Quick Summary

The Ronne Antarctic Research Expedition (RARE) was a United States project led by Finn Ronne in 1947–48. Ronne, a Norwegian-born American explorer, had previously participated in two of Admiral Richard E. Byrd's Antarctic expeditions. The RARE expedition utilized the former U.S. Antarctic Service East Base camp on Marguerite Bay. This expedition, along with others from the U.S. around the same time, raised concerns among nations with territorial claims in Antarctica, such as Britain, Argentina, and Chile, about the potential for the United States to reassert its own claims. Edith Ronne, Finn Ronne's wife, and Jenny Darlington were part of this expedition, marking the first time women researchers participated in polar exploration.12
