Introduction:

Auxiliary material consists of a table of oxygen isotope data collected by laser fluorination for MORB, compiled from this study and from the literature. 

1. 2009gc002728-ts01.txt
Table S1. Data in this table are those used to construct Figures 2 and 4; note that data shown in Figs. 2 and 4 include AAD data (Table 1) as well as data in this table. Data sources for oxygen-isotope data, as well as radiogenic-isotope, trace-element, and major-element data for the same samples, are as follows: 1 - this study; 2 - Eiler et al. [2000]; 3 - Sims et al [2002]; 4 - Sims et al [2003]; 5 - Cooper et al. [2004]; 6 - Schiano et al. [1997] and references therein.
