TLDR
In this paper, the authors used 100 environmental time series, 31 climatic and 69 biological, to determine if there is evidence for common regime signals in the 1965-1997 period of record.About:

Assessing the ecological importance of climate regime shifts: An approach from the North Pacific Ocean
TL;DR: In this article, the authors used an indicator approach to address the ecological importance of low-frequency climate variability in the northeast Pacific Ocean using a set of 33 climate and 64 biology time series, updated by them for the years 1965-2011 (for climate data) and 1965-2008 (for biology data).

Catastrophic dynamics limit Atlantic cod recovery.
Camilla Sguotti,Saskia A. Otto,Romain Frelat,Tom J. Langbehn,Marie Plambech Ryberg,Martin Lindegren,Joël M. Durant,Nils Chr. Stenseth,Christian Möllmann +8 more
TL;DR: It is suggested that a continuing increase in ocean temperatures will probably limit productivity and hence future fishing opportunities for most cod stocks of the Atlantic Ocean and the importance of considering discontinuous dynamics in holistic ecosystem-based management approaches, particularly under climate change is highlighted.

Detecting the impact of oceano‐climatic changes on marine ecosystems using a multivariate index: The case of the Bay of Biscay (North Atlantic‐European Ocean)
Georges Hemery,Frank D'Amico,Iker Castège,Bernard Dupont,Jean D'elbee,Yann Lalanne,Claude Mouchès +6 more
TL;DR: In this paper, a multivariate Oceanic and Climatic index (MOCI) was proposed to describe regional scale patterns of marine animal populations. But it is not suitable to describe local weather variables in the explanation of trends in animal numbers.

Reconstructing historical marine ecosystems using food web models: Northern British Columbia from Pre-European contact to present
TL;DR: In this article, a mass-balance trophic model was developed for the marine ecosystem of northern British Columbia (BC) for the historical periods 1750, 1900, 1950 and 2000 AD.

Interannual variability in chlorophyll concentrations in the Humboldt and California Current Systems
TL;DR: In this article, the first systematic comparison of 10 years (1997-2007) of chlorophyll interannual variability over the California (CCS) and Humboldt (HCS) current systems is presented.

A Pacific interdecadal climate oscillation with impacts on salmon production
TL;DR: In this article, the authors identify a robust, recurring pattern of ocean-atmosphere climate variability centered over the midlatitude North Pacific basin over the past century, the amplitude of this climate pattern has varied irregularly at interannual-to-interdecadal timescales.
Journal ArticleDOI
The Arctic oscillation signature in the wintertime geopotential height and temperature fields
TL;DR: The Arctic Oscillation (AO) as mentioned in this paper is the signature of modulations in the strength of the polar vortex aloft, and it resembles the NAO in many respects; but its primary center of action covers more of the Arctic, giving it a more zonally symmetric appearance.

Teleconnections in the Geopotential Height Field during the Northern Hemisphere Winter
John M. Wallace,David S. Gutzler +1 more
TL;DR: In this paper, a review of existing literature on the subject reveals the existence of at least four such patterns: the North Atlantic and North Pacific Oscillations identified by Walker and Bliss (1932), a zonally symmetric seesaw between sea level pressures in polar and temperature latitudes, first noted by Lorenz (1951), and what we will refer to as the Pacific/North American pattern, which has been known to operational long-range forecasters in this country since the 1950's.

Classification, seasonality and persistence of low-frequency atmospheric circulation patterns
TL;DR: In this article, Orthogonally rotated principle component analysis (RPCA) was used to identify and describe the seasonality and persistence of the major modes of interannual variability.
