Livestream Natural Science: Hunting with the Ocean's Giants

Although whales are the largest animals ever to exist on Earth, researchers spent decades limited to studying them in the few seconds the animals surface for air. Drones and suction-cup-mounted measuring equipment have changed that - now science can follow whales deep into the ocean.

Professor Peter Teglberg Madsen from the Department of Biology at Aarhus University presents what this new technology reveals: the hunting technique of porpoises in Danish waters, the sperm whale's food search more than 1,000 meters down, the Greenland whale's survival in Disko Bay, and the remarkable fact that a humpback whale mother can nurse her calf for half a year without eating herself. The lecture concludes with the question of what sustainable coexistence with these apex predators requires of us.

Madsen is a world-leading researcher in whales' and bats' use of biosonar. The lecture is part of the Public Lectures in Natural Science series from Aarhus University and is livestreamed from the Sea Auditoriums in University Park. It typically lasts two hours with a 20-minute break and a question session where the audience can submit questions via SMS. Free admission. Location: The large pink room on the 1st floor (Activity Room 3) at Nørrebro Library.
