o New package: pkg/seaice
  Sea ice model by D. Menemenlis (JPL) and Jinlun Zhang (Seattle).
  The sea-ice code is based on Hibler (1979-1980).
  Two sea-ice dynamic solvers, ADI and LSR, are included.
  In addition to computing prognostic sea-ice variables and diagnosing
  the forcing/external data fields that drive the ocean model,
  SEAICE_MODEL also sets theta to the freezing point under sea-ice.
  The implied surface heat flux is then stored in variable
  surfaceTendencyTice, which is needed by KPP package (kpp_calc.F and
  kpp_transport_t.F) to diagnose surface buoyancy fluxes and for the
  non-local transport term.  Because this call precedes model
  thermodynamics, temperature under sea-ice may not be "exactly" at
  the freezing point by the time theta is dumped or time-averaged.
