5 When land-based ice such as the Antarctic ice sheet melts, this adds new water to the world’s oceans and thus raises sea level. In contrast, melting of sea ice does not cause sea level rise, just as a melting ice cube in a glass of water does not raise the water level in a glass.

This booklet provides a brief overview of why the U.S. government has stood for decades as the global leader in Antarctic research—and why that investment remains vital to U.S. interests today. We offer it as a resource to policy makers, educators, and all people who are interested in the nation’s role in Antarctica. Find out what makes Antarctica such a uniquely valuable place for investigating our planet and the Universe beyond. Learn what it is like to work in the icy wilderness and how the quest for knowledge links people across borders. Explore how the insights gleaned in this remarkable continent ultimately enrich all of our lives—and why Antarctica matters for our shared future.
