July 15, 2020 — Scanning the airwaves over Monterey Bay with a hand-held antenna, Stanford University researchers listen for blue whales – or, more precisely, they listen for the suction tags they’ve stuck on blue whales. The first beep sounds and the captain whips the boat on course, following the quickening signal to find the surfacing giant. The three-person crew must reach the animal before it disappears under the ocean, hidden from sight, radar and study for another 10 minutes. [Note: This research was conducted prior to the novel coronavirus pandemic, and has been on hold in accordance with current guidance regarding research operations.]
The crew in this fast-paced chase hails from the lab of Jeremy Goldbogen, assistant professor of biology in the School of Humanities and Sciences at Stanford’s Hopkins Marine Station. In the Monterey Bay and around the world, Goldbogen and his team employ drones, sound-based mapping equipment, and sensor-packed tags to demystify the lives and biology of rorqual whales – large whales that feed by lunging at groups of prey and filtering water through baleen plates. These include humpback, minke, fin and of course blue whales, which at nearly 100-feet long are the largest creatures known to have ever lived.
“The largest animals of all time can’t be in a laboratory in a building, so we’ve been developing technology that pushes the envelope in terms of understanding how animals operate in the open ocean,” said Goldbogen.
