Hi Chris,
I have two groups (Cyanobacteria, using stokes migration) and (F-diatoms, using constant settling) who are calibrated and show a good agreement with measured data. However, they do not grow below thermocline (~10m), while we see some chla concentration there in the measured data. The limits (incl. light) and growth rate show there must be no problem below 10m, however, I always see zero concentration of the both groups below 10m. I tried to adjust many different parameters in wq_files, including temperature limits, sedimentation speed, light attenuation, light limitation, etc. But the outcome is basically the same.
I would be glad to know your idea about it.
Thanks
Behnam
