[MITgcm-support] ini_phiref warning

[samar khatiwala]

Hello

After a long hiatus, I recently upgraded to a more recent version of the
model. Running the model now generates the following warning:

INI_PHIREF: Unable to compute reference stratification
INI_PHIREF:  with EOS="POLY3" ; set dBdrRef(1:Nr) to zeros

What is the reason for this warning and is it something I should be
worried about?

Thanks, Samar
