Abstract

It is well known that iron fertilization can increase primary production and hence CO 2 drawdown over a significant fraction of the oceans. What is less well established is the extent to which this leads to long-term sequestration of carbon to the deep oceans, and to feedbacks to the atmosphere arising from increased biological activity. In this note results for changes in trace gas concentrations during an iron addition experiment in the Southern Ocean are presented. They demonstrate that a complex situation exists; some gases (DMS, CH 3 I, CHBr 2 Cl) show increases in concentration following fertilization with iron while others show no change (CH 3 ONO 2 , CH 2 ClI) or even a decrease (CHBr 3 ). The concomitant effects on air–sea fluxes of these gases are potentially important for climate and atmospheric composition. DOI: 10.1111/j.1600-0889.2005.00141.x

含铁的海洋施肥:对气候和空气质量的影响

众所周知，铁肥可以增加初级产量，从而在很大一部分海洋上减少二氧化碳。不太确定的是，这在多大程度上导致了碳在深海的长期封存，以及在多大程度上导致了生物活动增加对大气的反馈。本文介绍了在南大洋进行加铁实验期间微量气体浓度变化的结果。它们表明存在着复杂的情况;一些气体(DMS, ch3i, chbr2cl)在铁施肥后浓度增加，而其他气体(ch3ono 2, ch2cli)没有变化，甚至减少(chbr3)。这些气体对海气通量的伴随影响对气候和大气组成具有潜在的重要意义。DOI: 10.1111 / j.1600-0889.2005.00141.x

期刊介绍： Tellus B: Chemical and Physical Meteorology along with its sister journal Tellus A: Dynamic Meteorology and Oceanography, are the international, peer-reviewed journals of the International Meteorological Institute in Stockholm, an independent non-for-profit body integrated into the Department of Meteorology at the Faculty of Sciences of Stockholm University, Sweden. Aiming to promote the exchange of knowledge about meteorology from across a range of scientific sub-disciplines, the two journals serve an international community of researchers, policy makers, managers, media and the general public.
