- Software:
  The ECCO v4-r4 files were produced using the 'checkpoint66g' versions of the general circulation
   model (MITgcm and ECCO v4 settings), Python analysis package (ECCOv4-py), and Matlab analysis
   toolboxes (gcmfaces and MITprof).
  These software versions are available at http://mitgcm.org/download/other_checkpoints/,
   https://github.com/ECCO-GROUP/ECCOv4-py, and
