摘要

Multidecadal variability in the Atlantic Ocean and its importance to the Earth's climate systemhas been the subject of study in the physical oceanography field for decades. Only recently, however, has the importance of this variability, termed the Atlantic Multidecadal Oscillation or AMO, been recognized by ecologists as an important factor influencing ecosystem state. A growing body of literature suggests that AMO-related fluctuations are associated with shifts in ecological boundaries, primary productivity, and a number of ecologically and economically important coastal and marine populations across the Atlantic basin. Although the AMO is a basin-wide index of SST, the drivers of ecosystem change encompass more than temperature anomalies and the mode of action differs within each ecosystem. A common theme in assessing ecosystemchange indicates that fluctuations in water masses and circulation patterns drive shifts in ecosystem states, but the magnitude and rate of change is dependent on the physical characteristics of the region. Because of thewide ranging geographic effects of theAMO, and considering its multidecadal nature, a more complete understanding of its causes and effects would allow scientists and managers to more effectively inform ecosystem-based management across the Atlantic Basin.
