Phytoplankton

This is how the bloom collapses: four giant hexagon-shaped viruses that have replicated in a unicellular alga (the rough texture on the right) are on their way out to infect more algae. Three of the viruses are normal and ready for action - and one is white and empty of DNA. Photo: Dr. Daniela Shatz

Bloom the marine wilderness and absorb carbon from the atmosphere

  • One response
The American company Ocean-Based Climate Solutions has developed a pump system that will pump nutrients from a depth of 400 meters to the surface and allow the growth of tiny algae that will perform the photosynthesis process and absorb the carbon

How do sulfur-loving bacteria contribute to the rapid decline of algal blooms in the ocean?

  • One response
Algal particles emitted from samples infected with the virus. Instead of particles up to a micron in size, phytoplankton remains up to four microns in size were discovered

Where does the algae go after they die?
