slow salinity instability at base of steep bathymetry
Hi, I'm finding that the salinity is slowly increasing above that of any of my end members. I'm using the MPDATA advection scheme which I am thrilled solved my problem of salinity at the river input blowing up. Instead, I am seeing a slow upward creep of salinity, with the highest salinities along the edges of steep bathymetry (which is pretty smooth). Has anyone found such a gradual (i.e. 0.2 PSU over 20 days) instability associated with bathymetry? I'd appreciate any suggestions on how to solve it (other than further smoothing which I'm trying). thanks, Amanda

Hi Amanda
I had somthing similar where things built up beyond any value that was set at the boundary. I don't remember what it was, but I think I found it by looking at the detailed diagnostic output for tracers and seeing what the source was.
