Raw multibeam bathymetry and acoustic backscatter data collected at the East Lau spreading center during Langseth cruise MGL0903 (2009, investigator Robert Dunn)

The data set was acquired with a ship-based Simrad EM122 multibeam sonar system. The files are in MBSystem format and were generated as part of a project called Crustal Accretion and Mantle Processes Along the Subduction-Influenced East Lau Spreading Center. Funding was provided with NSF award OCE04-26428.
