Emissions from coal-fired power plants in China are fertilizing the North Pacific Ocean with a metal nutrient important for marine life, according to new findings from a USC-led research team. The researchers believe these metals could change the ocean ecosystem, though it's unclear whether it would be for better or worse.
Research led by Micaela Pedrazas, who earned her masters at The University of Texas at Austin Jackson School of Geosciences working with Professor Bayani Cardenas, has found permafrost to be mostly absent throughout the shallow seafloor along a coastal field site in northeastern Alaska. That means carbon can be released from coastline sources much more easily than previously thought.
Marine fish species are migratory in nature and not respectful of human-made territorial boundaries, which represents a challenge for fisheries management as policies tend to focus at the national level. With an average catch of 48 million tonnes per year, and USD $77 billion in annual fishing revenue, these species support critical fisheries, and require international cooperation to manage.
A team of geologists at the University of Houston College of Natural Sciences and Mathematics believes they have found the lost plate known as Resurrection in northern Canada by using existing mantle tomography images.
For the first time, researchers have mapped the biological diversity of marine sediment, one of Earth's largest global biomes. The research team discovered that microbial diversity in the dark, energy-limited world beneath the seafloor is as diverse as in Earth's surface biomes.
Over the past three decades, the depths of the Antarctic Weddell Sea have warmed five times faster than the rest of the ocean at depths exceeding 2,000 metres. This was the main finding of an article just published by oceanographers from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI).
Tropical cyclones, regionally known as hurricanes or typhoons, have been moving across ocean basins faster since 1982, according to a new study by researchers at the University of Hawaii at Manoa.
The latest report from the Living Oceans Foundation finds Palau's reefs had the highest coral cover observed on the Global Reef Expedition--the largest coral reef survey and mapping expedition in history. Published today, the Global Reef Expedition: The Republic of Palau Final Report summarizes the Foundation's research on the status of coral reefs and reef fish in Palau and provides conservation recommendations that can help preserve these outstanding coral reefs for generations to come.
252 million years ago at the boundary between the Permian and Triassic epochs, Earth witnessed a mass extinction event that extinguished about three-quarters of all species on land and some 95 percent of all species in the ocean. Volcanic activity in today's Siberia has long been debated as a likely trigger of this event. Now, an international team of researchers provides for the first time a conclusive reconstruction of the key events that led to the mega-catastrophe.
MIPT researchers Leopold Lobkovsky and Raissa Mazova, and their young colleagues from Nizhny Novgorod State Technical University have created a model of landslide-induced tsunamis that accounts for the initial location of the landslide body. Reported in Landslides, the model reveals that tsunami height is affected by the coastal slope and the position of the land mass before slipping. The highest and most devastating waves result from onshore landslide masses.
