*Subject*: Small error in TA_ITER_1*From*: cvoelker@ifm.uni-kiel.de (christoph voelker)*Date*: Tue, 10 Aug 1999 16:12:52 +0200 (MET DST)

There seems to be a small sign error in the calculation of the derivative of alkalinity with respect to H+ in TA_ITER_1; the term that comes from the alkalinity of the H+-ion has the wrong sign: In fn everything is o.k.: fn = k1*x*dic/b + [snip] & sit/(1.0 + x/ksi) - <------ & x/c - [snip] but in df = dfn/dx the term is wrong: df = ((k1*dic*b) - k1*x*dic*db)/b2 - [snip] & sit/ksi/(1.0+x/ksi)**2. + <------ & 1.0/c + [snip] But since [h+] is of the order of 10^-5 mol/m^3, this probably makes no big difference.
