TL;DR: It is concluded that the ability to adapt to, or manage, regime shifts depends upon their uniqueness, the understanding of their causes and linkages among ecosystem components and the authors' observational capabilities.

TL;DR: It is suggested that the conversion of warm, salty, shallow Atlantic waters into colder, fresher, deep waters that move southward in the Irminger and Iceland basins is largely responsible for overturning and its variability in the subpolar basin.

TL;DR: In this paper, a pragmatic definition of a regime shift from a pragmatic perspective is presented, in which a shift is considered as an abrupt change from a quantifiable ecosystem state. And the abruptness of the shift is relative to the life-scale or the reproductive time-scale of the higher predators that are influenced by the shift.

TL;DR: A strategy is discussed that builds on recent advances in modeling and observations and a way forward is suggested that includes approaches to coupling across trophic levels and the inclusion of uncertainty.

TL;DR: The Atlantic cod (Gadus morhua) populations located off Labrador and Northeastern Newfoundland (NAFO areas 2G-3L) have recently declined to the lowest levels of abundance on record.
