This happened
because fresh
water glaciers
melted and
flowed to join the
ocean water. Because of the
difference in the
salinity and
densities of these two water bodies, a surface
tension developed between them that acts like
a thin wall which prevents them from mixing. The boundary between the two is outlined by a
thin layer of foam. It’s kind of poetic isn’t it? Two powerful bodies
of water, relentlessly standing together, but
unable to become one. They’re like the Romeo
and Juliet of aquatic bodies. But fear not,
hopelessly romantic weirdos, according to
scientists this story will get its happy ending; given enough time, the differences between
these two bodies will disappear and they will
merge together.
