ocean (Mark Petersen)

non-Boussinseq / TEOS-10
- needed for steric SLR
- expected for next generation ocean models
wetting-drying / massless layers
- needed for ocean / land-ice coupling, moving grounding line
- needed for coastal inundation
high-order pressure gradient
- mitigates errors associated with strongly sloped layer interfaces
quasi-Lagrangian vertical coordinate
- 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
- funded by SciDAC3, in code base, needed to be validated in global configurations
thin-wall approach for bottom bathymetry
- a great idea that we never have time to implement
improved vertical turbulence scheme
- needed to get beyond KPP
prognostic SW penetration model
- needed to improve ocean boundary layer representation
