Engineers to the Rescue! The Ultrasonic Mission to Save the Ganges River Dolphin
Information, Sugimatsu says, may save the Ganges dolphins from that fate. “We want to understand their migration patterns,” she says. If dolphin advocates know where the marine mammals go in their daily routines and seasonal shifts, they can focus protective efforts in the right areas. What’s more, careful parsing of the dolphins’ clicks can reveal surprising details about their activities, such as the locations where they hunt, play, and nurse young calves. Sugimatsu envisions a day when permanent monitoring stations are scattered along key stretches of the river to keep tabs on the roaming animals. “Eventually, we can issue something like a weather report,” she says.
