مرج البحرين يلتقيان- صورة بتاخذ العقل سبحان الله

This Photo express the margins between oceans water. No one interfere the other. it's really amazing. The two seas or oceans are made to flow freely (so that) they meet together, Between them is a barrier which they cannot pass.

A picture from the Gulf of Alaska that has been making the rounds on the Internet for the last few years shows a strange natural phenomenon that occurs when heavy, sediment-laden water from glacial valleys and rivers pours into the open ocean. There in the gulf, the two types of water run into each other, a light, almost electric blue merging with a darker slate-blue.

 

Ken Bruland, professor of ocean sciences at University of California-Santa Cruz, was on that cruise. In fact, he was the one who snapped the pic. He said the purpose of the cruise was to examine how huge eddies -- slow moving currents -- ranging into the hundreds of kilometers in diameter, swirl out from the Alaska coast into the Gulf of Alaska.

 

Photographer Kent Smith snapped this photo of glacial waters from Alaska rivers merging with the darker blue waters of the Gulf of Alaska while on a cruise on July 10, 2010.

 

Boundary between coastal waters influenced by glacial weathering (light blue) and offshore waters of the Gulf of Alaska (darker blue).

 

As for that specific photo, Bruland said that it shows the plume of water pouring out from one of these sediment-rich rivers and meeting with the general ocean water. It’s also a falsehood that these two types of water don’t mix at all, he said.

 

Ocean margins are the transitional zones between the oceans and continents. They represent dynamic systems in which numerous processes shape the environment and result in an impacting the utilization and hazard potentials for humans. These processes are influenced by a variety of steering mechanisms, from mountain building and climate on the land to tectonics and sea-level fluctuations in ocean margins . This book examines various aspects of regulation for the long-term development of ocean margins, of the impact of fluids and of the dynamics of benthic life at and below the seafloor in ocean margin systems.
