The sound of a locomotive in the middle of the Arctic

In the last few days we have been getting messages from Mark Drinkwater from ESA to veer to a radical  easterly direction instead of going straight North to the pole.
Apparently spring has arrived in the Arctic somewhere in the 7 million square km and the ice is starting to break up as it transport  ice from the Arctic into the Fram Straight between Greenland and Svalbard.
The last days the wind has been hauling 12 knots or more from the east blowing us to the west.
Before that is was blowing from the west and transporting us to the East.

The wind shifts around the pole and we are governed by its randomness.
According to Mark if we get into the critical low east coordinates we may get caught in a southerly drift, and have difficulty reaching the pole.
All this wind shifting in combination with the current makes the Arctic sea ice suddenly mobile.

The temperatures are still cold -25C with windchill but today for the first time we see that spring has arrived.
Wind doesn’t do much for freezing leads but a shift of 10 degrees does.

Within minutes after leaving our tent this morning, we passed over previously frozen cracks now filled with water.
Brand new pressure ridges are formed and today we watched two plates collide minutes after passing through.

With all this comes the sound: some have described it as squeaky styrofoam or a pressure cooker going off, a diesel locomotive coming to a screaming halt.

The sound of moving ice, its force, the power of all this mass put into motion at once is amazing and terrifying.
We will see open water in the next days, the first signs are here.
Temperature is going up and the Arctic will react.

So far the trek has been easy but it could very well be possible that our last 70 km to the Pole may the be most challenging.
