article_snippet.sent: Dr Duncan began investigating a low-frequency underwater sound signal which was recorded west of Rottnest Island just after 1:30 am UTC on March 8.
article_snippet.sent: the university's Centre for Marine Science and Technology, along with United Nations’ Comprehensive Nuclear-Test-Ban Treaty Organisation (CTBTO) and Geoscience Australia were involved in investigating data that might prove helpful to the search, and originally determined that the noise's source was close to the Maldives and Kudahuvadhoo. '

article_snippet.sent: Dr Duncan Dr Duncan said that the noise may have been due to a geological event, including a small earth tremor, but the timing piqued the interest of Dr Duncan research team. '
article_snippet.sent: It would be more correct to say that his research team has identified an approximate possible location for the origin of a noise that is probably of geological origin, but cannot be ruled out as being connected with the loss of MH370,' Dr Duncan told The Weekend Australian.
highlights_snippet.sent: Curtin University acoustic scientists say Curtin University acoustic scientists recorded 'distinctive' noise from the current search area at the presumed time of the crash .
