica.After leaving Tromsø on July 3, the third expedition had concentrated on collecting samples from the waters north of Svalbard. It was due to culminate with a sail-over of the North Pole before returning to Tromsø.Making the North Pole was considered feasible for the Kronprins Haakon; it is designed to be able to sail in year-round in ice as thick as two meters and sea trials last year suggested it was capable of sailing in even thicker ice.It reached a latitude of 84° 40′N on July 13, but decided to turn back after meeting first-year ice measuring up to 1.5 meters thick, patches of multi-year ice and little sign of thawing.Despite not reaching the North Pole, the expedition accomplished most of its scientific goals. The ship itself, according to Hans Christian Eilertsen, a biologist with the Universitetet i Tromsø and the expedition’s scientific leader, performed as expected.“Sailing to the North Pole in ice isn’t a walk in the park, even if we’re talking about a big ship. You are always going to have problems, be they technical or logistical,” he said.
