pyberg, a simple iceberg drift and decay model in Python

Routines and notebooks for computing iceberg trajectories and melting offline

• so far supports reading (interpolated) forcing data from the COSMOS climate model and AWI-CM
• code is based on the Fortran code of FESOM-IB

The Fortran source can be found here, after registration at swrepo1.awi.de.
