aThe weighted average was calculated as the integral divided by the depth at which it was calculated.
bD_Pycnocline is the maximum depth influenced by the pycnocline, and it was calculated as the depth at which the second derivative of the function of density with depth oscillates in the range of +/-0.005 kg/m.
cEx-DOC indicate the excess of DOC with respect to 48 muM.
dTurnover time for excess DOC (TTex-DOC = exDOC/BCD).
