'''1) ocean physics & diagnostics''' :  incorporating or developing  improved ocean physics, diagnostics and numerics coming either from the NEMO community or from the NEMO team[[BR]]


   LOCEAN 12 - output of 3D trend for tracers, momentum, Kinetic Energy and Potential Energy  (see #927 and  [https://forge.ipsl.jussieu.fr/nemo/browser/branches/2012/dev_r3309_LOCEAN12_Ediag      2012/dev_r3309_LOCEAN12_Ediag ] ) [[BR]] 
   NOCS 11- enhanced Fox-Kemper parametrisation[[BR]]  

'''2) Surface forcing''' : upgrading the surface forcing (new  bulk formulea, better SSS restoring through the spectral nudging,  simple light penetration, and a full reformulation of the surface  fluxes) [[BR]]



'''3) Sea-ice development''' : upgrading the sea-ice by embedding sea-ice inside the ocean, improving EVP rheology for both LIM2 and 3,  and improving LIM3

  NOCS 5 -  Embedding LIM (end) and CICE inside the ocean  [[BR]]   
  LOCEAN - revised coding of EVP rheology[[BR]]  
  UCL - Newly formed ice representation[[BR]]  
  UCL - Long term developments of LIM3 (snow model, ice rheology, bio-ice component) (ongoing)
