Fresh water from melting glaciers Mixes with Ocean
These two bodies of water were merging in the middle of The Gulf of Alaska and there was a foam developing only at their junction. It is a result of the melting glaciers being composed of fresh water and the ocean has a higher percentage of salt causing the two ocean bodies of water to have different densities and therefore makes it more difficult to mix.
This happens when glaciers of fresh water start melting and flow to join the ocean water which is more salty. Because of the difference in the salinity and densities of these two meeting ocean water bodies, a surface tension is developed between them that acts like a thin wall and does not allow them to mix. But given enough time, they will eventually mix together.
