Here, we calculate absolute Archaean barometric pressure using the size distribution of gas bubbles in basaltic lava flows that solidified at sea level ~2.7 Gyr in the Pilbara Craton, Australia. Our data indicate a surprisingly low surface atmospheric pressure of P= 0.23 +/- 0.23 (2蟽) bar,...

On the surface the product of 70 Ukrainian NGOs, this was, in reality, a massive affront to democracy and the rule of law: Its sole purpose was to unconstitutionally constrain the newly elected president with so-called “red lines” and, in particular, nullify what so many of his voters ...
A sustainable separation concept for large-scale recycling of NdFeB magnets under atmospheric pressure was developed by utilizing a combination of two separation concepts known from the literature: (I) selective pre-separation by in situ chlorination and evaporation of ground oxidized NdFeB material and...
Earth has a strong magnetic field, similar to a magnet bar, due to the molten iron and nickel in its core, or that's what geophysicists are pretty certain is the cause. This flow of liquid creates electric currents, which, in turn, generate the magnetic field. Since the early 19th centu...
Atmospheric rivers play an integral role in the global water cycle, but predicting their future changes remains uncertain due to inter-model and inter-detection-method differences. Using ultra-high-resolution Community Earth System Model simulations and a novel detection algorithm based on geometric shap...
e Flexpart footprints in 2D projections (stereographic). Colors (from black to white, see left color bar) on each grid point represent the number of particles over the 10-days back trajectory. This number is normalized by the total number of particles (on the 10-day period) and then ...
Right now on the surface of the planet; it looks like it’s just a bar magnet. Our compasses are just pointing to one pole at a time because there’s mainly a two-pole system. But sometimes, the earth doesn’t just have a single magnetic North and South Pole. Evidence suggests that...
We also review the current plans for missions in Earth orbit that will help better quantify the atmospheric losses processes and also their effects on the Earth’s upper atmosphere and magnetosphere. In Sect. 3 we review past studies and current plans to use noble gases in the atmospheres of ...
