Ocean 'sneezes' spread algae-infecting virus

Microscopic phytoplankton, or microalgae, permeate ocean surfaces, sometimes forming huge blooms visible from space. Nutrient concentrations in seawater are known to regulate such blooms, which play a major role in oceanic food chains and carbon cycling, and occasionally prove harmful to other marine life as well as humans. Less understood are the other factors that influence a bloom’s onset and demise. New research sheds light on one such influence, demonstrating that an algae-infecting virus can become airborne and travel long distances, potentially infecting and eradicating parts of a bloom hundreds of kilometers away.

EARTH only uses professional science journalists and scientists to author our content?  In this era of fake news and click-bait, EARTH offers factual and researched journalism. But EARTH is a non-profit magazine, and at least 10 times more people read EARTH than pay for it. As advertising revenues across the media decline, we need your help to ensure that we can continue bringing you the reliable and well-written coverage of earth science you know and love. Our goal is not only to inform our readers, but to inform decision makers across the economic and political spectrum about the science of our planet. So, we need your help. By becoming a subscriber or making a tax-deductible contribution to support EARTH, you can fund our writers and help make sure the world knows about our planet.
