An interesting spin-off

The loss of  Malaysia Airlines Flight MH370 with 239 people is one of the greater aviation mysteries but there is one good thing to come from it - from gCaptain:

MH370 Search Data Unveils Fishing Hotspots, Ancient Geological Movements
Detailed sea-floor maps made during the unsuccessful search for missing Malaysia Airlines Flight MH370, released by Australia on Wednesday, could help increase the knowledge of rich fisheries and the prehistoric movement of the earth’s southern continents.

The Indian Ocean search ended in January after covering a lonely stretch of open water where under-sea mountains larger than Mount Everest rise and a rift valley dotted with subsea volcanoes runs hundreds of kilometers long.

The data that was collected:

...information gathered during painstaking surveys of some 120,000 sq km (46,000 sq miles) of the remote waters west of Australia should provide fishermen, oceanographers and geologists insight into the region in unprecedented detail, said Charitha Pattiaratchi, professor of coastal oceanography at the University of Western Australia.

“There are the locations of seamounts which will attract a lot of international deep sea fishermen to the area,” Pattiaratchi told Reuters by phone.

High-priced fish such as tuna, toothfish, orange roughy, alfonsino and trevally are known to gather near the seamounts, where plankton swirl in the currents in the inhospitable waters.

Pattiaratchi said the location of seamounts would also help model the impact of tsunamis in the region, given undersea mountains help dissipate their destructive energy, and potentially change our understanding of the break-up of the ancient supercontinent of Gondwana.

46,000 sq. miles is about the area of the state of Pennsylvania - a big area to be gathering such crystal clear data. Quite the addition to the world's body of knowledge.

“It is estimated that only 10 to 15 percent of the world’s oceans have been surveyed with the kind of technology used in the search for MH370, making this remote part of the Indian Ocean among the most thoroughly mapped regions of the deep ocean on the planet,” said Stuart Minchin, chief of Geoscience Australia’s environmental geoscience division.
