The major threat to the local ecosystem is the hydrogen sulphide, which istoxic to virtually all animal life. Because the leak is below the water's surface, the hydrogen sulphide is bubbling through the sea water. This is the worst-case scenario, says Boxall, because it could lead to mass animal and plant deaths. Boxall says Total needs to monitor the water quality to see if this is happening.

Much of the methane in the water will be consumed by microorganisms andconverted to carbon dioxide. This will make the water slightly more acidic, but the effect will be short-lived and localised, and therefore should not cause too much harm to marine life.

The volatile mix of gases means there is a significant risk of an explosion. As a result, Total have shut down the power supply on the rig, which otherwise might throw a spark. Hogg told New Scientist that the leaking methane posed no safety risks to neighbouring rigs, the nearest of which is the Shearwater rig owned by Shell, about 7 kilometres away.

All three of the escaping gases are greenhouse gases, but unless the leak carries on for weeks or months, the effect on the climate is likely to be small. "The impact on climate change is not going to worry anyone," .

"With wind and atmospheric conditions, the gas disperses and the petrol-like condensate on the surface will disperse quite quickly too,"
