National Geographic Explorer in Residence Enric Sala quit academia to explore and protect the sea. On his journey to keep the ocean pristine, he has swam with jellyfish in Palau, gone diving in the Arctic, and got acquainted with sharks at Millennium Atoll. Sala’s explorations have led to 24 marine preserves—with a combined area more than twice the size of India. But the hard work is far from over, as Sala aims to protect 30 percent of the world’s oceans by 2030.

In 1915 Ernest Shackleton’s ship, Endurance, sank off the coast of Antarctica, stranding the crew on drifting sea ice. Shackleton’s desperate rescue mission saved all 28 men. But for more than a century afterward, the location of Endurance eluded archaeologists—until this year. National Geographic photographer Esther Horvath was there, and recounts the moment when the ship was located 10,000 feet beneath the polar ice.

When India and Pakistan gained their independence from Britain, a border was drawn between the two new countries. The split started a chain reaction of violence that led to one of the largest forced migrations in human history. More than 1 million people died in the tragedy. Both countries are now approaching 75 years of independence, and the people who were there to remember it are reaching their twilight years. This may be our last chance to hear directly from the eyewitnesses who lived through the victory of independence and the subsequent tragedy of partition.

National Geographic Explorer Sparsh Ahuja has been documenting the stories of people who were forced from their homes during partition and is bringing them back to their ancestral home—if not in person then through virtual reality.
