The Boeing 777-200ER was carrying 12 crew and 227 passengers. Communication with the aircraft was lost when it was in the vicinity of waypoint IGARI over the South China Sea. Instead of proceeding toward Vietnam en-route to China the aircraft made a turn-back west across the Malay Peninsula; changed direction again and flew north west towards the Andaman Sea; and then turned south. Flight MH370 ended in the southern Indian Ocean.</p> <div class="quote"> <p>After initial air and sea searches, the governments of Malaysia, Australia and the People’s Republic of China agreed that Australia would take the lead in the underwater search operation in the southern Indian Ocean.</p> <p>The Australian Transport Safety Bureau (ATSB) led the underwater search for missing Malaysia Airlines flight MH370 in the southern Indian Ocean, including analysis of the search area, the sea floor mapping and sea floor search.</p> <p>Geoscience Australia provided specialist advice and capability in the sea floor mapping and underwater search and provided an understanding of the environment in which the search was conducted.</p> <p class="margin50"><u>Source</u>: <i>MH370 - Data Release</i>, Geoscience Australia</p> </div> <!-- End quote --> </div> <!-- End Header --> <br /> <div class="row"> <div class="column-left col-width-60"> <h5>Resources</h5> <p>The following resources have been made available by Geoscience Australia:-</p> <ol> <li><p><b>Geoscience Australia</b> website<br /><html><a href="http://www.ga.gov.au" target="_blank">http://www.ga.gov.au </a></html></p></li> <li><p><b>MH370 - Data Release</b><br />This article introduces the work done by Geoscience Australia in support of the ATSB and contains links to multimedia content.<br /><html><a href="http://www.ga.gov.au/about/projects/marine/mh370-data-release" target="_blank">http://www.ga.gov.au/about/projects/marine/mh370-data-release</a></html></p></li> <li><p><b>Story Map</b><br />A multimedia presentation titled <html><a href="https://geoscience-au.maps.arcgis.com/apps/Cascade/index.html?appid=038a72439bfa4d28b3dde81cc6ff3214" target="_blank">The data behind the search for MH370</a></html></p></li> <li><p><b>Bathymetry</b><br />An article which explains Bathymetry - the study and mapping of the sea floor - with links to 3D animations, produced by Geoscience Australia.<br /> <html><a href="http://www.ga.gov.au/scientific-topics/marine/survey-techniques/bathymetry" target="_blank">http://www.ga.gov.au/scientific-topics/marine/survey-techniques/bathymetry</a></html></p></li> <li><p><b>Sidescan sonar</b><br />This article, an explanation of Sidescan sonar, contains a Sidescan sonar image showing a shipwreck located in the MH370 search area, discovered in December 2015<br /> <html><a href="https://www.ga.gov.au/scientific-topics/marine/survey-techniques/sonar/sidescan-sonar" target="_blank">https://www.ga.gov.au/scientific-topics/marine/survey-techniques/sonar/sidescan-sonar</a></html></p></li> </ol> <p>The Report <i>The Operational Search for MH370</i>, by the Australian Transport Safety Bureau, contains many references to analyses performed by Geoscience Australia, and can be downloaded from the page for the External Investigation <html><a href="https://www.atsb.gov.au/publications/investigation_reports/2014/aair/ae-2014-054/" target="_blank">AE-2014-054</a></html> on the ATSB website. </p> </div> <!-- End Column 1 --> <div class="column-right col-width-40"> <div class="MyPanel CommentPanel"> <div class="TextBox CommentBox">Terminology</div> <dl><noglossary> <dt>Bathymetry</dt> <dd>The study and mapping of seafloor topography.
