Re the claim posted by jcjeant:
The article refers to a Spiegel story and really has two elements:
MH370: Neue Simulationen stellen Suchstrategie infrage - SPIEGEL ONLINE
The first is the Helmholtz current study.
The second, not noted in the English language writeup, claims that two ocean biologists have identified several of the barnacle species on the debris from photographs. They have previously shown that barnacle species habitat is partitioned by regional climate conditions.
However, their requests for access to some of the specimens for genetic analysis has thus far been ignored.
