• performance (Philip Jones)
  
  • Change number of layers to 64 or 128 for vector performance
  • Always loop vertically to nVertLevels, or multiples of 8, with a mask ("Strip-mining")
  • reduce excessive diagnostics computations, other items, see: /wiki/spaces/OCNICE/pages/82673686
• analysis
  
  • Continued work on analysis members and MPAS Analysis
  • smooth automated implementation in ACME, working at high resolution.

• non-Boussinseq / TEOS-10 (Mark Petersen)
  
  • needed for steric SLR
  • expected for next generation ocean models
• wetting-drying / massless layers (Xylar Asay-Davis)
  
  • needed for ocean / land-ice coupling, moving grounding line

  • mitigates errors associated with strongly sloped layer interfaces
• quasi-Lagrangian vertical coordinate (regridding/remapping, hybrid vertical coordinates) (Luke Van Roekel (Unlicensed))
  
  • exploits a capability built into MPAS-Ocean
  • should improve representation / preservation of water masses
• super-cycling of tracer transport
  • needed to make BGC more computationally tractable
• Mesoscale eddy closure
