Comment:

MLD: mixed layer depth related to 0.125 kg/m3 density offset from surface (Miller, 1976).

a: Hydrographic data (S: Salinity, Theta: Pot. temperature, Sigma theta: Pot. Density, O2: Oxygen) measured onboard R/V Sonne cruise SO223T.

b: ?n: Neutral density derived by Ocean Data View (Schlitzer, R., Ocean Data View, http ://odv.awi.de, 2014).

c: Propagated error is calculated from internal and external errors (2?), with external errors deriving from repeated measurements of JNdi-1 standards during each analytical session.

d: QF: Quality Flag Scheme after IODE: 1 = good data, 3 = questionable/suspect data (http://www.iode.org/index.php?option=com_oe&task=viewDocumentRecord&docID=10762).

e: external error is derived from independently processed GEOTRACES seawater standard SAFe 3000 m (n=16), if the internal error of a sample was higher than the external error, the internal error is reported.

f: total procedural replicate for ?Nd and [Nd].

g: Epsilon Nd re-analyzed.

h: re-processed and re-analyzed [Nd].
