From Anchovies to Sardines and Back—Multidecadal Change in the Pacific Ocean

TLDR
In the Pacific Ocean, air and ocean temperatures, atmospheric carbon dioxide, landings of anchovies and sardines, and the productivity of coastal and open ocean ecosystems have varied over periods of about 50 years as discussed by the authors.
Abstract
In the Pacific Ocean, air and ocean temperatures, atmospheric carbon dioxide, landings of anchovies and sardines, and the productivity of coastal and open ocean ecosystems have varied over periods of about 50 years. In the mid-1970s, the Pacific changed from a cool “anchovy regime” to a warm “sardine regime.” A shift back to an anchovy regime occurred in the middle to late 1990s. These large-scale, naturally occurring variations must be taken into account when considering human-induced climate change and the management of ocean living resources.

Decadal Sea Level Variability in the South Pacific in a Global Eddy-Resolving Ocean Model Hindcast

TL;DR: In this article, the authors investigated sea level variability and related oceanic changes in the South Pacific from 1970 to 2003 using a hindcast simulation of an eddy-resolving ocean general circulation model (OGCM) for the Earth Simulator (OFES), along with sea level data from tide gauges since 1970 and a satellite altimeter since 1992.

Extratropical control of recent tropical Pacific decadal climate variability

Lixin Wu
TL;DR: In this article, a coupled ocean-atmosphere model, forced by the observed decadal wind in the extratropical North Pacific, explicitly demonstrates that extarropical decadal sea surface temperature (SST) anomalies may propagate to the tropics through a coupled wind-evaporative-SST (WES) feedback.

Strategic Implementation Plan

TL;DR: The NCPN's regional centers of excellence are recognized leaders in the introduction of the highest quality, regionally adapted, true-to-type propagative plant materials that are free of targeted plant pathogens and pests, thus promoting a vigorous commercial environment and the opportunity for international trade while protecting the environment as discussed by the authors.

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.

Climate change impacts on global food security

TL;DR: The evidence supports the need for considerable investment in adaptation and mitigation actions toward a “climate-smart food system” that is more resilient to climate change influences on food security.

Climate-driven trends in contemporary ocean productivity

TL;DR: Global ocean NPP changes detected from space over the past decade are described, dominated by an initial increase in NPP of 1,930 teragrams of carbon a year, followed by a prolonged decrease averaging 190 Tg C yr-1.

Empirical evidence for North Pacific regime shifts in 1977 and 1989

TL;DR: 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.

ENSO as an Integrating Concept in Earth Science

TL;DR: Research to address many intertwined issues regarding ENSO dynamics, impacts, forecasting, and applications remain unresolved will lead to progress across a broad range of scientific disciplines and provide an opportunity to educate the public and policy makers about the importance of climate variability and change in the modern world.
