Fig. 2: Influences on DMg/Ca, DLi/Ca and DLi/Mg.
Relationships between DMg/Ca, DLi/Ca and DLi/Mg and aragonite precipitation rate (R) or ΩAr as a function of a–c pH at 25 °C, d–f variable temperature and g–i in the presence of amino acids at 25 °C. j–l Relationships between ΩAr and DMg/Ca, DLi/Ca, and DLi/Mg in the presence of amino acids. Best fit linear relationships are fitted to data at 10, 20, and 30 °C in d–f. No AA = no amino acid, Asp = aspartic acid, Glu = glutamic acid, Gly = glycine in g–l. Errors in DMg/Ca, DLi/Ca and DLi/Mg (1.4%, 2.6% and 3.1%, respectively), precipitation rate and ΩAr are smaller than the symbols used (see methods).
