   Sea ice salinity is very low ($\sim4-6 \, psu$) compared to those of the ocean ($\sim34 \, psu$).
   The cycle of freezing/melting is associated with fresh water and salt fluxes that
   cannot be neglected.
+  \item [Land ice - ocean] The ocean and Land ice (ice shelves and drifting icebergs) exchange heat and fresh water. 
+  These interactions represent a significant source of fresh water for the polar ocean regions. 
+  Ice shelves melt in the 200m to 1500m depth range and the buoyant plume generated by the melt triggers specific oceanic circulation and water masses alterations on the Antarctic continental shelf or within Greenlandic Fjords. 
+  Icebergs, on the other hand, are created by the breaking of an ice shelf at the calving front. 
+  Their drift is subsequently driven by winds and ocean currents, redistributing the ice calved from the ice shelf or glacier termini along the Antarctic or Greenland coastline, and toward lower latitudes. 
+  Explicit representation and parametrisation of ice shelves and icebergs is described in \autoref{sec:ISF} and \autoref{sec:ICB} repectively.
