Cover Story: The reconstruction of 71 ka of atmospheric Hg deposition from a remote peatland in Easter Island showed the role of natural processes in local Hg accumulation. This paper is a good example of how climate (both precipitation and temperature) has controlled abrupt changes in Hg accumulation. Other processes, such as mire vegetation, peat decomposition, aeolian dust, oceanic evasion, and volcanic activity may have played a secondary role in Hg content. The combinations of all these processes caused a 28-fold range of variation in Hg concentrations in a remote and undisturbed area. Our maximum values are higher than those recorded in most peat records belonging to the Industrial Period, highlighting that natural factors played a significant role in local Hg accumulation—sometimes even more so than anthropogenic sources.
