Compressing Checkpoints in MITgcm Adjoint Computations

Efficient computation of the gradients used for state estimation in the MITgcm general circulation model requires saving intermediate states to disk.  We present some preliminary experiments on compressing these checkpoints in order to reduce the time to read and write checkpoints or to increase the number of checkpoints written to disk.
