“They’re practically seeding the higher areas of the ocean with The chance for flora to mature,” veteran marine ecologist Ari Friedlaender stated although bobbing with a Zodiac raft off the Antarctic Peninsula.

The team interacted with dozens of whales about the system of four times in Antarctica. They employed specialized digicam drones to measure system dimensions and suction-cupped tags slapped onto the animals’ backs with a very long pole to document the way they go whilst capturing whale’s-eye-perspective movie.
“And tripscan that’s what feeds the food items for whales, birds, seals — almost everything. They’re essentially farmers recycling nutrients and there’s extra foods accessible to them the more they’re around.”
