Today, deep waters formed in the northern North Atlantic fill approximately half of the deep ocean globally. In the process, this impacts on the circum-Atlantic climate, regional sea level, and soak up much of the excess atmospheric carbon dioxide from industrialisation — helping to moderate the effects of global warming.
The circulation of water in the Atlantic Ocean reversed its direction less than 20,000 years ago, a study has found.
New NASA measurements show that the Gulf Stream has not slowed down over the past 15 years. In fact, it may even have sped up slightly.
The calving of a massive Antarctic iceberg is expected to affect ocean circulation worldwide, causing colder winters the other side of the world.
