Readers not added for the following variables: zeta

[brucelaughlin]

Hi,

My ROMS files contain "zeta" as a variable, and I haven't changed anything in "reader_ROMS_native" other than adding a few extra variables to the variable mapping via a wrapper . But I keep getting this in my output:

16:47:53 INFO opendrift.models.basemodel.environment:245: Fallback values will be used for the following variables which have no readers:
16:47:53 INFO opendrift.models.basemodel.environment:248: zeta: 0.000000

and, then at the end:
Readers not added for the following variables:
zeta

I've poked around a bit to try to solve this on my own, but I'm struggling. Any ideas?

Thanks!
Bruce
