Biological Analysis
The shallower areas of the Black Sea are cooler and less salty. Beneath this top layer, salinity increases, as do concentrations of sulfides. The sea is generally a dark blue when seen from space, but can have swirls of turquoise which would indicate large concentrations of phytoplankton.
Tourist Destination
Cities along the Black Sea are popular locations of holiday resorts. The south-eastern region of Bulgaria alone is home to dozens of sea and resort towns, including Burgas and Sveti Vlas. The Danube River enters the Black Sea through Romania; cruises are popular through this region.
