OCEANOGRAPHY FINAL Darius Owens Group 3. Lakes within the oceans (Brine Lakes); explain what is being talked about here: Underwater lakes that is as salty as the Great Salt Lake in Utah. Brine is water that is has an extremely high concentration of salt (NaCl), higher than that of normal seawater. http://www.environmentalgraffiti.com/featured/lakes650ft-beneath-the-waves/2413? image=1 What are these lakes? Brine lakes are salty lakes that are denser than ocean water and settle to the bottom. They’re mixed with hydrogen, methane, and other chemicals. They contain little oxygen and they are generally warmer than the water above them, sometimes being up to 20 degrees warmer. http://www.scienceandthesea.org/index.php? Where are they found? They are usually found in the Gulf of Mexico and the Yucatan peninsula. http://www.scienceandthesea.org/index.php? How do they form? It is produced through salt tectonics, or the movement of large salt deposits.

Fish, crabs, or other large creatures cannot live in these conditions. However, researchers have found large colonies of microbes. Matter a fact, some brine pools have at least a hundred times more microbes than the water layers around them. Sometimes, mussels surround these lakes and feed on them. http://www.scienceandthesea.org/index.php? option=com_content&task=view&id=339&Itemid=10 What makes them so interesting? Despite the fact that there is barely any oxygen and that many creatures we associate with the sea do not live there, life still managed to find a way to thrive in such a hostile environment within the waters....
