Stop marine pollution to protect kelp forests
Date:7/17/2013

University of Adelaide marine biologists have found that reducing nutrient pollution in coastal marine environments should help protect kelp forests from the damaging effects of rising CO2.

The researchers have found a combined effect on kelp forests from nutrient pollution and higher CO2, which could have a devastating impact on Australia's marine ecosystems.

"When we manipulated CO2 and nutrient levels in an experimental marine ecosystem we found the effect of both of them together was greater than the sum of their individual impacts," says Dr Bayden Russell, of the University's Environment Institute and Senior Lecturer in the School of Earth and Environmental Sciences.

The project, by PhD student Laura Falkenberg, found that removing the nutrients from the water removed the combined effect, improving the environment for kelp growth.

Kelp forests are one of the most productive marine ecosystems in colder waters and form the basis of food webs for many fish and other marine life. "They are the coral reefs of colder waters," Dr Russell says.

"Increased nutrients from agriculture, wastewater discharge and stormwater on urban coasts are already causing damage to kelp populations in our coastal waters but our research shows that, as CO2 rises the impacts will be much worse and we could lose these really important marine habitats," says Dr Russell.

The researchers grew kelp in experimental tanks floating in the North Haven Boat Harbour with different combinations of added nutrients and CO2. They measured the growth of turf algae which is a precursor to kelp forest loss. As the turf algae grows it displaces the kelp.

"When we removed the nutrients but kept the CO2 high we found that after six months we'd reduced the turf algae by 75% - we'd removed that synergistic effect," says Dr Russell.

"As we face a future of climate change and higher CO2 levels, there is considerable evidence that our mari
