The Gulf of Alaska and the Pacific showcase a stunning display of freshwater interacting with the salty Pacific water.

The mesmerizing contrast in colors arises from a fascinating interplay of densities and origins. Glaciers, immense sculpted ice formations, continuously release freshwater into the Gulf of Alaska.

This water is less dense than the salty ocean water due to the lack of dissolved minerals, creating a temporary layer that flows to the surface. The difference in densities creates a visual distinction, with the glacial water appearing as a lighter or different shade of blue compared to the deeper ocean water. While the oceans don’t have a sharp border where the waters stop mixing, these stunning visuals highlight the ongoing dance between the saltwater and the freshwater.

As oceanographer Dr. Sylvia Earle notes, “The meeting of freshwater and saltwater is a dynamic and beautiful process that illustrates the complexity of our planet’s ecosystems.”
