Black scuba divers across the world were searching for buried shipwrecks from the transatlantic slave trade when millions of enslaved Africans were trafficked to the Americas during the 15th to the 19th centuries. A new six-part podcast series, Into the Depths, follows National Geographic Explorer Tara Roberts as she sets off on the journey of a lifetime to meet the divers, marine archaeologists, descendants of those brought over on ships, and historians investigating the lost stories of the slave trade. She’s inspired to share their accounts to expand the historical record and honor the estimated 1.8 million unsung souls who perished during the Middle Passage. Along the way, Tara meets up with her family and friends, spiritual advisers, and even a poet to help tell those ancestral stories. She delves into her own roots—challenging her assumptions about home and belonging. Join National Geographic Explorer Tara Roberts on a historic journey as she documents some of the thousand slave ships that wrecked in the Atlantic Ocean during the transatlantic slave trade and follow a group of Black divers dedicated to finding and helping document the wrecks. A new six-part podcast series, Into the Depths, and National Geographic Magazine explore the complex history of the global slave trade and the stories of the estimated 12.5-million Africans forced to make the Middle Passage.
