Read on to learn more about these explorers and the work they do.

Katy Croff Bell: Archaeological Oceanographer

When archaeological secrets lie far below the ocean’s surface, how do historians and archaeologists know where to look? They work hand in hand with archaeological oceanographers like Emerging Explorer Katy Croff Bell.

“I use tools, techniques, and research from oceanography, as well as from my background in geology, to help archaeologists make discoveries,” Croff says.

Currently the Chief Scientist for the E/V Nautilus Exploration Program, abroad Bob Ballard’s exploration vessel the E/V Nautilus, Katy’s work involves searching for shipwrecks and other archaeological hotspots.


Kakani Katija: Bioengineer

Can a tiny ocean organism affect weather around the world? Emerging Explorer Kakani Katija dives into the emerging field of biogenic ocean mixing for answers.

She’s exploring the external power sources that propel the perpetual motion of oceans. Winds and tides have long been known to drive currents circulating within the ocean. But as Katija’s evidence increasingly shows, the movements of swimming animals could have an equally powerful effect.

“My work is just beginning to peel away the outer layer of what might be important to the state of our oceans. We’ve explored only a sliver of our seas. They’re really our final frontier here on Earth,” says Kakani.


Elizabeth Kapu’uwailani Lindsey: Filmmaker/Anthropologist

Elizabeth Kapu’uwailani Lindsey, Ph.D., is the first female National Geographic fellow and the first Polynesian explorer at the National Geographic Society. An award-winning filmmaker and anthropologist, she is committed to ethnographic rescue, the conservation of vanishing indigenous knowledge and tradition.

A descendant of Hawaiian chiefs, English seafarers, and Chinese merchants, Lindsey was raised by native Hawaiian elders who prophesied her role as a steward of ancestral wisdom. Lindsey’s expeditions now take her to some of the most remote regions of the world.
