Philippine Grid: 2 km grid spacing,
(480x350x42 points) refined bathymetry
Regional Grid: 5 km grid spacing (200x250x42 points)
Contour levels (m): -100 -150 -250 -500 -1000 -2000 -4000 -5000
Red line ship track
Motivation: identify observational strategy
Cost function: transport through a cross section over the whole water column averaged over 5 day period.
The plot shows adjoint bathymetry scaled by the difference between real and model bathymetry.
Shows spacial distribution of the variation in the transport through four major straights due to bathymetry.
Singular vectors of salinity at 5m depth, computed over 5 day period on the regional grid.
