“Phase one involves setting adrift ocean drifter buoys used in the Global Drifter Program along with models of the flaperon which have been fitted with satellite trackers. The models will be tracked to establish the rate and direction of drift relative to the drifter buoys in open ocean conditions when subject to similar winds, currents and waves. Thirty years of real life Global Drifter Program data will then be used to model the drift of the flaperon.”
See Operational UpdateThe part of MH370 that drifted to Madagascar will be used to trace back to the point of impact. This will be a long slow iterative process because of all the variables and the scarcity of drift-data. It could take many years to get a good pattern for the location of impact. Fortunately drifting buoys have been systematically used for decades. Comparing their performance with the part from MH370 could work.
The current search is expected to end in December. The search has been greatly delayed by weather in this stormy part of the ocean. There will be completion of 120000km2 of ocean and closer inspection of a few interesting sonar echos.
