Study provides insight into how some species thrive in dark, oxygen-free environments
- A study revealed that metallic rocks on the Pacific Ocean's seabed can produce oxygen in dark, oxygen-free environments, challenging previous scientific beliefs about oxygen production.
- Andrew Sweetman from the Scottish Association for Marine Science is leading a three-year project to investigate dark oxygen production further, funded by the Nippon Foundation.
- Research on foraminifera by the Woods Hole Oceanographic Institution showed that these organisms survive in dark, oxygen-free environments by using chemoautotrophy to obtain energy.
- NASA is interested in the findings related to dark oxygen as it may provide insights into how life could exist on other planets without sunlight.

New study provides insight into how some species thrive in dark, oxygen-free environments
A new study sheds light on how a species of foraminifera, single-celled organisms found in almost all marine habitats, thrives in a dark, oxygen-free environment.
Study provides insight into how some species thrive in dark, oxygen-free environments
Most life on Earth relies on the sun's energy for survival, but what about organisms in the deep sea that live beyond the reach of its rays? A new study led by Woods Hole Oceanographic Institution (WHOI), published in The ISME Journal, sheds light on how a species of foraminifera, single-celled organisms found in almost all marine habitats, thrives in a dark, oxygen-free environment.
