Dimethyl sulphide (DMS) and carbon monoxide (CO) are climate-relevant trace gases that play key roles in the radiative budget of the Arctic atmosphere. Under global warming, Arctic sea ice retreats at an unprecedented rate, altering light penetration and biological communities, and potentially affect DMS and CO cycling in the Arctic Ocean. This could have socio-economic implications in and beyond the Arctic region. However, little is known about CO production pathways and emissions in this region and the future development of DMS and CO cycling. Here we summarize the current understanding and assess potential future changes of DMS and CO cycling in relation to changes in sea ice coverage, light penetration, bacterial and microalgal communities, pH and physical properties. We suggest that production of DMS and CO might increase with ice melting, increasing light availability and shifting phytoplankton community. Among others, policy measures should facilitate large-scale process studies, coordinated long term observations and modelling efforts to improve our current understanding of the cycling and emissions of DMS and CO in the Arctic Ocean and of global consequences.

不断变化的北冰洋和气候对二甲基硫和一氧化碳的生物地球化学循环的作用

二甲基硫 (DMS) 和一氧化碳 (CO) 是与气候相关的微量气体,在北极大气的辐射收支中发挥着关键作用。在全球变暖的情况下,北极海冰以前所未有的速度消退,改变了光的穿透性和生物群落,并可能影响北冰洋的 DMS 和 CO 循环。这可能会对北极地区内外的社会经济产生影响。然而,关于该地区二氧化碳的产生途径和排放,以及 DMS 和二氧化碳循环的未来发展,人们知之甚少。在这里,我们总结了当前的理解并评估了 DMS 和 CO 循环与海冰覆盖、光穿透、细菌和微藻群落、pH 和物理特性的变化相关的潜在未来变化。我们建议 DMS 和 CO 的产生可能会随着冰融化而增加,增加光照和改变浮游植物群落。除其他外,政策措施应促进大规模过程研究、协调长期观测和建模工作,以提高我们目前对北冰洋 DMS 和 CO 的循环和排放以及全球后果的理解。
