Photo from space: NASA showed how the Baltic blossoms

NASA published a picture of a part of the Baltic Sea in July.  At this time, the phytoplankton spreads over the sea and forms a spiral pattern on the surface.

The photo was taken with the help of the Operational Land Imager (OLI) from the satellite Landsat 8.

These green plants on the surface are in fact more often cyanobacteria (blue-green algae) that capture and conserve energy through photosynthesis. Sometimes there can be found diatoms.

The researchers reported that this month the level of oxygen in the sea is at the lowest possible level due to the abundant flowering of phytoplankton. Because of this in the basin appear “dead” zones without fish and other marine life, in these areas all nutrients are eaten by small organisms.

Thanks to the satellites and photographs of the astronauts, we can see our planet from an unusual perspective, including the most incredible of its places:
