Abstract:
In general, the Black Sea basin has no vertical circulation off - shore, due to the great density stratification, which prevents the profound convection processes. The Black Sea streams are strictly horizontally therefore is missing the permanent upwelling and downwelling phenomenon like in other areas of the Planetary Ocean. In the last years, it has been felt the upwelling phenomenon at the shore, manifested by a severe cooling of the surface waters. There are two main ways to identify areas of upwelling. One method is to look at Sea Surface Temperature (SST). Another way to identify areas of upwelling is by using maps of chlorophyll on the surface of the sea. Chlorophyll is a telling signal of upwelling due to the fact that upwelled water brings with it nutrients and dissolved gases that are important for plant growth. The list includes nitrogen, phosphorous, silica and carbon dioxide. With these being brought to the surface, where sunlight is also available, marine plants including microscopic phytoplankton (algae) grow very well.
