The Norwegian research vessel called Lance drifting among sea ice floes in the Arctic Ocean.
Looking down over the vessel, while following the coastguard ship in the distance. The ship is travelling along an older ‘lead’ that has been partially frozen over.
Using a hot water drill to cut a hole through sea ice. The snow cover can be seen above the hard sea ice below.
This is a tethered weather balloon that was launched next to Lance and captured data which described atmospheric conditions near to the site.
This is a section through a piece of sea ice, photographed under a large polarising filter, lit from below. The filter brings out the structure, colours and shows the brine channels within the ice.
The ship’s crew used all their skill and experience to release the vessel from the grip of the ice. It took some days but eventually she broke free.
Two scientists walk around Lance using thin canes to stake out areas being studied on the surface of the surrounding sea ice.
A frost coats frozen instruments near to the vessel -scientists must keep them maintained during the drift station.
Looking down towards the deck of Lance from the forward mast. The ship makes slow progress, exploiting weaknesses in the ice floes.
Before the scientific drift station can be established, two of the Norwegian crew go out onto the ice in order to check thickness and stability of the ice, also fixing mooring lines to tie the ship to the ice floe.
