I thank my shipboard colleagues for ongoing discussions, in particular Gianreto Manatschal and Brian Tucholke for insights into the significance of the results from Site 1277. I also thank Othmar Müntener and Brian Tucholke for discussion of results after the cruise. Gianreto Manatschal and Othmar Müntener are also thanked for leading field trips to the Alpine ophiolites, which illustrated similarities with Site 1277. The manuscript benefited considerably from comments by O. Müntener, B. Tucholke, and an anonymous reviewer; discussions with G. Fitton and T. Ustaömer also assisted. G. White assisted with drafting of figures. I also thank Brian Tucholke for his help with editing the paper.
