MH370 and trash in the ocean 2

August 16, 2017

The search that just won’t die. Just over three years ago I talked about using satellite imagery to search for debris from the MH-370 crash site. Now, a reanalysis of all imagery available has shown more debris, including some items big enough to be from the aircraft.

Four spots, north of the search area, and well north of the previous debris field

The imagery was obtained two weeks after the crash, and so had been moving at the whim of the wind and the currents. Detailed drift analysis gives some idea of where the debris could have ended up.

Consistent with a crash in the center of the white line, at 35.6°S, 92.8°E

The map doesn’t show tracks, it shows calculated possible final locations, with error bars, from a starting point on the white line, just outside the search area. You will note a dense cluster of them in the vicinity of PH-04, the upper right square. The problem is, of course, that the imagery isn’t good enough to tell what the floating objects are.

Even with Principal Component Analysis image enhancement.

The imagery analysis report can be found here (pdf), and the full file of ATSB reports here.

This new evidence might not be enough to re-start an already expensive search, but it will certainly prompt an intense scrutiny of the sonar recordings from that edge of the search box.
