      <abstract>The NASA IceBridge Sander AIRGrav L3 Bathymetry (IGBTH3) data set contains bathymetry of Antarctic ice shelves based on measurements from the Sander Geophysics Airborne Inertially Referenced Gravimeter (AIRGrav) system.  The data were collected as part of Operation IceBridge funded aircraft survey campaigns, and are stored in ASCII text format and are available for periodic, ongoing campaigns from 2009 to the present via FTP.</abstract>
