Res. Lett., 39, L03704, doi:10.1029/2011GL050722. Introduction This auxiliary material contains a text file consisting of four tables and five figures with their captions. There are also five sections of text with their references that clarify, expand, and supplement the information provided in the main text. In addition to this, there is a spreadsheet with all the stable isotope measurements. 1. 2011gl050722-txts01.pdf Text S1. Text 1.
