Hi Chi-tuan,
Thanks for your reply. That's really helpful.
About the suggestions you talked about before, I have talked with other people who agree that the manual is not really clear, especially the density law number 5. Because of this, if I may, I'll suggest rephrasing a little bit the density laws explanation, just to leave no room for doubts:
• 5: the sediment, temperature, and salinity are not considered in the calculations of density. The density is constant, equal to the value given by the AVERAGE WATER DENSITY parameter (default 1025).
Again, many thanks,
Cristian
