Ocean Survival is Our Survival The oceans are dying . This is not a new thing, it happend several times in the world's history. The causes have differend but one recurring trigger has often been rapid climate change, either warming or cooling. We now experience warming due to CO2 emissions .Frits Rincker has put together some interesting facts and predictions about what may be in store for us. But also has info about oceanographers and other scientists who are working on solutions [no pun intended :-]. Bringing up deep ocean water to fertalise kelp and seaweed production is discussed. I have sent an email to Dr Angelicque White, one of the scientists who has been trying methods of bringing deep water to the surface. by Feb 28

The Southern Ocean is warming faster than the average for the global ocean. Image: Liam Q, Flickr CC-licensed The Antarctic Climate and Ecosystems CRC has launched a synopsis of the latest scientific research into changes in the temperature, salinity, acidity and circulation in the Southern Ocean.
Southern Ocean ‘warming faster’
Ocean acidification is the name given to the ongoing decrease in the pH of the Earth 's oceans , caused by the uptake of anthropogenic carbon dioxide (CO 2 ) from the atmosphere . [ 1 ] About 30–40% of the carbon dioxide released by humans into the atmosphere dissolves into the oceans, rivers and lakes. [ 2 ] [ 3 ] To maintain chemical equilibrium , some of it reacts with the water to form carbonic acid . Some of these extra carbonic acid molecules react with a water molecule to give a bicarbonate ion and a hydronium ion, thus increasing the ocean's " acidity " ( H + ion concentration). Between 1751 and 1994 surface ocean pH is estimated to have decreased from approximately 8.25 to 8.14, [ 4 ] representing an increase of almost 30% in H + ion concentration in the world's oceans. [ 5 ] [ 6 ]

Marine and Atmospheric Research - Our Research
Only 29 percent of the world surface is land. The rest is ocean, home to the marine lifeforms. The oceans average four kilometers in depth and are fringed with coastlines that run for nearly 380,000 kilometres. Marine biology is the scientific study of organisms in the ocean or other marine or brackish bodies of water. Given that in biology many phyla , families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy . Marine biology differs from marine ecology as marine ecology is focused on how organisms interact with each other and the environment, and biology is the study of the organisms themselves.
