And the findings also reveal that the Earth lost 28 trillion tonnes of ice between 1994 and 2017 – equivalent to a sheet of ice 100 metres […]

Climate and carbon cycle trends of the past 50 million years reconciled

Squid-inspired robot swims with nature’s most efficient marine animals

Scientists at the University of Southampton and University of Edinburgh have developed a flexible underwater robot that can propel itself through water in the same style as nature’s most efficient swimmer – the Aurelia aurita jellyfish. The findings, published in Science Robotics, demonstrate that the new underwater robot can swim as quickly and efficiently as […]

Study shows how network of marine protected areas could help safeguard Antarctic penguins

New research led by BirdLife International, the University of East Anglia (UEA) and British Antarctic Survey highlights how a proposed network of marine protected areas could help safeguard some of the most important areas at sea for breeding Antarctic penguins. The findings, published today in the journal Frontiers in Marine Science, show that if all […]

A sea of rubbish: ocean floor landfills

The Messina Strait, a submarine bridge separating the island of Sicily from the Italian Peninsula, is the area with the largest marine litter density worldwide -more than a million objects per square kilometre in some parts-, as reported in a new review paper published in the journal Environmental Research Letters. Also, over the next thirty […]

Scientists offer road map to improve environmental observations in the Indian Ocean

MIAMI–A group of more than 60 scientists have provided recommendations to improve the Indian Ocean Observing System (IndOOS), a basin-wide monitoring […]

Changing resilience of oceans to climate change

Oxygen levels in the ancient oceans were surprisingly resilient to climate change, new research suggests. Scientists used geological samples to estimate ocean oxygen during a period of global warming 56 million years ago – and found “limited expansion” of seafloor anoxia (absence of oxygen). Global warming – both past and present – depletes ocean oxygen, […]

Upper ocean temperatures hit record high in 2020

Scientists discover slimy microbes that may help keep coral reefs healthy

Corals have evolved over millennia to live, and even thrive, in waters with few nutrients. In healthy reefs, the water is often exceptionally clear, mainly because corals have found ways to make optimal use of the few resources around them. Any change to these conditions can throw a coral’s health off balance. Now, researchers […]
