Sonar Data

Available through Marine Geoscience Data System

Ted Waitt and the Waitt Institute are pleased to announce the release of all scientific findings from the Institute’s 2009 search for Amelia Earhart in the South Pacific. With the hope that some day the mystery behind the disappearance of Earhart and her navigator, Fred Noonan, can be laid to rest by future explorers putting this data to good use, the Institute is making all sidescan sonar files available for immediate download via the Marine Geoscience Data System (MGDS).

The Marine Geoscience Data System provides free public access to a wide variety of marine geoscience data collected throughout the world’s oceans. MGDS supports data from the National Science Foundation funded Ridge2000 and MARGINS programs, and also affords access to the Antarctic and Southern Ocean Data Synthesis and the Seismic Reflection Field Data Portal. Data may be accessed through text and map-based search interfaces and data visualization/interaction tools, including GeoMapApp and VirtualOcean.

GeoMapApp is a free earth science exploration and visualization application offered for public use by the Marine Geoscience Data System at the Lamont-Doherty Earth Observatory of Columbia University. The application runs in the Windows XP, Windows Vista, Windows 7, Mac OS X (10.4, 10.5, 10.6), Linux and Solaris operating systems using the Java Runtime Environment.


Click here to launch GeoMapApp on your web browser using Java WebStart.

Or, if you prefer, simply download and install the application from the GeoMapApp Home Page. Once the application is active, select the CATALYST 2 imagery from the GeoMapApp menus as shown below:


The main Web page for expedition metadata and data (including full resolution sidescan images and other cruise data as it becomes available in the database) can be found here.
