Raw multibeam bathymetry and acoustic backscatter data collected at the Endeavour segment of the Juan de Fuca Ridge during Thompson cruise TN177B (2005, investigator William Chadwick)

The data set was acquired with a ship-based Simrad EM300 multibeam sonar system. The files are in MBSystem format and were generated as part of a project called Continuation Time-Series Responses to a Mid-Ocean Ridge Volcanic Event: Juan de Fuca and Gorda Ridges. Funding was provided with NSF award OCE02-22069.
