Explorers are relying on cutting edge technology to map the retreating Arctic ice sheet during a treacherous 1,000km trek to the North Pole.
During the 90-day Catlin Arctic Survey, three seasoned explorers, led by Pen Hadow, will rely heavily on technology for everything from mapping ice levels to relaying their vital signs back to the UK HQ.
During the trek, which began last month, telecoms equipment able to withstand the Arctic's sub-zero temperatures will allow the expedition to relay video streams, live audio commentaries, high definition stills and the explorers' vital signs to the rest of the world.
The Central Data Unit or Onboard Sledge Computer, seen here amid other tech kit, is ruggedised, custom-built equipment, which couples a computer to a multi-modem data uplink system that connects to the Iridium satellite network.
The system transmits data on a live, delayed live or overnight basis.

The article slips in a typical global warming trope - "to map the retreating Arctic ice sheet".
Trouble is the Arctic ice sheet has grown this last year not shrunk as the article states.
Assuming the rest of the article was as inaccurate as the first few lines I did not read further.......
