    2222=== Description 
    2323 
     24Improve OSMOSIS ocean boundary layer (OBL)  model in 3 areas: 
    2425 
     261. Ensure consistent behaviour of OSMOSIS-OBL under ice. Revert to classic shear turbulence based on ice-ocean turbulent friction velocity where ice areal coverage is high; scale with ice fraction between shear turbulence and Langmuir turbulence model. Where Stokes drift unavailable, move to parametrised form. 
     27 
     282. Improve representation of OSMOSIS-OBL mixing in equatorial regions. Include mixing associated with shear of mean flow as in equatorial undercurrent. 
     29 
     303. Mixing in shelf seas. The OSMOSIS-OBL is primarily a surface boundary layer model and so is not set up for bottom-driven tidal mixing. We intend to transition to GLS in shelf seas.
