It looks menacing, but it's so good that fish everywhere are clapping and cheering. For once, here you have a flood invading the oceans that isn't evil, like the one caused by BP. This is the annual phytoplankton bloom.
Every year, a massive phytoplankton bloom spreads across the North Atlantic, moving from south to north and peaking in the late spring. This image shows a manifestation of the North Atlantic bloom west of Iceland.
The green and blue flood of life is made of phytoplankton, gazillions of microscopic organisms that process light and nutrients, creating oxygen. It was photographed by NASA's Aqua satellite using its Moderate Resolution Imaging Spectroradiometer.
Meanwhile, the situation in the Gulf of Mexico keeps being a total disaster. [NASA]
