Hi Clarie,
The entire global LLC4320 (corresponding to your "2km" case) grid info 
is here:
ftp://ecco.jpl.nasa.gov/ECCO2/LLC4320/grid/
especially "readme"
ftp://ecco.jpl.nasa.gov/ECCO2/LLC4320/grid/readme.txt
You can extract the regional domain of your interest from the global one.
Please let us know if you need more help.

cheers
