The abundant biological and mineral diversity of the Rio Grande Rise, a seamount in the depths of the Atlantic Ocean about 1,500 km from the coast of Brazil, is probably due to a great extent to little-known microscopic creatures.
Researchers affiliated with the University of São Paulo s Oceanographic Institute (IO-USP), collaborating with colleagues at the UK s National Oceanography Center, investigated the microorganisms inhabiting the seamount s ferromanganese crusts and concluded that bacteria and archaea are probably responsible for maintaining the abundant local life, besides being involved in the process of biomineralization that forms the metals present in the crusts.

New research could help scientists better estimate Earth s carbon budget ANI | Updated: Apr 13, 2021 23:16 IST
Washington [US], April 13 (ANI): A team led by University of Minnesota researchers have discovered that deep-sea bacteria dissolve carbon-containing rocks, releasing excess carbon into the ocean and atmosphere. The findings will allow scientists to better estimate the amount of carbon dioxide in Earth s atmosphere, the main driver of global warming.
The study is published in The ISME Journal: Multidisciplinary Journal of Microbial Ecology, a peer-reviewed scientific journal that is part of the Nature family of publications and the official journal of the International Society for Microbial Ecology (ISME).

A team of researchers from the University of Minnesota has found that deep-sea bacteria dissolve carbon-containing rocks and discharge surplus carbon into the air and ocean.
CSE researchers collected samples of carbonate rocks from the Del Mar East methane seep using a submersible watercraft. They discovered that deep-sea bacteria are dissolving these rocks, releasing excess carbon into the ocean and atmosphere.

The study results will enable researchers to better evaluate the amount of carbon dioxide in Earth’s atmosphere, which is a principal driver of global warming.
