London: Scientists have found that a gas released from the oceans on Earth may play a significant role in the destruction of ozone layer.

Researchers at the Universities of York and Leeds found that the principal source of iodine oxide can be explained by emissions of hypoiodous acid (HOI) — a gas not yet considered as being released from the ocean — along with a contribution from molecular iodine (I2). Since the 1970s when methyl iodide (CH3I) was discovered as ubiquitous in the ocean, the presence of iodine in the atmosphere has been understood to arise mainly from emissions of organic compounds from phytoplankton — microscopic marine plants.

South of Africa, the Agulhas ocean current system transports warm, salty water from the Indian Ocean to the Atlantic Ocean. This study shows that the mesoscale variability of the Agulhas system has intensified over recent decades, apparently owing to enhanced trade winds over the tropical Indian Ocean.

A massive iceberg — twice the size of Manhattan — has broken off of a glacier in Greenland, according to NASA satellite imagery, in what could be the latest indication of global warming.

The images released on Wednesday show the massive chunk of ice breaking off of the Petermann Glacier on the north-western coast of Greenland. The glacier produced a similar ice island twice as large in 2010.

South of Africa, the Agulhas Current retroflects and a portion of its waters flows into the South Atlantic Ocean, typically in the form of Agulhas rings. This flux of warm and salty water from the Indian to the Atlantic Ocean (the Agulhas leakage) is now recognized as a key element in global climate. An Agulhas leakage shutdown has been associated with extreme glacial periods, whereas a vigorous increase has preceded shifts towards interglacials.

In January of this year, a comprehensive study of animals in the Southern Ocean was completed, showing that the region is under threat from climate change.

The National Oceanic and Atmospheric Association today designated the Atlantic sturgeon an endangered species, providing it greater legal protections, following a petition the Natural Resources Def

More than twenty years ago, a biological regulation of climate was proposed whereby emissions of dimethyl sulphide
from oceanic phytoplankton resulted in the formation of aerosol particles that acted as cloud condensation nuclei in the
marine boundary layer. In this hypothesis—referred to as CLAW—the increase in cloud condensation nuclei led to an
increase in cloud albedo with the resulting changes in temperature and radiation initiating a climate feedback altering

New research from the University of Missouri indicates that Atlantic Ocean temperatures during the greenhouse climate of the Late Cretaceous Epoch were influenced by circulation in the deep ocean.

For the first time, scientists have discovered mysterious deep seat jets of water which cause anomalies in wind, rainfall and sea temperature across the tropical Atlantic.

Past research has shown that the oceans impact climate in a multitude of ways, most notably with the ocean-atmosphere phenomena known as El Nino and La Nina, where patterns of warmth and cold in the Pacific wreak havoc world

The rising temperature of the world's oceans has become a major threat to coral reefs globally as the severity and frequency of mass coral bleaching and mortality events increase. In 2005, high ocean temperatures in the tropical Atlantic and Caribbean resulted in the most severe bleaching event ever recorded in the basin.
