Study first to experimentally explore the joint impact of fishing and ocean warming on fish populations, finding that the viability of wild populations and global fish stock are at risk
Researchers using a new method involving the mineral barite have dated the first emergence of continental crust to 500 million years earlier than previously thought. The results will be presented at the European Geosciences Union (EGU) General Assembly 2021, which is taking place from 19-30 April 2021.
Corals and sponges are important foundations in ocean ecosystems providing structure and habitats that shelter a high number of species like fish, crabs and other creatures, particularly in the seamounts and canyons of the deep sea. Researchers at the University of New Hampshire have discovered that when it comes to climate change not all deep-sea corals and sponges are affected the same and some could be threatened if average ocean temperatures continue to increase in the deep sea of the Northwest Atlantic.
Scientists have identified a new phylum of microbes found around the world that appear to be playing an important (and surprising) role in the global carbon cycle by helping break down decaying plants without producing the greenhouse gas methane. The phylum is named Brockarchaeota after Thomas Brock, a pioneer in the study of microbes that live in extreme environments who died on April 4.
A new study suggests the white shark population for the eastern north Pacific, especially those listed in the Gulf of California, might be underestimated. Researchers found that the mortality rates for these white sharks might be underestimated as well, as an illicit fishery for the species was uncovered in the Gulf of California, suggesting that fishers were killing many more white sharks than has been previously understood.
A new study has demonstrated how video games can be used as a citizen science approach to train artificial intelligence tools, with data contributing towards coral reef conservation efforts. The NeMO-Net video game, designed by researchers at NASA's Ames Research Center in California's Silicon Valley and led by principal investigator Dr Ved Chirayath, provides an educational and intuitive tool for players to learn about and explore coral reef ecosystems, whilst also bringing marine conservation research to wider audiences.
Scientists have provided the first evidence to show that eradicating rats from tropical islands effects not just the biodiversity on the islands, but also the fragile coral seas that surround them.
Volcanic eruptions deep in our oceans are capable of extremely powerful releases of energy, at a rate high enough to power the whole of the United States, according to research published today.
The Northwest Atlantic Shelf is one of the fastest-changing regions in the global ocean, and is currently experiencing marine heat waves, altered fisheries and a surge in sea level rise along the North American east coast. A new paper authored by experts at the University of Rhode Island and published in Communications Earth & Environment reveals the causes, potential predictability and historical context for these types of rapid changes.
A German-French study led by the GEOMAR Helmholtz Centre for Ocean Research Kiel has used long-term observations to investigate the complex interplay between fluctuations in the equatorial current system and variations in oxygen content. During the last 15 years the intensification of upper-ocean currents resulted in an increasing oxygen content in the equatorial region.
