Baltic and North Sea s
It’s not two oceans meeting, its glacial melt water meeting the off shore waters of Gulf of Alaska. … The reason for this strange phenomenon is due to the difference of water density, temperature and salinity of the glacial melt water and off shore waters of Gulf of Alaska, making it difficult to mix.
The Baltic proper, or Central Baltic Sea, does not normally freeze at all with the exception of sheltered bays and shallow lagoons (such as the Courland Lagoon). The ice reaches a maximum extent in February or March.
Ocean Color. This MODIS image of blue water in the Caribbean Sea looks blue because the sunlight is scattered by the water molecules. Near the Bahama Islands, the lighter aqua colors are shallow water where the sunlight is reflecting off of the sand and reefs near the surface.
Unique feature of the Baltic Sea is its brackish water – a mixture of fresh water and saline seawater. Heavier saline water forms the deeper water layer in the Baltic Sea, whereas the surface water layer is diluted by rain and numerous rivers flowing into the sea. … The food chains in the Baltic Sea are simple.
the main reason is due to the difference between salinity (The concentration of dissolved salts in the water),densities in the two seas.North sea’s salinity is ~35%, an average for ocean’s water where the Baltic sea’s salinity is ~12% in comparison and this difference makes them not merging each other and the color can describe easily.Salt water takes longer time to mix because of its special chemical properties and the ionic charges keeps sodium and chloride separating from the fresh water.Some says that its not mixing of two oceans but glacial melting water meeting offshore waters of Gulf of Alaska
