Sulfur enhances carbon storage in the Black Sea: Study finds new explanation for the accumulation of organic compounds in oxygen-depleted marine areas
The Black Sea is an unusual body of water: below a depth of 150 metres the dissolved oxygen concentration sinks to around zero, meaning that higher life forms such as plants and animals cannot exist in these areas. At the same time, this semi-enclosed sea stores comparatively large amounts of organic carbon. A team of […]
Researchers recreate deep-Earth conditions to see how iron copes with extreme stress: New observations of the atomic structure of iron reveal it undergoes
Far below you lies a sphere of solid iron and nickel about as wide as the broadest part of Texas: the Earth’s inner core. The metal at the inner core is under pressure about 360 million times higher than we experience in our everyday lives and temperatures approximately as hot as the Sun’s surface. Earth’s […]
The environment for permafrost in Daisetsu Mountains in Japan is projected to decrease significantly
Areas with ground temperatures that remain below 0°C for more than two years are referred to as permafrost, and approximately one quarter of the Northern Hemisphere and 17% of the Earth’s exposed land surface is permafrost. Permafrost is found in mountainous areas as well as in high-latitude tundra and taiga regions. Recent observations have shown […]
