Based on the research just posted above Planetary and terrestrial science letters, An analysis of the gas hydrate deposits here is that methane is trapped in water molecules, hidden in an ice-like solid, in the “Danube fan” region, the area of fan-shaped sediments in the northwest. of the Black Sea. Weakness accumulates in the Danube River, which revealed that the ice age in this place never really ended.

The group of authors led by Dr. Michael Riedel of the GEOMAR Helmholtz Center for Ocean Research (Germany) sought the basis of the “gas hydrate stable zone” (GHSZ), which meets temperature, pressure and various other conditions. that allow gas hydrates to form naturally. . Above and below this “stable zone”, the methane will be in a free state, not trapped in the hydrate.
The GHSZ region is not limited to fixed numbers, but will vary with planetary changes. By drilling into the sea floor and measuring the temperature, the researchers conclude that the GHSZ region in most of the Earth has adapted to warmer conditions over the past millennia and has changed dramatically.
But in the mysterious Black Sea, the adaptive response has been delayed. The GHSZ here is similar to the GHSZ on the surface at the time of the last ice age that is not over yet. This deep system seems only to perceive the end of the era of reconciliation and struggle.
According to the Scientific alert, This finding will help in future climate modeling. Science has shown that there are huge volumes of gas hydrate fields beneath the Arctic and how they respond to rising global temperatures in the coming years will have a significant effect on the climate.
