Antarctic ice sheets capable of retreating up to 50 meters per day
The ice shelves surrounding the Antarctic coastline retreated at speeds of up to 50 metres per day at the end of the last Ice Age, far more rapid than the satellite-derived retreat rates observed today, new research has found. The…

Study shows erosion of ozone layer responsible for mass extinction event
Researchers at the University of Southampton have shown that an extinction event 360 million years ago, that killed much of the Earth’s plant and freshwater aquatic life, was caused by a brief breakdown of the ozone layer that shields the…

There is no escaping from climate change, even in the deep sea
Even though the deeper layers of the ocean are warming at a slower pace than the surface, animals living in the deep ocean are more exposed to climate warming and will face increasing challenges to maintain their preferred thermal habitats…
The deep ocean is warming slowly — but dramatic changes are ahead
The world’s deep oceans are warming at a slower rate than the surface, but it’s still not good news for deep-sea creatures according to an international study. The research, led by University of Queensland PhD student Isaac Brito-Morales, looked at…
Coastal engineers: ‘Thinkers’ facing rising seas
The latest theories and applied examples stemming from the authors’ 48 years of experience in teaching, research and practice as a professional engineer are presented in his new book.
Ocean waves play a critical role in shaping our economy, weather and climate
Turns out, it’s all in the water
Towable sensor free-falls to measure vertical slices of ocean conditions
Instrument may help scientists assess the ocean’s response to climate change
Mysterious glowing coral reefs are fighting to recover
A new study by the University of Southampton has revealed why some corals exhibit a dazzling colourful display, instead of turning white, when they suffer ‘coral bleaching’ – a condition which can devastate reefs and is caused by ocean warming.…

How climate killed corals
Multiple factors joined forces to devastate the Great Barrier Reef in 2016
Even biodiverse coral reefs still vulnerable to climate change and invasive species
A new study reveals clear evidence highlighting the importance of fish biodiversity to the health of spectacular tropical coral reef ecosystems. This is the case for reefs that are pristine and also those that have been affected by stresses, such…

Ocean ‘breathability’ key to past, future habitat of West Coast marine species
Marine life off the West Coast, from Mexico up through Canada, inhabit the California Current. The cool, nutrient-rich water supports life from invisible phytoplankton to the economically important salmon, rockfish and Dungeness crab to the majestic orcas. A new study…
