  • Ocean fertiliser could help plankton trap carbon, but by how much?

    Enhancing the ability of the ocean's phytoplankton bloom to lock away carbon is one proposal in the fight against climate change. A recent study in the Southern Ocean has found that natural sources of iron increase carbon absorption by phytoplankton by two to three times. This suggests that artificial fertilisation with iron could aid carbon removal, but in much lower quantities than predicted by ...

  • Encouraging bacteria to clean up oil spills

    Catastrophic accidents account for 9 per cent of the oil released into marine environments. Several disasters, including the 1989 Exxon Valdez in Alaska, and the Prestige incident, off northern Spain in 2002, have seen the use of 'bioremediation' as part of the clean-up operation. Recent work has investigated combinations of natural additives to increase the speed and efficiency of ...
