The island is primarily covered in ice and snow, providing a habitat for various species of wildlife, including seals and penguins. The island is often visited by researchers and tourists who are interested in polar exploration and marine biology. Its remote location and pristine environment make it an important site for scientific studies related to climate change and ecosystem dynamics in the Southern Ocean.
