To understand the role of the ocean in global environmental change and to progress oceanography in developing countries the National Oceanography Centre (NOC) will be leading a working group aiming to build the world’s largest database on carbon flux measurements from optical sensors.

Scientists based at the National Oceanography Centre, Southampton have discovered a previously unrecognised volcanic process, similar to one that is used in chocolate manufacturing, which gives important new insights into the dynamics of volcanic eruptions.

Imaging the molten rock beneath an active volcano

Island of Montserrat

University of Southampton researchers based the National Oceanography Centre, Southampton, with colleagues from Bristol and Penn State Universities, have produced the first image of the magma chamber (body of molten rock) beneath the active Soufrière Hills Volcano on the island of Montserrat in the Caribbean.

Carbon release and global warming now and in the ancient past

Core shed in Spitsbergen

The present rate of greenhouse carbon dioxide emissions through fossil fuel burning is higher than that associated with an ancient episode of severe global warming, according to new research. The findings are published online this week by the journal Nature Geoscience.

Ancient global warmings explained

Episodes of global warming occurred several times during the Palaeocene and Eocene epochs (65–34 million years ago)

A research team including scientists from the University of Southampton’s School of Ocean and Earth Science (SOES) based at the National Oceanography Centre, Southampton, has uncovered the likely cause of repeated episodes of natural global warming during the ancient past.
