Global warming will leave different fingerprints on global subtropical anticyclones
To assess the possible responses of the subtropical anticyclones to greenhouse gases (GHG) forcing, scientists adopted multiple metrics and obtained robust results. Coupled models under GHG forcing show that the subtropical anticyclones over North Pacific, South Atlantic and South Indian Ocean will become weaker in future under RCP8.5 scenario, whereas the subtropical anticyclones over North Atlantic and South Pacific will become stronger. (2017-08-11)

Switching on the Atlantic heat pump
34 million years ago the warm 'greenhouse climate' of the dinosaur age ended and the colder 'icehouse climate' of today commenced. Antarctica glaciated first and geological data imply that the Atlantic meridional overturning circulation, the global ocean conveyor belt of heat and nutrients that today helps keep Europe warm, also started at this time. Why exactly, has remained a mystery. (2019-08-22)

Amazonian rainfall increases in wet season
Amazonian precipitation in wet season is foun to have largely increased during the past three decades (1979-2015). The results based on model simulation suggest that the tropical sea surface temperature variability may control this process, particularly in Atlantic and Pacific. (2018-08-28)

Ocean invaders in deep time
Much has been made of the economic impacts of recent biological invasions, but what are the implications of invasions in deep time?

(2005-10-13)

Stronger Atlantic currents drive temperate species to migrate towards the Arctic Ocean
The Arctic Ocean increasingly resembles the Atlantic, not only regarding its temperature but also the species that live there. However, scientists from the CNRS and Université Laval, Quebec showed that an unprecedented strengthening of Atlantic currents is playing a major role in this phenomenon called 'Atlantification.' The research team studied Emiliania huxleyi, a marine microalgae that typically lives in temperate waters at lower latitudes. (2020-04-06)

First 'OSNAP' results alter understanding of Atlantic overturning circulation variability
Contradicting the prevailing view on what causes major changes to a climate-regulating ocean circulation pattern in the northern hemisphere, the first results from the 'OSNAP' project, an internationally collaborative effort designed to monitor large-scale ocean dynamics, report that deep water formation in the Labrador Sea does not drive Atlantic Meridional Overturning Circulation (AMOC) variability. (2019-01-31)

Currents could disrupt ocean food chain
If increased precipitation and sea surface heating from global warming disrupts the Atlantic Conveyer current - as some scientists predict - the effect on the ocean food chain in the Atlantic and other oceans could be severe, according to a new study just published in Nature. In a worst case scenario, global productivity of phytoplankton could decrease by as much as 20 percent and in some areas, such as the North Atlantic, the loss could hit 50 percent. (2005-04-12)

NASA catches birth of Tropical Storm Chris by the tail
Several hundred miles from Newfoundland, the third tropical storm of the Atlantic Hurricane Season was born on June 19, and NASA's Aqua satellite captured an image just before it reached tropical storm strength, and he appears to have a (2012-06-20)

Discovering lost salmon at sea
Where Atlantic salmon feed in the ocean has been a long-standing mystery, but new research led by the University of Southampton shows that marine location can be recovered from the chemistry of fish scales. Surprisingly, salmon from different British rivers migrate to feed in separate places, and may respond differently to environmental change. (2011-06-23)

Lee reborn as a tiny zombie hurricane in central Atlantic
