[MITgcm-support] masking basins

[Christoph Voelker]

Hi Manfredi,

as Ryan said: it depends on your grid and it can be a pain. But: There
is one resource that can ease the pain quite a bit: For the Word Ocean
Atlas there exists a file that gives each point on the WOA grid (i.e.
1x1 degree in the horizontal, 33 levels in depth) a code for in which
basin it is in. The code runs from 1 to 58 and includes even codes for a
number or marginal seas, like mediterranean, sulu sea, ... Based on that
I have constructed myself a ocean basin mask for my grid quite easily.

I had downloaded that file (it is called oceanbasins.nc) once, but have
forgotten where from exactly. But it was one of the WAO pages, maybe
here: http://www.nodc.noaa.gov/OC5/WOA05/woa05nc.html
If you have difficulties in locating it, I can also make my file
available on our local non-permanent ftp site (it is too large for
attaching, especially for this mailing list).

Cheers, Christoph
