The IceBridge Gravimeter L3 Bathymetry, Version 1 (IGBTH3) and IceBridge Gravimeter L4 Bathymetry, Version 1 (IGBTH4) data sets (formerly known as IceBridge Sander AIRGrav L3 Bathymetry and IceBridge Sander AIRGrav L4 Bathymetry, respectively), available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), have been updated. In addition to the title change of the data sets due to new gravimeter instruments used for the new data, data from the Venable Ice Shelf, Cook Ice Shelf and Ninnis Glacier Tongue Antarctic areas have been added. These data sets contain bathymetry of Antarctic ice shelves based on measurements from IceBridge Sander AIRGrav L1B Geolocated Free Air Gravity Anomalies (IGGRV1B) and IceBridge LDEO Gravimeter Suite L1B Geolocated Free Air Gravity Anomalies (IGLGS1B). IGBTH4 also includes data for Arctic fjords as well as Antarctic ice shelf areas.
