During a cruise from Hamburg to Montevideo, aerosol samples representing air masses from Europe, the Sahara, tropical Africa, South America, and open oceanic regions were collected. They showed significant amounts of soot carbon over large areas of the remote Atlantic, often similar to concentrations in rural continental areas. Back-trajectories and the ratios of soot carbon to total fine (less than 1.7 micrometers in diameter) carbon and of excess fine potassium (the portion not attributable to soil dust or sea salt) to soot carbon indicate that biomass burning in tropical regions is an important source of soot carbon to the world atmosphere. The ratio of excess potassium to soot carbon in the fine fraction of aerosols is proposed as an indicator of the relative contributions of biomass and fossil-fuel burning to soot carbon aerosols. The ratio of soot carbon to fine carbon suggests that most of the particulate organic carbon over the Atlantic is of continental origin.
在从汉堡到蒙得维的亚的巡游过程中，采集了代表来自欧洲、撒哈拉、热带非洲、南美洲和开阔海洋区域空气团的气溶胶样本。结果表明，在偏远的大西洋大片区域存在大量的烟尘碳，其浓度通常与农村大陆地区相似。后向轨迹以及烟尘碳与总细碳（直径小于 1.7 微米）的比值，以及过量细钾（无法归因于土壤尘埃或海盐的部分）与烟尘碳的比值表明，热带地区的生物质燃烧是世界大气中烟尘碳的一个重要来源。气溶胶细颗粒中过量钾与烟尘碳的比值被提议作为生物质和化石燃料燃烧对烟尘碳气溶胶相对贡献的指示。烟尘碳与细碳的比值表明，大西洋上的大部分颗粒有机碳都来自大陆。
