Scientists have revealed the secret of mysterious spots off the coast of the Baltic Sea

As a result of long studies conducted by scientists from different countries, it was possible to find out the origin of mysterious spots on the Baltic Sea, which have been observed for decades. Such spots on satellite images look like swirling patterns and appear due to wind currents and waves. However, until now it was unknown what exactly forms such spots.

As reported in the journal Remote Sensing of Environment, after extensive research, scientists have concluded that the reason for the formation of these spots is a high concentration of pine pollen (Pinus sylvestris), which is carried away by the wind from Poland to the Baltic Sea. This version was proposed earlier, but now it has been confirmed by scientific data.

Interestingly, the volume of pollen concentration in these spots has increased from year to year, and on satellite images for the period from 2000 to 2021, such spots have already been recorded 14 times. Scientists attribute this to climate change on the planet and note that pines in Poland are a widespread tree species and cover a third of its territory.

Previously, scientists did not assume that pine pollen could reach so far from the coast, but new scientific data allow us to conclude that climate change affects not only the trees themselves, but also the environment.

These discoveries of scientists allow a deeper understanding of the nature and impact of human activity on the environment. We hope that such research will continue and help preserve the balance in nature for future generations.
