+This directory contains scripts written by Jake Gebbie for diagnosing
+subduction rates. All scripts are for offline diagnostics in MATLAB.
 
 
+Eulerian maps of subduction:
+  diag_sann.m: Diagnose the annual subduction rate.
+  diag_induction.m: Diagnose lateral induction across a surface (usually the
+   mixed-layer base)
+  get_mldvel.m: Interpolate the velocity field to a surface (usually the
+    mixed-layer base)
+  
+Water-mass diagnostics:
+  To be included at a future date.
+
+Utilities:
+  mldepth.m: Calculate mixed-layer depth from the density field.
+  cshift.m: A MATLAB replica of the popular Fortran function.
+  integrate_for_w.m: A MATLAB rendition of the MITgcm subroutine 
+    of the same name.
