-This chapter describes the interface between MITgcm and the large 
-scale optimization schemes employed in the ECCO project.
-The interface provides the so-called ``ECCO environment'', which
-is maintained alongside the kernel MITgcm code.
+This chapter describes packages that have been introduced for ocean state estimation purposes and in relation with automatic differentiation (see Chapter~\ref{chap:autodiff})
