ss be 98 Available online 6 April 2008 The many recent publications on regimes and shifts highlight the importance of decadal variability in et al. (2004) go so far as to state that management practices that ignore the impacts of such climate variability on the abundance trends of commercially important species could lead to the col-lapse of major fisheries. There have been over 100 papers pub-lished on regime shifts, with two major recent compilations: an ICES session in 2004 on ‘‘Regime Shifts in the North Atlantic Ocean: Coherent or Chaotic ” and an issue of Progress in Oceanography induce bi-stable modes in marine ecosystems. The purpose of this paper is to review regime shifts as applied to physical and biological timeseries for the North Pacific; it pursues a more conceptual than analytic approach. We highlight some of the differences in emphasis and semantics noted in several recent pub-lications and provide an update on current thinking on the charac-ter of low frequency climate variability in the North Pacific. Marked transitions have occurred in various North Pacific indices as noted in Section 3, although there is still some subjectivity in applying the label of regime shifts.
