Abstract

The structure of marine ecosystems, and associated biogeochemical cycles, will be affected by climate change and increased human activity. Marine phytoplankton produce a wide range of trace gases, and it has been suggested these gases play a role in controlling atmospheric chemistry. Bromocarbons — produced by diatoms — are released to the atmosphere as inorganic bromine, which interacts with ozone and dimethyl sulphide, and has a role in cloud formation. Climate-induced changes in phytoplankton composition could lead to altered gas release to the atmosphere.
