Diamonds and water in the deep Earth: a new scenario
Earth is a water planet, but how much water exists on and in the Earth? Is the water limited to the Earth’s surface and limited depths of our planet (molecular water of the hydrosphere), or do deep reservoirs of hydrogen and oxygen really exist as proposed in recent works but not yet proven? Due to the importance of H2O for life and geological processes on the Earth, these questions are among t...
متن کاملWarm water occupancy by North Sea cod.
The North Sea has warmed in recent years and there is an ongoing debate into how this is affecting the distribution of fishes and other marine organisms. Of particular interest is the commercially important Atlantic cod (Gadus morhua L.), which has declined sharply in abundance in the North Sea over the past 20 years. Observations of the temperature experienced by 129 individual cod throughout ...
متن کاملIncreasing Diamonds
A class of diamond-shaped combinatorial structures is studied whose enumerating generating functions satisfy differential equations of the form f2 “ Gpfq, for some function G. In addition to their own interests and being natural extensions of increasing trees, the study of such DAG-structures was motivated by modelling executions of seriesparallel concurrent processes; they may also be used in ...
متن کاملWarm Water Vapor around Sagittarius B2
In the region of Sgr B2 there are several condensations heated externally by nearby hot stars. Therefore H2O far–IR lines are expected to probe only an external low–density and high temperature section of these condensations, whereas millimeter-wave lines can penetrate deeper into them where the density is higher and Tk lower. We have conducted a study combining H2O lines in both spectral regio...
