Why do the two seas not mix?
We have the Atlantic and Pacific oceans whose melting waters meet at the Alaska coast. The reason for this phenomenon is the difference in density, temperature, and salts of the frozen waters of the Alaskan Gulf, making it difficult to mix.
Ken Bruland, professor of marine science at the University of California-Santa Cruz, was on the trip. He was, in fact, the photographer. He said the purpose of the trip was to explore how great eddies - slow-moving waves - range from hundreds of miles wide, roaming from the Alaskan coast to the Gulf of Alaska.
Those species often carry large quantities of ice because of rivers such as the 280-mile-long [286 km] Copper Alaska River, which is known for its salmon and from the far inland Copper Glacier. It empties east of Prince William Sound, carrying all that heavy clay and soil. And with that sediment comes the metal.
"Summer glaciers are like sawmills eroding mountains," Bruland said. "In practice, they raise the whole thing - they call it glacial flour - which can be made."
When these glaciers flow into the water, they are carried by the ocean currents, eastward and westward, and then around. This is one of the main ways that iron - found in mud and glacial runoff sediment - is transported to iron-free areas in the middle of the Gulf of Alaska. This is one of the most unique gulfs of the world. Pay a trip and visit gulf of Alaska and enjoy the mysterious phenomeno
