Dear Jean Pierre and Lennart,
Dear Joan Albert, Thank you for your input. Lennart mentioned that Kimberlee Baldry (kimberlee.baldry@utas.edu.au) will be involved. I hope she follows this thread, if not you can contact her directly. I suggest to make a branch to experiment the revised function. Best, Jean-Pierre
Dear Madams and Sirs, when I calculate the example of SOP3b, I will get a pretty good result (2260.03 umol/kg-?). It is closer to the specified value 2260.06 umol/kg-sol) SOP3b_Example_Calculation_Gran_NLLS_20201027.xlsx , as it is with the NLLS-function (2259 umol/kg-sol) from the scribbs institution. The density calculation of the acid-NaCl can be made external: http://www.aim.env.uea.ac.uk/aim/density/density_electrolyte.php SOP_3b_Seacarb_at-function.txt I am a bit confused about the two different units umol/kg (which is the CRM) and umol/kg-sol, which is sometimes used in the software packages. Are you so polite to explain it to me? Thanx.
Hi, I note that Andrew Dickson replied to your question on the OA Information Exchange. Note that the at function was removed, hopefully temporarily, from seacarb. The reason is that bugs were found. Jean-Pierre
Dear Jean-Pierre,
thank you for your fast response. In deed. Andrew answered. But I have still the problem to understand, why mol/kg-sol is somehow the same as mol/kg. In the Softwarepackage AquaEnf it is not the same. mol/kg-sol = Molinity and mol/kg = Molality. I am able to prepare the NaCl containing acid in mol/kg-sol, without calculation, but not in mol/kg. Therefor I need to use the density of the acid-NaCl-mixture. This algorithm is not implemented into most of the software packages,I am able to use. I am very bad in processing... When I want to refer to the CRM of the Scribbs, than it is in mol/kg - Andrew says mol/kg-sw is equal to mol/kg. Is that true for every Seawater? I am not the only one, who is not able to understand that circumstance clearly. Thank you very much.
best regards Matthias
