The reduction of oxygen in the ocean can lead to the disappearance of the main residents of the depth – Lantenfish glowing. This conclusion was given by scientists from Barcelona autonomous university, analyzing sedimentary varieties at the bottom of the Mediterranean. Learn Opublikovano Communication & media environment.
Lantenfish -Small -SEAA lives at a depth of 200-1000 meters. Despite the modest size, biomass, they can be the most vertebrates on the planet – about 600 million tons. They play an important role in climate and food chain regulations, moving daily to the surface to get food and return to depth. Their quantity is an important health indicator of the entire middle region.
Russian scientists have studied the deepest community of marine animals
However, data from sedimentary rocks shows that: In the stages of strong oxygen loss, the Lantenfish population almost disappears, only returns after recovering the normal oxygen level about six thousand years ago. This makes scientists emit alarming sounds: The modern speed of the oxygen dehydration threatens the repetition of this script – but is on a global scale.
As the authors of the study warned, the middle area (the “sunset” of the ocean) is particularly prone to oxygen loss. Its degradation can violate the work of the planetary climate system, worsen the condition of the marine ecosystem and affect the food safety of the world.
Earlier, scientists reported the approach of an environmental disaster in the ocean. It turned out that the ocean world has surpassed the “planetary border” of acidity.
