The northeastern Atlantic and the Mediterranean Sea share geological histories and display great faunal aYnities. The majority of the Mediterranean species have Atlantic origins, with a few species with tropical aYnities. These include the parrotWsh Sparisoma cretense and the wrasse Thalassoma pavo that are restricted to the subtropical northeastern Atlantic, the Macaronesian archipelagos (Azor...

1767 NOVEMBER 2007 AMERICAN METEOROLOGICAL SOCIETY | R ecent literature has been refocusing on the association between tropical North Atlantic Ocean sea surface temperature (SST) and Atlantic hurricane activity. Emanuel (2005) demonstrated this relationship using a power dissipation index (PDI), which depends on storm intensity and the lifetime of each storm over each hurricane season. Emanuel’...

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...

Rainfall variability over the Amazon basin has often been linked to variations in Pacific sea surface temperature (SST), and in particular, to the El Niño/Southern Oscillation (ENSO). However, only a fraction of Amazon rainfall variability can be explained by ENSO. Building upon the recent work of Zeng (Environ Res Lett 3:014002, 2008), here we provide further evidence for an influence on Amazo...

AIM The aim of this work was to improve understanding about the mode, geography and tempo of diversification in deep-sea organisms, using a time-calibrated molecular phylogeny of the heterobranch gastropod genus Scaphander. LOCATION Atlantic and Indo-West Pacific (IWP) oceans. METHODS Two mitochondrial gene markers (COI and 16S) and one nuclear ribosomal gene (28S) from six Atlantic species...

Variability of the North Atlantic Oscillation and the Tropical Atlantic dominate the climate of the North Atlantic sector, the underlying ocean and surrounding continents on interannual to decadal time scales. Here we review these phenomena, their climatic impacts and our present state of understanding of their underlying cause. Copyright © 2001 Royal Meteorological Society.

In this study, a mechanism is demonstrated whereby a large reduction in the Atlantic thermohaline circulation (THC) can induce global-scale changes in the Tropics that are consistent with paleoevidence of the global synchronization of millennial-scale abrupt climate change. Using GFDL’s newly developed global coupled ocean–atmosphere model (CM2.0), the global response to a sustained addition of...

The Atlantic Healthcare Collaboration for Innovation and Improvement in Chronic Disease (AHC) Quality Improvement Collaborative (QIC) in Eastern Canada provided an approach to spur system-level reform across multiple health systems for patients and families living with chronic disease. Developed and led by senior executives with a unique governance approach and involving clinical front-line tea...

Deep basins of the North Atlantic were occupied by a cold 13 C-depleted (nutrient-rich) water mass during glaciations, and a warmer 13C-enriched (nutrient-poor) water mass (modern NADW) during interglaciations. This mode of deep-water variability is related directly to migration of the North Atlantic Polar Front. Down-core stable isotope records from the Atlantic and Antarctic suggest that 13C ...
