This is the best summary I could come up with:

All 12 crew members and 227 passengers were presumed dead, and search-and-rescue efforts yielded no signs of the doomed plane apart from a few pieces of debris that washed up on coastal shores months later.

Now, scientists have partially reconstructed the possible origin and drift path of that debris via a novel means: extracting data about ocean temperatures stored in shells of barnacles, according to a new paper published in the journal AGU Advances.

“Knowing the tragic story behind the mystery motivated everyone involved in this project to get the data and have this work published,” said co-author Nasser Al-Qattan, who recently received his PhD from the University of South Florida.

The inspiration for a fresh search strategy struck Gregory Herbert, an evolutionary and conservation biologist at the University of South Florida, a few years ago after seeing photographs of a piece of debris from the downed plane—a flaperon (a control surface designed to control the roll or back of an aircraft and reduce stall speed) found on the beach of an island called Saint-Andre, Reunion, in late July 2015.

The search efforts for MH370 focused on a stretch of several thousand miles along a corridor running north to south, dubbed the "Seventh Arch."

A French biologist named Joseph Poupin was one of the first to examine the flaperon when it was discovered, covered with dead barnacles that were firmly attached with tissue still inside (and smelly, to boot).
