The ship, which Aurora says is build to "world-class" polar standards, will launch in 2021 in Ushuaia, Argentina.
Earle was the first woman to become chief scientist of the US National Oceanic and Atmospheric Administration and was named Time Magazine’s first "Hero for the Planet" in 1998.
Aurora said the ship’s dedication to Earle paid tribute to her efforts to conserve protected marine areas and ocean wildlife. The line has pledged to continue to name its ships after explorers passionate about their commitment to the environment and "share the company’s vision for the future".
