Temporal and Spatial Variability of Black Sea Hydrodynamics and Chlorophyll: A Concentration with Connection to Wind Forcing
Spatial and temporal variability of the Black Sea surface circulation with the link to chlorophyll-a concentration and surface winds is investigated using Satellite data from Archiving, Validation, and Interpretation of Satellite Oceanographic data (AVISO), Sea-viewing Wide Field-of-view Sensor (Sea...
