Variability of the ocean carbon cycle in response to the North Atlantic Oscillation

Interannual variability in the North Atlantic Ocean carbon sink.

The North Atlantic is believed to represent the largest ocean sink for atmospheric carbon dioxide in the Northern Hemisphere, yet little is known about its temporal variability. We report an 18-year time series of upper-ocean inorganic carbon observations from the northwestern subtropical North Atlantic near Bermuda that indicates substantial variability in this sink. We deduce that the carbon ...

The Role of Atlantic Ocean-Atmosphere Coupling in Affecting North Atlantic Oscillation Variability

We review the role of ocean-atmosphere interactions over the Atlantic sector in North Atlantic Oscillation (NAO) variability. The emphasis is on physical mechanisms, which are illustrated in simple models and analyzed in observations and numerical models. Some directions of research are proposed to better assess the relevance of Atlantic air-sea interactions to observed and simulated NAO variab...

The response of Iberian rivers to the North Atlantic Oscillation

In this study we analyzed the influence of the North Atlantic Oscillation (NAO) on the streamflow in 187 sub-basins of the Iberian Peninsula. Monthly and one-month lagged correlations were conducted to assess the spatiotemporal extent of the NAO influence on Iberian river discharges. Analysis of the persistence of the winter NAO throughout the year was also undertaken, together with analysis of...

The Response of Freshwater Ecosystems to Climate Variability Associated with the North Atlantic Oscillation

Freshwater ecosystems have been repeatedly shown to respond significantly to large-scale climatic fluctuations [e.g., Strub et al., 1985; Firth and Fisher, 1992; George and Taylor, 1995; Anderson et al., 1996; Schindler, 1997]. Because human demand for high-quality fresh water is continually increasing, the practical relevance of such responses for the large-scale management of inland waters is...
