Pioneering study calculates Arctic Ocean nutrient budget

Carving through Arctic ice

The first study of its kind to calculate the amount of nutrients entering and leaving the Arctic Ocean has been carried out by scientists based at the National Oceanography Centre, Southampton.

Global warming will bring more Atlantic hurricane storm surges

Extreme storm events of the magnitude of Hurricane Katrina will occur more frequently because of climate change, according to a new study involving the National Oceanography Centre in Liverpool.

New tool for measuring frozen gas in ocean floor sediments

A new collaboration between the National Oceanography Centre (NOC) and the University of Southampton is seeking to improve geophysical remote sensing of seafloor methane gas and hydrate through innovative laboratory experimental and theoretical studies.

When did modern rates of sea level rise start?

Professor Philip Woodworth of the National Oceanography Centre (NOC) in Liverpool and Professor Roland Gehrels of Plymouth University asked when sea level rise started to accelerate – and narrowed it down to a point in the early 1900s.

Global sea levels are rising.

Climate change clues from tiny marine algae – ancient and modern

Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago. The study found that their response to environmental change varies between species, in terms of how quickly they grow.

European flood risk research recognised by Lloyd’s of London

High tide in South Devon

To understand the risk of coastal flooding, you need to understand the tides. This was a key message of a study by researchers based at the National Oceanography Centre in Liverpool and Southampton, which was short-listed for the recent Lloyd’s Science of Risk Prize.

Jellyfish experts show increased blooms are a consequence of periodic global fluctuations

Scientists have cast doubt on the widely held perception that there has been a global increase in jellyfish.

Coral researcher recognised with prestigious award

Research into a process that is threatening to wipe out coral reefs, by a scientist at the National Oceanography Centre, Southampton, has been recognised with a prestigious award worth 1.29 million euros.

Video diaries go back millions of years

JOIDES Resolution

Video of deep-ocean drilling research will be featured at this year’s 2012 AGU meeting in California, including the debut of a new 20-minute documentary of the expedition in the Atlantic this summer.

New dating of sea-level records reveals rapid response between ice volume and polar temperature

Iceberg

A new study has revealed a rapid response between global temperature and ice volume/sea-level, which could lead to sea-levels rising by over one metre.
