Stirring Up A Bloom Off Patagonia

They say art comes from people and animals, but that is not always the case.  Two different ocean currents stirred up a different nutrients and microscopic plants just in time for the summer solstice.  The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Aqua satellite captured the picture when the massive phytoplankton bloom exploded off the Atlantic coast of Patagonia on December 21, 2010.  Using seven different colors of spectral bands, scientists were able to highlight the differences in the plankton communities across the ocean.

Out of the mix of warmer, saltier coastal waters from the suntropics and the colder, fresher waters from the south, explodes this creamy, milky green-blue mixture.  When the currents collide they pull up nutrients from the deep ocean bottom.  Mix in some sun and there is a vast amounts of phytoplankton (food) for everything, from fish to whales.
