Severity of these effects depends on disturbance size, proximity to the auroral zone, and the conductivity structure of the Earth. Also significant are system parameters such as the use of higher resistance coatings on pipelines and the ... DH Boteler,RJ Pirjola,H Nevanlinna - 《Advances in Sp...

400 km (238,900 miles). TheMoonis one of the bigger natural satellites in the solar system; only the giant planets have moons comparable or larger in size. Some planetary astronomers consider the Earth-Moon system a double planet, with some similarity in that regard to thedwarf planetPluto...

Full size image Our assessment builds upon and advances beyond previous research and science-based political consensus, such as the Planetary Boundaries (PBs) framework27, doughnut economics28and the Sustainable Development Goals29in the following ways. (1) We define just ESBs for avoiding significant...
Fluid/peridotite interaction leads to dissolution/precipitation processes, grain size reduction, and peridotite weakening at short time scales Such peridotite weakening explains intense strain localization within the ductile mantle wedge and the observed switch in the subduction interface regime Abstract Full ...

Full size image Modern OIBs, which are thought to sample a deeper mantle reservoir than MORBs46, provide an opportunity to explore the possible survival of a primordial material in the lower mantle. Although the sources of modern OIBs and enriched-MORBs (E-MORBs) record large δ49Ti variabi...
We developed a comprehensive, gridded Global Soil Dataset for use in Earth System Models(GSDE) and other applications. The GSDE provides soil information, such as soil particle--size distribution,organic carbon, and nutrients, and quality control information in terms of confidence level at 30" ...
