A lump of gas hydrate extracted from the seabed

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.

Researchers will develop a new laboratory instrument capable of simulating the high pressures and…

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.

Geologists will tell you that, in terms of the Earth’s history, this is no new…

Fossil and modern coccolithophore cells of species Toweius pertusus and Coccolithus pelagicus (courtesy of Paul Bown, UCL)

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.

Coccolithophores, a type of plankton, are not only widespread in the modern ocean but…

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.

Projected increases in global mean sea level, caused by melting of land ice and…

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

Blooms, or proliferations, of jellyfish can show a substantial, visible impact on coastal populations – clogged nets for fishermen, stinging waters for tourists, even choked cooling intake pipes for power plants – and recent media reports…

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.

Dr Jörg Wiedenmann, head of the centre’s Coral Reef Laboratory has been selected by the European Research Council to receive funding through…

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.

Shot, edited and broadcast while on board the research drill ship, JOIDES Resolution, the videos featured scientists working to retrieve…

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.

During the last few million years, global ice-volume variability has been one of the main feedback mechanisms in climate change, because of the strong reflective properties of large ice sheets.…

Scientists have developed a new approach for evaluating past climate sensitivity data to help improve comparison with estimates of long-term climate projections developed by the Intergovernmental Panel on Climate Change (IPCC).

The sensitivity of global temperature to changes in the Earth’s radiation balance (climate sensitivity) is a key factor…

Are there more tropical cyclones now than in the past – or are we just hearing more about them through media, and detecting them more successfully with satellites?

That is the question addressed in new research from Denmark’s Niels Bohr Institute, which demonstrates an increasing tendency for cyclones to occur when the climate is warmer, as it has…
