performance
- 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.
Sea-Level Rise Topic
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 (regridding/remapping, hybrid vertical coordinates)
- 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 (LV notes: mostly done already, just needs hooks to BGC)
- needed to improve ocean boundary layer representation

Tides
- needed for estuary modeling project
variable time step
- would allow two-way coupling of open to coastal system models
Surface wave model
- needed for inundation modeling
- needed for improved ocean boundary layer modeling
Coastal BGC - Coupled river-estuary-coastal ocean reaction eqs.
- includes inorganic carbon chemistry
- extending BGC into the coastal ocean system
Sediment transport
- needed for the evolution of the coastline and BGC processes

Marine BGC
