Thanks Simon! I can use the functional approach to bridge the gap between this and more traditional forms of data assimilation. At the moment, though, what I am doing is related to your work with soap films, in which your response comes from linearly combine solutions of a PDE evaluated at the po

Eli, I think that this should be possible. If your integration allows you to express the salinity as a weighted sum of evaluated values of the spatial smooth function (where the weights are known), then you could use the summation convention for smooths described in ?linear.functional.terms.
