The charity, East Anglia's Children's Hospices is to benefit from money raised by crew members of a Royal Navy Ice Patrol Ship.
20 members of HMS Protector's Ship's Company have taken part in the event to raise money for the charity.
Dressed as Santa Claus, with one Rudolph, they took part in a run on the ice around Deception Island in the Antarctic.
