| Zusammenfassung |
| The disappearance of Malaysia Airlines flight MH370 on the morning of
8 March 2014 is one of the great mysteries of our time. Perhaps the most
relevant aspect of this mystery is that not a single piece of debris from the
aircraft was found during the intensive surface search carried out for
roughly 2 months following the crash. Difficulties in the search efforts,
due to the uncertainty of the plane's final impact point and the time that
had passed since the accident, bring the question on how the debris scattered
in an always moving ocean, for which there are multiple data sets that do not
uniquely determine its state. Our approach to this problem is based on the
use of Lagrangian descriptors (LD), a novel mathematical tool coming from
dynamical systems theory that identifies dynamic barriers and coherent
structures governing transport. By combining publicly available information
supplied by different ocean data sources with these mathematical techniques,
we are able to assess the spatio-temporal state of the ocean in the priority
search area at the time of impact and the following weeks. Using this
information we propose a revised search strategy by showing why one might not
have expected to find debris in some large search areas targeted by the
Australian Maritime Safety Authority (AMSA), and determining regions where
one might have expected impact debris to be located, which were not
subjected to any exploration. |
