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:

Impacts of natural and anthropogenic climate variations on North Pacific plankton in an Earth System Model
TL;DR: In this paper, the impacts of natural atmospheric variability and anthropogenic climate change on the spatial distribution, seasonality, structure, and productivity of North Pacific plankton groups are investigated by means of an Earth System Model (ESM) that contains a plankton model with variable stoichiometry.
The salmon malbec project: a north pacific-scale study to support salmon conservation planning
Nathan J. Mantua,Nathan G. Taylor,G.T. Ruggerone,K.W. Kyers,David Preikshot,X. Augerot,N.D. Davis,B. Dorner,R. Hilborn,R.M. Peterman,P. Rand,Daniel E. Schindler,Jack A. Stanford,R.V. Walker,Carl J. Walters +14 more
TL;DR: The Model for Assessing Links Between Ecosystems (MALBEC) as discussed by the authors is a policy gaming tool with potential to explore the impacts of climate change, harvest policies, hatchery policies, and freshwater habitat capacity changes on salmon at the North Pacific scale.

On Drawing Conclusions Nine Years After the Exxon Valdez Oil Spill
TL;DR: In this article, the authors discuss concerns about the effects on the study design of inherent differences between the oiled and unoiled areas, about interpretations of results that use inconsistent criteria to define the spatial scales of analysis, and about explanations of underlying causes that are not empirically founded.

Reduction of nutrient emission from Polish territory into the Baltic Sea (1988–2014) confronted with real environmental needs and international requirements
Marianna Pastuszak,Andreas C. Bryhn,Lars Håkanson,Per Stålnacke,Mariusz Zalewski,Tycjan Wodzinowski +5 more
TL;DR: In this paper, the authors present and discuss Polish riverine flow normalized loads of total nitrogen (TN) and total phosphorus (TP) in the Baltic Sea and discuss the major threats to its ecological status.

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.

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.
