Her Routine Swim
Nan was swimming off the coast of Rarotonga in late July, accompanied by a research vessel and under the watchful eye of her colleagues. They were tracking her progress by eye and with a drone.
Nan was filming her swim near a small pod of humpback whales with a waterproof camera.
A male humpback whale, perhaps weighing over 23 tonnes and measuring at least 50 feet in length, began swimming toward her as she was shooting.
Nan was well aware that this was not typical conduct.
