Ocean depth of half surface SST

Hi,

I have several ocean variables on 4-d (t, lev, lat, lon). I want to:

1. Determine the depth at which the temperature (t, lev, lat, lon) equals half the value of SST (t, lat, lon). So the new variable have dimension (t, lat, lon) containing various depths from the grids.

2. Using the new variable from (1), I'd like to extract other variables corresponding to the depths and other dimensions in (1).

From the examples, I know that linear interpolation is get the depth of a particular value (http://www.ncl.ucar.edu/Applications/iso.shtml). My problem is that the value I'm interested in (1/2 SST) will change from grid point to grid point.

Thanks in advance for any suggestions.

Hyacinth
