Log of Jason Dives from cruise TN293 at the Loihi Seamount in March 2013	x component of the location coordinates; location coordinates are based on the nav that the Jason team places before deployment. x, y, z, and heading are all based on the NAV net that Jason personnel deploy prior to the cruise. They convert these to GPS coordinates, but do a reanalysis of nav (re-nav) at the end of the dive. For GPS coordinates, see the virtual van website: http://4dgeo.whoi.edu/webdata/virtualvan/html/VV-tn293/index.html	x
