一个新的盐沼土壤数据集，包括通过公民科学家支持的采样计划收集的752个土壤样本的地球化学性质和物理性质数据，与现有数据结合在一起，首次对英国盐沼表层(10厘米)土壤有机碳储量进行了全国估计。为了在土壤储量估算中包含二次数据，开发了一种新的针对GB盐沼土壤的定制的有机质到有机碳的转换方法，允许将使用点火损失测量的有机质数据转换为有机碳含量。GB表层土壤有机碳总量为2.320±0.470 Mt，英格兰盐沼为1.601±0.426 Mt，苏格兰盐沼为0.368±0.091 Mt，威尔士盐沼为0.351±0.082 Mt。这些库存是在马尔科夫链蒙特卡罗框架内计算的，这使得第一次能够得出稳健的不确定性估计。在整个英吉利群岛的各个盐沼栖息地，空间测绘工具可用于伴随这些储量估计。这一数据将有助于盐沼的保护和管理，是将盐沼有机碳纳入国家蓝色碳生态系统清单核算的第一步。
A new saltmarsh soil dataset comprising of geochemical and physical property data from 752 soil samples collected through a sampling program supported by citizen scientists has been brought together with existing data to make the first national estimates of the surficial (top 10 cm) soil OC stock for Great British (GB) saltmarshes. To allow the inclusion of secondary data in the soil stock estimate a new bespoke organic matter to organic carbon conversion for GB saltmarsh soil was developed allowing organic matter data measured using loss-on-ignition to be convert to organic carbon content. The total GB surficial soil OC stock is 2.320 ± 0.470 Mt; English saltmarshes hold 1.601 ± 0.426 Mt OC, Scottish saltmarshes hold 0.368 ± 0.091 Mt OC, and Welsh saltmarshes hold 0.351 ± 0.082 Mt OC. The stocks were calculated within a Markov Chain Monte Carlo framework allowing robust uncertainty estimates to be derived for the first time. Spatial mapping tools are available to accompany these stock estimates at individual saltmarsh habitats throughout GB. This data will aid in the protection and management of saltmarshes and represents the first steps towards the inclusion of saltmarsh OC in the national inventory accounting of blue carbon ecosystems.
