Answer:
- Comprehend the Antarctic ecosystem
- Comprehend the effects of global climate change on its ecosystem and regions
- Take advantage of the Antarctic region to analyze the upper atmosphere
Explanation:
According to the National Science Foundation, the United States Antarctic Program has three main research goals:
1. Comprehend the Antarctic ecosystem: Antarctica is the less known continent in the world. It is covered in ice and is practically uninhabited by humans. Therefore, groups of scientists travel to Antarctica with the main purpose of carrying out research in order to comprehend this ecosystem along with its unique flora and fauna.
2. Comprehend the effects of global climate change on its ecosystem and regions: Today, climate change and global warming are areas of priority. Antarctica is also suffering from the negative effects of this phenomena. Therefore, it is crucial to comprehend how the Antarctic ecosystem and wildlife will repond to current and future changes and how other regions will be affected by this.
3. Take advantage of the Antarctic region to analyze the upper atmosphere: Although it is extremely difficult to carry out research in this continent, there are three research stations: one located on Ross Island, another at the geographic South Pole, and the last one on Anvers Island. As it is the southernmost continent, an extremely remote region, and practically isolated, researchers have selected it to study the upper atmosphere and space.
