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… Expand
Climate, Anchovy, and Sardine.
It is hypothesized that anchovy and sardine populations are limited in size by the supply of nitrogen from outside their habitats originating from upwelling, mixing, and rivers, and that they may be affected by ocean warming, acidification, deoxygenation, and altered hydrology. Expand
Microbial biogeochemistry of coastal upwelling regimes in a changing ocean
The coastal upwelling regimes located along the eastern boundaries of the Pacific and Atlantic Ocean basins are small in size, but make a disproportionate contribution to the productivity andExpand
Multifarious anchovy and sardine regimes in the Humboldt Current System during the last 150 years
It is shown that a long-term increase in coastal upwelling translates via a bottom-up mechanism to top predators suggesting that the warming climate, at least up to the start of the 21st century, was favorable for fishery productivity in the HCS. Expand
Environmental drivers of the anchovy/sardine complex in the Eastern Mediterranean
The anchovy/sardine complex is an important fishery resource in some of the largest upwelling systems in the world. Synchronous, but out of phase, fluctuations of the two species in distant parts ofExpand
Anchovy population and ocean-climatic fluctuations in the Humboldt Current System during the last 700 years and their implications
A marine sedimentary record collected from 87 m water depth in a coastal environment of the Humboldt Current System (Mejillones Bay, 23° S, northern Chile) was used to reconstruct the past 700 yearsExpand
Hydrographic conditions driving sardine and anchovy populations in a land-locked sea
The aim of this paper is to establish a relationship between long-term variability in sardine and anchovy populations in the Adriatic Sea and ocean dynamics and processes that occur over interannualExpand
Subseasonal organization of ocean chlorophyll: Prospects for prediction based on the Madden-Julian Oscillation
[1] Analysis of satellite ocean color and rainfall data shows that the Madden-Julian Oscillation (MJO) produces systematic and significant variations in ocean surface Chlorophyll (Chl) in a number ofExpand
Influence of Oceanographic Variability on the Planktonic Prey and Growth of Sardine and Anchovy in the California Current Ecosystem
Populations of Pacific sardine (Sardinops sagax) and northern anchovy (Engraulis mordax) have responded differently to oceanographic changes in the California Current Ecosystem (CCE) over the pastExpand
A stochastic model for the Iberoatlantic sardine fishery. Global warming and economic effects
Abstract The literature of natural resources has made wide use of deterministic dynamic models to optimally manage marine fishery resources. However, the ever-changing weather condition and, mostExpand
Contrasting responses in larval and juvenile growth to a climate–ocean regime shift between anchovy and sardine
Anchovy and sardine populations have fluctuated alternately with decadal changes in climatic and oceanic states, although the mechanisms remain unclear. In the western North Pacific, anchovy andExpand


Climate-Ocean Variability and Ecosystem Response in the Northeast Pacific
It is shown that there have been large interannual and interdecadal sea-surface temperature changes off the West Coast of North America during the past 80 years. Expand
A Pacific Interdecadal Climate Oscillation with Impacts on Salmon Production
Evidence gleaned from the instrumental record of climate data identifies a robust, recurring pattern of ocean–atmosphere climate variability centered over the midlatitude North Pacific basin. OverExpand
Sardine and anchovy regime fluctuations of abundance in four regions of the world oceans: a workshop report
Regimes of high abundance of sardine (Sardinops sagax and sardina pikhardw) have alternated with regimes of high abundance of anchovy (Engradis spp.) in each of the five regions of the world whereExpand
World-wide fluctuations of sardine and anchovy stocks: the regime problem
Summed differences between the highest and lowest catches of two clupeoid taxa, sardines Sardinops spp. and Sardina pilchardus and anchovies Engraulis spp., in five regions where they co-occur are inExpand
Coastal Cool-Down
At last month9s Ocean Sciences Meeting in Honolulu, physical and biological oceanographers gathered to discuss the 1999 flip in sea surface temperatures, which chilled waters along the edge of theExpand
Marine nekton off Oregon and the 1997–98 El Nino
Abstract Several species of migratory, warm-water, oceanic fishes invaded Oregon waters during the summer of 1997. Also, the jumbo squid (Dosidicus gigas), common in the eastern tropical Pacific, wasExpand
Biological and chemical response of the equatorial pacific ocean to the 1997-98 El Nino
During the 1997-98 El Nino, the equatorial Pacific Ocean retained 0. 7 x 10(15) grams of carbon that normally would have been lost to the atmosphere as carbon dioxide. The surface ocean becameExpand
Climatic Warming and the Decline of Zooplankton in the California Current
Since 1951, the biomass of macrozooplankton in waters off southern California has decreased by 80 percent and the surface layer warmed and the temperature difference across the thermocline increased, which led to further decline of zooplankton. Expand
Worldwide large-scale fluctuations of sardine and anchovy populations
At high population levels, quality of sardine and their eggs decreased in Japan, leading to decreased production and survival of eggs, poor year-classes and stock collapse. Expand
Slowdown of the meridional overturning circulation in the upper Pacific Ocean
It is shown that the wind-driven meridional overturning circulation between the tropical and subtropical oceans has been slowing down since the 1970s, causing a decrease in upwelling in an equatorial strip between 9° N and 9°S, which is associated with a rise in equatorial sea surface temperatures.
