Synchronous ecological regime shifts in the central Baltic and the North Sea in the late 1980s
The index of the North Atlantic Oscillation, the dominant mode of climatic variability in the North Atlantic region, changed in the late 1980s (1987e1989) from a negative to a positive phase. ThisExpand

Climate Variability, Fish, and Fisheries
Abstract Fish population variability and fisheries activities are closely linked to weather and climate dynamics. While weather at sea directly affects fishing, environmental variability determinesExpand

Regime shifts in the Humboldt Current ecosystem
Abstract Of the four major eastern boundary currents, the Humboldt Current (HC) stands out because it is extremely productive, dominated by anchovy dynamics and subject to frequent directExpand

Worldwide large-scale fluctuations of sardine and anchovy populations
Decade-scale regimes of sardine Sardinops sagax and anchovy Engraulis spp. have been observed in the productive coastal waters of the North-Western, North-Eastern and South-Eastern Pacific and theExpand

Long‐term climate forcing of European herring and sardine populations
Records of the herring, Clupea harengus, fishery off the Swedish coast of Bohuslan, in the Skagerrak, date back to the 10th century. Nine periods, each lasting several decades, are known during whichExpand

Detecting regime shifts in the ocean: Data considerations
We review observational data sets that have been used to detect regime shifts in the ocean. Through exploration of data time series we develop a definition of a regime shift from a pragmaticExpand

Marine Ecosystem Response to the Atlantic Multidecadal Oscillation
Against the backdrop of warming of the Northern Hemisphere it has recently been acknowledged that North Atlantic temperature changes undergo considerable variability over multidecadal periods. TheExpand

Climate controls on marine ecosystems and fish populations
Abstract This paper discusses large-scale climate variability for several marine ecosystems and suggests types of ecosystem responses to climate change. Our analysis of observations and model resultsExpand

Population synchronies within and between ocean basins: Apparent teleconnections and implications as to physical-biological linkage mechanisms
Abstract Major fish populations in large marine ecosystems separated by thousands of kilometres often seem to fluctuate in decadal-scale synchrony indicating strong forcing of ecosystem processes andExpand
