Phytoplankton bloom off the coast of Japan •

Today’s Image of the Day from NASA Earth Observatory shows a large phytoplankton bloom off the coast of Hokkaido, Japan.

Dominated by the Oyashio current, or the “parent stream,” blooms are very common in this region.

The current carries cool water from the Bering Sea and subArctic North Pacific, which contains iron and other nutrients. As a result of upwelling, additional nutrients are brought to the surface, making the conditions here perfect for phytoplankton growth.

This image was captured in late May by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Aqua satellite.
