It's in the natural cycle of the North Atlantic Ocean to turn green every summer, when plankton blooms and becomes noticeable even from satellite. Made up of hundred of billions of small microorganisms and tiny crustaceans, it represents the basis of the marine ecosystem, and is indispensable to life in the oceans. For more than 50 years, scientists thought they had an explanation as to why this cycle occurred and what caused it. Now, a decade's worth of satellite investigations proved the theory bogus. Until now, marine biologists thought that the plankton was generated when summer heat radiated into the ocean. The temperature rose constantly, and then, once a certain threshold was reached, life began to appear. This is the common-sense theory, and its deductibility was one of the main reasons why it was seldom questioned. Now, experts prove with the help of ten years' worth of satellite readings that this is not what happens in reality, and that the plankton begins to bl!
oom at the end of the winter season. “We found that the north Atlantic bloom was starting much earlier than we thought and it didn’t coincide with an improvement in the growth conditions from the phytoplankton. It started in January,†Oregon State University phytoplankton ecologist Michael Behrenfeld explains, quoted b...
