v14 v15 62 62 See attachment for plots of surface Fe anomalies (relative to CTL) for parameterized ice shelf cavities (Fig. 1) and resolved ice shelf cavities (Fig. 2) when activating Fe input from the Antarctic ice sheet (nn_ais_tr = 1, prescribed tracer concentration in iceberg and ice shelf). \\ 63 63 - The results for the parameterized ice shelf cavities are as expected with a net positive effect on surface Fe concentrations.\\ 64 - For the resolved ice shelf cavities, the results are more surprising as there are areas with a positive effect on surface iron concentrations and areas with a negative effect potentially induced by seawater circulation in cavities. This point deserves further investigation, in particular regarding the initial conditions in the cavities for T, S, and nutrients.64 - For the resolved ice shelf cavities, the results are inconsistent - there are areas with a positive effect on surface iron concentrations and areas with a negative effect potentially induced by seawater circulation in the cavities (Fig. 2). This inconsistency is probably related to the lack of initial conditions for T, S and nutrients. A run will be made once the initial condition files in the cavities are constructed (cf work by K. Hutchinson). 65 65 66 66 The model outputs are available on jeanzay (idris)
