...but they did not find the wreckage of Amelia Earhart's plane. Here's a summary article:
https://www.nytimes.com/2019/10/14/science/amelia-earhart-robert-ballard.html.

From the article:
"Robert Ballard, the ocean explorer famous for locating the wreck of the Titanic, led a team aboard the resesearch vessel Nautilus that discovered two hats in the depths. It found debris from an old shipwreck. It even spotted a soda can. What it did not find was a single piece of the Lockheed Electra airplane flown in 1937 by Amelia Earhart and Fred Noonan, which vanished during their doomed voyage around the world. Dr. Ballard and his crew don’t consider it a failure. For one thing, he says, they know where the plane isn’t. And in the process, they may have dispensed with one clue that has driven years of speculation"

And later: 
"Each time a new search tactic yielded nothing, Dr. Ballard said, he felt he was adding 'nail after nail after nail' to the coffin of the Nikumaroro hypothesis."

Apparently, the (light) documentary on this latest expedition will air on Sunday (20 Oct 2019) on the National Geographic Channel. There is a preview here.
