Here are some for loading and interpolating data from BedMachine. You'll have to get the BedMachine data from the NSIDC website (https://nsidc.org/data/idbmg4 for Greenland or https://nsidc.org/data/nsidc-0756 for Antarctica.) Download the full .nc files.
Check the Examples tab above for explanations of how to use these functions.
And as always, if you use this dataset, be sure to cite the Morlighem paper listed below. And if this toolbox is useful for you, please cite my AMT paper listed below.

Tidied up some documentation.
Added grounding lines, coast lines, and bedmachine plotting function. Also changed default output coordinates of bedmachine_data from gridded geo to xy arrays.
Updated for public release of BedMachine Antarctica. Important: Antarctica is now the default option unless northern latitudes are entered, or the 'greenland' option is explicitly given.
