The updated results for 2014 and the preliminary results for 2015 show that the extreme oxygen conditions in the Baltic Proper after the regime shift in 1999 continue. Both the areal extent and the volume with anoxic conditions have, after 1999, been constantly elevated to levels only observed occasionally before the regime shift. Despite the major inflow to the Baltic Sea in December 2014 approximately 16% of the bottom area was affected by anoxia and 29% by hypoxia during 2015.

In Australia -
Dead zones are common in shallow waters where fertilisers and other chemicals trigger algal blooms. They line the coasts of the US, Western Europe and Japan, and there are about 10 known dead zones around Australia’s southern states.

Professor Hoegh-Guldberg says the problem is not as significant in Australia as other parts of the world, but that it is heading along the same, destructive path.

"We've been altering coastal areas, delivering nutrients into the ocean, and of course you see the Great Barrier Reef, which has been quite damaged due to nutrient run-off," he said.

"But the point is that our activities on land have a big influence on what goes on in the oceans and now we are starting to reap the harvest of those changes."

He says the heart and lungs of the planet are being tampered with.

"We are starting to see changes in the ocean's ability to produce oxygen and to produce food and produce all of the ecosystem's services that are so important to not only us, but all of the other organisms on the planet," he said.

"It's mucking around with the heart and lungs of the planet - that's essentially what the oceans are, a huge respiratory system.
