Purpose of your product: Bed/Bathymetry/ice thickness/surface topography of the Antarctic Ice sheet
Geographic region: Antarctica
Upstream
What upstream mask product did you use? Basin definition from Jeremie Mouginot to define grounded vs floating ice (IceBoundaries_Y2014-2016_Antarctica.tif may not be published but is similar to IMBIE's basins), and Rock mask from Antarctic Digital Database (Rock_outcrop_medium_res_polygon.tif)
Reason for using this mask. This mask was the most complete, accurate, highest resolution available at the time when BedMachine was released, and coincided temporally with other datasets.
Effort required by you if upstream product changed (to a community standard). I had to make some minor corrections (grounding line further retreated, etc)
