We thank Chris Clark and an anonymous reviewer for useful constructive criticism that improved the clarity of the paper. Swedish Research Council Grants G-AA/GU 12034-300 and G-AA/GU 12034-301 to Stroeven and National Science Foundation Grants OPP-9818162 and OPP-0138486 to Harbor provided partial support for this work. The Swedish Research Council (2007-15) and Granholmsstiftelse at Stockholm University generously supported Stroeven to host the first of a couple of deglaciation workshops at the Tarfala Research Station in late March–April 2007. Jansen was supported by a UK NERC fellowship (NE/EO14143/1). We thank Helena Alexanderson, John Clague, Timothy Johnsen, Yingkui Li, and Kurt Lambeck for their contribution to the 2007 workshop. The field data has been collected with the help of Ingmar Borgström (2000), Magnus Johansson (2001), Torbjörn Dahlgren (2002), Karin Ebert (2002), Angelica Feurdean (2002), Barbara Wohlfarth (2002), Svante Björck (2003), Eva Sahlin (2003), Vasily Kolka (2004), and Alexandru T. Codilean (2009). We received considerable support at three accelerator facilities (PrimeLab, ANSTO, and SUERC), and we are most grateful to staff at these facilities.
