[MITgcm-support] bathymetry file in a .bin format

[Martin Losch]

Saeid,

bathymetry for oceans should be < 0, land = 0 (>0 also works). 

There are plenty of examples in the verification folder how to write bathymetry files in matlab (fid = fopen(“bathy.bin”,”b”,”w”); fwrite(fid, bathyField2d, “real*4 or 8”); fclose(fid)), and one in python (verification/seaice_itd/input/gendata.py)
