Around this time of year, the Black Sea blooms with a massive growth of phytoplankton. This particular species of phytoplankton known as coccolithophores, are plated with white calcium carbonate, making the bloom very easy to see from space. NASA's Aqua satellite gathered these data.

Two NASA Satellites were used to create this image of the straight of Gibraltar: Suomi NPP, and Aqua. The images were processed and combined to highlight the blooms of phytoplankton in the area, which has been caught up in the turbulent ocean currents moving through the strait.
