Silica dissolution rates were measured using the Si-29 isotope dilution techniques of Nelson & Goering 1977. Experiments were performed on 1.5 liter seawater samples collected using either the trace metal clean rosette system or the CTD rosette system.
Data from Survey 2 (KIWI8) lost due to technical difficulties.
