CSV IceBridge topography data from Petty et al., 2016, TC.

CSV versions of the 20 cm threshold ridge height data hosted at https://zenodo.org/record/51569 which were stored as Python 2 pickle files. This caused issues as they are not simply loadable with Python 3. Alternatively, to read the Python 2 pickle files you can use the following: https://rebeccabilbro.github.io/convert-py2-pickles-to-py3/

Original data used to assess Arctic sea ice topography using high-resolution IceBridge laser (ATM) data, from the following publication:
