The isotopic composition of silicic acid and biogenic Si along the WOCE SR3 transect (142-144 ̊E; spring 2001) was analysed by MC-ICP-MS, following Cardinal et al. (2003). We sampled the Subantarctic Zone (SAZ), the Subantarctic Front (SAF), the Polar Front Zone (PFZ), the Interpolar Front Zone (IPF...
