Melting Arctic sea ice could affect global ocean circulation, research warns
Melting sea ice can cause temperatures to drop. Credit: Karine Nigar Aarskog / UiT Norwegian Arctic University A warming climate in the polar regions could significantly disrupt ocean circulation patterns, a new study shows. Scientists have discovered that in the distant past, melting Arctic sea ice may have increased the flow of freshwater into the Nordic Seas, significantly impacting ocean…

North Sea oil pollution is ‘significantly underestimated’, new report suggests
Credit: Unsplash/CC0 Public Domain Growing up in Aberdeen, Scotland, the shadow of the Piper Alpha disaster loomed large over our community. A tragic explosion on an oil drilling platform in 1988 claimed the lives of 167 people. At that time, I was fortunate not to know about the impact that disaster would have on the ecosystem. However, the 670 tonne…

Researchers from the University of Adelaide have developed a new theoretical model that predicts the distances ocean waves will travel to break up sea ice. Monitoring ocean wave propagation is important for…

Understanding Antarctica’s impact on sea level rise
Antarctic bedrock landforms and drainage basins and their estimated potential for global mean sea level rise (in metres). Areas considered particularly vulnerable are highlighted in blue. Source: Australian Antarctic Data Centre, 2024. DOI: 10.26179/q3fx-8p19 Will melting of the Antarctic Ice Sheet (AIS), Earth’s largest ice mass, cause global sea levels to rise by 5 metres, 2 metres or even less…

Sea turtles make a comeback on beaches at two British military bases in Cyprus
Credit: Pixabay/CC0 Public Domain Protected green and loggerhead sea turtles are enjoying a major comeback on the beaches of two British military bases on the island of Cyprus, with nest numbers exceeding last year’s record by nearly 25 percent, conservationists said on Tuesday. A total of 382 sea turtle nests have been recorded across all beaches on base this year,…
