Reply to Helle et al.

We are grateful for the opportunity to respond to Helle, Lumma and Jokela's (henceforth HLJ; [Helle et al. 2010][1]) comment on our work. HLJ attribute to us the conclusion that the results in [Helle et al. (2002)][2] were ‘probably false positive owing to smaller sample size’. This is puzzling
