The biological pump (or ocean carbon biological pump or marine biological carbon pump) is the ocean's biologically driven sequestration of carbon from the atmosphere and land runoff to the ocean interior and seafloor sediments. [ 1] In other words, it is a biologically mediated process which results in the sequestering of carbon in the deep ...
The current global average concentration of carbon dioxide (CO 2) in the atmosphere is 421 ppm (0.04%) as of May 2022. [ 1] This is an increase of 50% since the start of the Industrial Revolution, up from 280 ppm during the 10,000 years prior to the mid-18th century. [ 2][ 1][ 3] The increase is due to human activity.
A submersible pump (or electric submersible pump ( ESP) is a device which has a hermetically sealed motor close-coupled to the pump body. The whole assembly is submerged in the fluid to be pumped. The main advantage of this type of pump is that it prevents pump cavitation, a problem associated with a high elevation difference between the pump ...
Measurements of plant carbon allocation to mycorrhizal fungi have been estimated to be 5 to 20% of total plant carbon uptake, [3] [4] and in some ecosystems the biomass of mycorrhizal fungi can be comparable to the biomass of fine roots. [5] Recent research has shown that mycorrhizal fungi hold 50 to 70 percent of the total carbon stored in ...
The US, China and Russia have cumulatively contributed the greatest amounts of CO 2 since 1850. [ 3 ] This is a list of sovereign states and territories by carbon dioxide emissions[ n 1 ] due to certain forms of human activity, based on the EDGAR database created by European Commission and Netherlands Environmental Assessment Agency. The ...

Riccardo Barbieri (born 1944) is an Italian theoretical physicist and a professor at the Scuola Normale Superiore di Pisa. He has written more than two hundred research papers in the field of theoretical elementary particle physics, [1] and has been particularly influential in physics beyond the Standard Model .
