Scientists found a terrifying human footprint at the bottom of the Mariana Trench

Scientists made a shocking discovery at the bottom of the Mariana Trench, finding high concentrations of methylated mercury, reports EurekAlert.

According to the scientific platform, researchers definitively link this pollution to human activity, particularly industrial processes that impact even the most inaccessible corners of our planet.

"Most of the mercury enters the ocean precisely due to industrial processes," the material emphasizes.

During the study, soil samples were collected using the modern Deep Sea Warrior submersible at a colossal depth of up to nine kilometers. Scientists hypothesize that the toxic traces could have appeared at such depths as a result of coal or fuel burning. Experts express serious concern that the continuing pollution of the World Ocean could lead to catastrophic deterioration of the marine ecosystem.

Earlier, scientists discovered a sunken mountain with three volcanoes off the coast of the Canary Island of Lanzarote. As noted, the place resembles the mythical Atlantis. The mountain was found during a study of the seabed off the eastern coast of Lanzarote using a remotely operated vehicle.

Before that, it became known that the 20-meter unidentified object discovered in 2011 in a canyon of an underwater mountain in the Gulf of Bothnia in the Baltic Sea has a natural origin. This conclusion was reached by geologists from Stockholm University who studied rocks taken from the structure. In their opinion, the object could have formed during the ice age 140 thousand years ago.
