Bad Omens Emerge Near Indonesia, More Abundant than a Century Ago

A deposit of silver has been discovered in the northern waters of the Indonesian region, specifically on the floor of the South China Sea. Its concentration has continued to increase more than a century ago.

The findings come from research conducted by Hefei University of Technology and Guangdong Ocean University of China. Research teams collected samples from a depth of 1,878 metres from the seafloor off the coast of Vietnam to study 3,200 years of sediment cores.

The discovery also points to the impact of global warming from human activities. The sampling location is an area continuously exposed to wind, resulting in its replacement with cold, nutrient-rich seawater, making it sensitive to environmental changes.

Records show that silver content on the seafloor has increased since the 1850s. This period marked the beginning of the Industrial Revolution and a surge in atmospheric CO2 levels.

The silver discovered was reported to originate from manufacturing activities, specifically residue from the production of photographic equipment.

Researchers also identified a factor in the increase of summer temperatures in East Asia due to global warming. This causes heavy rainfall and strong winds to bring nutrients to the ocean surface, making marine microorganisms more productive in photosynthesis.

These microorganisms absorb silver material and metal content in seawater. Subsequently, the remains of dead microorganisms carry silver to the seafloor.

This condition could potentially occur along coasts worldwide, not just in the South China Sea.

It turns out the implications of these findings extend beyond silver and mineral deposits. Both could encourage deep-sea mining activities for silver, copper, lead, and gold.

These materials are needed to manufacture batteries, such as nickel, manganese, and cobalt.

If mining activities increase, it will impact the environment, including potentially disrupting marine balance.
