North Pole Expedition Overview

The expedition consists of an initial training trip for a couple of days near Longyearbyen, a couple of days making final adjustments and preparations before flying up to Barneo which is the temporary camp in the arctic circle from which expeditions to the Pole set out. Barneo is situated at roughly 89’ North but it shifts about as the ice moves at the Pole. There is no land at the North Pole, just floating ice that is continually moved around by the wind and currents which has two main consequences.

1.      Nothing ever stays in the same place for long in terms of its GPS position – so even when we get to the pole (ie 90’ North) we will not be there for long as the ice we are standing on will soon move off the Pole and drift away from it.

2.      The wind blows and currents move differently over the Pole so various areas of ice are moved at different speeds and in different directions. The pressure builds up and the ice finally breaks apart creating leads and pressure ridges. Leads are where the ice is pulled apart revealing the water beneath the ice – this freezes over time creating new ‘young’ ice. Pressure ridges are where the ice is either blown in different directions or together and when the pressure overcomes the resistance large chunks of ice break off, some of which are pushed upwards and create walls of ice that are generally up to 2m high. There are many of these at the Pole and these need to be circumvented or gone over as is most efficient. In fact, they provide a very welcome break and change from the otherwise very monotonous experience of skiing slowly in a straight line whilst pulling a 20kg sled.

From Barneo, we take a helicopter to get to 89’and start our 60 nautical mile (about 70 normal miles see this Wikipedia link for more info) ski to the pole.  In fact we are almost certain to ski a lot more than that. Given the large number of pressure ridges and leads that we will come across, we will very rarely be able to ski very far in a straight line and so will be zig zagging at best and when things get bad going sideways or even backwards. In addition the wind will be moving the ice that we are on – if we are lucky towards the pole and if not away from it – real mental strength is needed when after a very tough day, you wake up the next morning to find that overnight you have been blown back towards or even past where you started the day before!

 There are three trips running concurrently. Us as the lead ski / manhaul team, another going on dogsleds and a Chinese ski team.
