The most urgent work has already begun as experts announced they had uncovered 300 new artefacts belonging to the expedition.
But time and the elements are stacked against the future survival of Scott's hut and its 8000 items of expedition memorabilia, and it has been declared one of the most endangered sites in the world by the World Monument Fund.
Philippa Foster Back, whose grandfather was part of Scott's 1910 team that helped build the camp, is head of the UK Antarctic Heritage Trust.
"We are in a race against time to preserve this irreplaceable part of our heritage. The end of the fundraising is in sight but the final mile is going to be the hardest," she said.
The fundraising, which has drawn support from around the world, is seeking another $387,000. Half the money has been donated by a private British trust, the February Foundation, with the balance coming from small donors and polar enthusiasts.
It is hoped the work will be finished in time for the centenary celebrations in 2014 when millions will be able to pay a virtual visit to the hut via the internet.
But much work must be done before then. Wind deflectors have been fitted to prevent heavy snow from building up around the prefabricated dwelling and crushing it. Last year 85 tonnes had to be shovelled away from the structure and water from melting ice continues to endanger the interior.
Stoves, lights, clothes, bedding and harnesses for the team of dogs remain where they were left. Objects such as tins, corks, scientific test tubes and compressed "patent" coal bricks from Cardiff remain intact.
Sir David Attenborough, one of the campaign's leading supporters, described the base as "a time warp without parallel. You walk into Scott's hut and you are transported to the year 1912 in a way that is quite impossible anywhere else in the world".
The 15m by 8m hut was built by Scott and his team when they landed in Antarctica in 1911. It took a week to erect but was well-loved by the men who called it home despite the hardships they endured there.
In his journal, Scott observed: "The hut is becoming the most comfortable dwelling-place imaginable. We have made ourselves a truly seductive home, within the walls of which peace, quiet and comfort remain supreme. Such a noble dwelling transcends the word 'hut', and we pause to give it a more fitting title only from lack of the appropriate suggestion."
By the time of his return to the Arctic, Scott had become a hero of Edwardian society and the expedition enjoyed support from the Government and people alike. Schools and churches raised money to buy blankets and tents, and news of their progress was eagerly awaited back home.
Scott recreated the social structures within the quarters that he had known from the navy. A bulkhead of bottled supplies partitioned the living area. Space was set aside for the 16 officers and scientists. The men slept in the wardroom at the east end and dined in the messdeck at the west end.
The wardroom was dominated by a large table and spindle-backed chairs. On Sundays the table was covered with a dark blue cloth, although for ordinary meals it was covered with a white oilcloth.
There was a player piano and an HMV gramophone. At the eastern end a darkroom was built and workbenches constructed for the scientists to conduct their experiments. The men worked hard and gave lectures on their specialised subjects - from watercolour painting to the history of Japan. On feast days such as midwinter's night, they ate roast seal.
Scott's goal was to beat his rival Roald Amundsen to the Pole. He had been greatly disconcerted to learn the Norwegian had changed his plans to conquer the North Pole after a successful American expedition and set sail for Antarctica instead.
In the end Scott, 43, and his party were narrowly beaten to the prize and on the return journey they perished amid scenes of unimaginable suffering.
The explorer's diary dated 29 March 1912 reads: "Had we lived, I should have had a tale to tell of hardihood, endurance and courage ... which would have stirred the hearts of every Englishman. These rough notes and our dead bodies must tell the tale."
