Glaciologists have called the Thwaites Glacier the "most important" glacier in the world, the "most risky" glacier and even the "apocalyptic" glacier.
Scientists from Great Britain and the USA are studying changes in glaciers as part of the Thwaites Glacier International Collaboration.
BBC chief environmental correspondent Justin Rowlatt visited the project.
"Snotsicle" - clearly unattractive amounts of frozen mucus - are just a few of the challenges facing science in a place as extreme as Antarctica.
Scientists fear a catastrophic collapse of the Thwaites glacier.
West Antarctic ice has a potential sea level rise of more than three meters, enough to flood many large cities around the world and drive hundreds of millions of people out of their homes.
The BBC's main environmental correspondent, Justin Rowlatt, has traveled with a team of scientists who are part of a US $ 50 million (£ 38 million) joint project between the United States and the United Kingdom.

According to recent avant-garde tests, Takabuti, an Egyptian mummy that has been in the Ulster Museum since 1835, appears to have been killed by stab wounds in the back.
In addition, scientists believe that she can't even be Egyptian, since DNA tests have shown that she is genetically more similar to Europeans than modern Egyptians.
The results will be published on the 185th anniversary of their unpacking.
Actress Marion Cotillard traveled to Antarctica with Greenpeace to find out how climate change, plastic waste and industrial fishing are harming wildlife.
"As virgin as it sounds, even a remote place like this is affected by harmful human activities," he said.
During his trip he spoke to the Victoria Derbyshire program about the "big" environmental problem of the film industry.

At the World Economic Forum in Davos, Switzerland, he asked politicians and business leaders what added value added wealth was "if there was nothing you could do but watch the fire burn".
Charles used his speech to launch a new sustainable market initiative, a project designed to encourage the private sector to become more environmentally friendly.
