Just a note, mainly as a reminder: We are making JRA the default, but the older forcing options are still available. Those will need to be deprecated via our process (not in this release).

Is this just temporary because of NaNs in the file? If not, then it would be better to set this as a parameter at the top of the module, to make it more explicit. 'default mixed layer depth'

I think this avoids a divide by zero. I assume there are also some science reasons for setting it to 20. I can create a parameter in the code as suggested and will do that later today. I think that's a good idea.

This is a way of avoiding divison by zero. @dabail10 suggested max(c20,work1(i,j,iblk)). I dont have a preference. C20 is set to match the only other fixed setting in subroutine init_coupler_flux.

shouldn't year_init match the new forcing data? maybe it doesn't matter, as long as it's properly set in the -s options. I see below that fyear_init=2005, but I thought that one wasn't used now. It's a little confusing, would be better to be consistent.

I saw this and wondered the same things. I was reluctant to make this change as I didn't understand the importance or history. The other thing is that it will change all the gx3 results as well in our regression test. But I agree 100% that it would be nice if all of this were consistent. Are there other defaults that need to change. Should use_leap_years be always true, for instance? I can make this change as part of this PR, but it will change answers.
