Why do scientists study in Antarctica?

The discovery of Lake Vostok led scientists to ask many questions. How did the lake form? Does anything live in the lake? If so, what lives in the lake? How could living things survive in this environment?To answer these questions, in 1989 scientists began drilling a hole in the ice above the lake. When they got to about 427 feet (130 m) above the surface of the lake, they stopped drilling. They did not want to contaminate the lake. The drilling process used kerosene and antifreeze. Scientists did not want these lubricants to get into the lake.Some research has indicated that microbes exist in the lake. However, other scientists say this research is flawed. They claim no one has been able to get reliable samples from the lake. They state that fluids used in the drilling process have contaminated the samples collected so far. However, scientists do know that Lake Vostok is a freshwater lake. This means that the ocean does not flow into the lake and the lake is an inland lake.
