Scientists from Stockholm University and the Swedish Museum of Natural history, in collaboration with partners in Greenland and Canada, have identified a previously undocumented class of PFAS* in the blubber of killer whales.
The new study, published in Environmental Science and Technology Letters, reveals the presence of five fluorotelomer sulfones—highly fluorinated, lipophilic (fat-loving) chemicals never before reported in wildlife. Unlike well studied PFAS, which typically accumulate in protein-rich tissues such as liver and blood, these new substances accumulate in fat-rich blubber.
Rising sea levels could cause seasonal waves to reach Ahu Tongariki, the iconic ceremonial platform that is part of the Rapa Nui National Park, a UNESCO world heritage site by 2080, according to a study published recently by a team of researchers from the University of Hawai‘i at Mānoa. This coastal flooding also threatens to impact up to 51 cultural assets in the area, including Rapa Nui’s world renowned moai statues.
A research team from the Institut de Ciències del Mar (ICM-CSIC) has published a study in Communications Biology showing how ocean acidification and warming — two of the main consequences of global climate change — can simultaneously affect the structure, mineral composition, and microbiome of bryozoans, colonial invertebrates crucial for forming marine habitats. The findings point to potentially serious ecological consequences under a scenario of accelerated climate change.
A groundbreaking study by marine scientists has revealed that sea-level rise in the Indian Ocean began accelerating far earlier than previously thought, with corals providing an unbroken natural record of ocean change stretching back to the early 20th century. Published in Nature Communications, the study was led by Professor Paul Kench from the National University of Singapore. By analysing coral samples from the Maldives in the central Indian Ocean, the scientists reconstructed a century-long chronology of sea-level changes and climate shifts with remarkable precision. They were able to extend the sea-level record for the Indian Ocean back a further 60 years, all the way to the early 1900s, offering a much longer and clearer historical context for interpreting modern sea-level changes.
