Ice is very useful for experiments. Since Antarctica has so much ice and it costs nothing to maintain it it would seem ideal. The experiments are really classified in two ways: either the scientists want to look at what is in the ice itself (e.g. carbon dioxide content of ice cores) or they want to use the ice as a medium for experiments, most of which are related to cosmic radiation. Select few particles muon are produced on Earth only when neutrinos collide under the ice.
Antarctica.
Aside from researchers working there, there is no permanent human population in Antarctica.
If by 'researchers' you mean 'scientists or those in support of science', the answer is that these people live and work in Antarctica every day of the year. Their assignments, however, are temporary.
There is no indigenous population in Antarctica. Researchers and other residents in Antarctica eat the foods traditional to their own home countries.
What do you think they of course study and do subjects
Antarctica is not the place for experiments, Antarctica is the place for basic research. Research there studies the health of planet Earth.
Food that is cooked for researchers is imported from countries that support the research stations where the researchers work.
Antarctica is the continent with no permanent residents except for researchers. The harsh climate and remote location make it inhospitable for permanent human settlement.
Scientists and researchers in Antarctica live a lifestyle that is supported by their government. This lifestyle includes the import of everything consumed and used and the export of everything wasted and expired. There is no 'sustainability' in Antarctica such as is expected on more productive continents.
So they can get more information about this lonely continent.
yes, there are satellites providing internet access to the researchers.
By International Convention agreements, Antarctica is a military free zone. Soldiers are NOT allowed, except in their capacity as civilian researchers.
