Secrets of the deep may hold key to life on other planets

Extraordinary creatures who inhabit extreme underwater conditions are being investigated by University scientists in a three-year project. These deep-sea communities could reveal an evolutionary history different to anything else on earth and even give us clues to how life could exist on other planets.

The creatures live around hydrothermal vents – incredibly hot environments in the deep sea – and are unique because they depend on bacteria living inside them for their own survi

Oil companies help marine biologists to explore new frontiers in deep-sea oceanography

An idea from a young marine biologist at the National Oceanography Centre, Southampton is revolutionising oceanography in the deep oceans. Dr Ian Hudson has been getting the oil industry to sign up to a project that has captured the imagination of companies and oceanographers across the world.

Animals in the deep oceans are now being filmed using robotic vehicles and cameras operated by oil companies. As they seek out new oil reserves on the deep-sea floor or carry out mainten

Envisat and ERS-2 reveal hidden side of Hurricane Rita

As Hurricane Rita entered the Gulf of Mexico, ESA’s Envisat satellite’s radar was able to pierce through swirling clouds to directly show how the storm churns the sea surface. This image has then been used to derive Rita’s wind field speeds.

Envisat acquired this Advanced Synthetic Aperture Radar (ASAR) image at 0344 UTC on 22 September (2345 on 21 September in US Eastern Daylight Saving Time), when Hurricane Rita was passing west of Florida and Cuba. The image

Squeezing out dune plants

“Coastal erosion, global sea-level rise, and the loss of sand dune plant habitats”

Researchers from Texas A&M University created a model to better understand the impacts of development and coastal erosion on plant communities, including plants that grow in the ever-shrinking strip of habitat between land and the ocean. Rusty Feagin, Douglas Sherman, and William Grant simulated varying levels of sea-level rise to understand the effects of erosion and development on sand dune p

Marine bacterium suspected to play role in global carbon and nitrogen cycles

Scientists successfully grow ’dwarf belonging to the sea’ in laboratory

Scientists are now revisiting, and perhaps revising, their thinking about how Archaea, an ancient kingdom of single-celled microorganisms, are involved in maintaining the global balance of nitrogen and carbon. Researchers have discovered the first Archaea known to oxidize ammonia for energy and metabolize carbon dioxide by successfully growing the tentatively named, Nitrosopumilus maritimus, in the lab.

Impact of global warming on weather patterns underestimated

The impact of global warming on European weather patterns has been underestimated, according to a new report published in Nature this week.

Dr Gillett, of the University of East Anglia’s Climatic Research Unit, compared Northern Hemisphere air pressure changes at sea level over the past 50 years with predicted changes from nine state-of-the-art climate models.

The Northern Hemisphere Circulation study found that present climate change models – computer representations of
