海洋生态系统的结构以及相关的生物地球化学循环将受到气候变化和人类活动增加的影响。海洋浮游植物产生多种微量气体，有人认为这些气体在控制大气化学方面发挥着作用。由硅藻产生的溴碳以无机溴的形式释放到大气中，与臭氧和二甲硫醚相互作用，并在云的形成中发挥作用。气候引起的浮游植物成分变化可能导致向大气中释放的气体发生变化。东安格利亚大学的克莱尔·休斯(Claire Hughes)及其同事测量了沿海水域和南极半岛西部大气中的生物溴碳和生物参数。采样涵盖了多年来的所有季节。
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.Claire Hughes, from the University of East Anglia, and colleagues, measured biogenic bromocarbons and biological parameters in coastal waters and the atmosphere of the western Antarctic Peninsula. The sampling encompassed all seasons over a number of years.
