Free art from oil

Tate Modern was forced to close down parts of its No Soul For Sale tenth anniversary exhibition on Saturday (15 May) whilst it struggled to remove dozens of dead fish and oil-soaked birds hanging from huge black balloons let loose in the Turbine Hall.

Scientists have raised urgent new concerns over the latest efforts to mitigate the catastrophic oil spill in the Gulf of Mexico caused by the oil rig explosion on BP's Deepwater Horizon. Latest efforts to limit the environmental damage involve an untried deep-water technique, using a toxic dispersant that they believe may damage ocean life.

Scientists said they had found vast underwater plumes of oil, one 10 miles (16km) long and a mile wide. Researchers from the National Institute for Undersea Science and Technology said they had detected the slicks lurking just beneath the surface of the sea and at depths of 4,000ft (1,200m). Chemical dispersants BP has been dumping underwater may be preventing the oil from rising to the top of the ocean, the scientists said. The find suggests the scale of the potential environmental disaster is much worse than previously feared since the Deepwater Horizon drilling rig blew up on 20 April, killing 11 workers.

To celebrate Tate Modern's 10th birthday, our readers put their questions to its director, Nicholas Serota

"In a time of climate change, will you stop sponsorship by oil companies so we can visit Tate and enjoy great art without being complicit in climate chaos?"

Nicholas Serota replies... "The first thing to say is we have support from BP, which as a company is looking at renewable energy as well as using up fossil fuels and using oil. We have long had support from them and are not intending to abandon it."
