Layout of the in situ ice-growth experiments.
Layout of the set-up for Exp 1 and 2 (aerial view). Cores were separated by 0.1 m. For each time step, one row (cores A–E for Exp 1 and A–F for Exp 2) was sampled for a suite of parameters. T1 sampling was at 6 hours, T2 at 12 hours, T3 at 24 hours and T4 at 48 hours. Core allocation was as follows for Exp 1: core A, temperature and ice texture; core B, salinity and bacterial counts; core C, POC/PON, DOC, macro-nutrients and Chl a; core D, EPS; and core E, PFe and DFe. Core allocation during Exp 2 was: core A, temperature and ice texture; core B, salinity and bacterial count; core C, POC/PON, DOC, macro-nutrients; core D, Chl a; core E, EPS; and core F, PFe and DFe.
