•Horizontal
 Advection
 –Two of the
 thermodynamical variables T, S, and density are advected (user selectable), with the third calculated from the
 equation of state.
 –If HYCOM is run in MICOM mode, advection is performed as in MICOM 2.8, with T and S advected in layer 1 (the mixed
 layer) and S only advected in the
 isopycnic layers.
