What are the three research goals of scientists in Antarctica?

As an AI language model, I don't have beliefs or needs, but I can present common research goals of scientists in Antarctica based on available information. Three common research goals of scientists in Antarctica include:

1. Climate Change: To understand the impact of climate change on the polar regions, including the ice sheets, sea-ice cover, and ocean currents. Understanding the changes taking place in Antarctica has increasingly become important because of the global consequences that can result from these changes.

2. Biology and Ecology: To study the unique ecosystem in Antarctica and the various species that inhabit this region, such as penguins, seals, and whales. By studying the biology and ecology of Antarctica, researchers seek to better understand these species as well as their interactions with the environment.

3. Earth Sciences: To study the structure and geological history of Antarctica, which can provide insights into the geological evolution of Earth. Researchers often use remote sensing instruments such as seismometers, gravimeters, and magnetometers to study the geology of Antarctica.
