Keeping track of dolphins is a slippery, patchy process. First, you must procure time on a ship or aircraft, which is expensive. After that, what you see depends on uncontrollable factors like weather, ocean conditions and whether the creatures happen to be hanging out at the sea’s surface.
"Tracking Dolphins With Algorithms You Might Find on Facebook" is from the December 08, 2017 U.S. section of The New York Times. It was written by Steph Yin and narrated by Mike DelGaudio.
