Corrigendum to ‘Environmental magnetism as a tool to reconstruct the historical development of an urban patagonian wetland (Mallín Bahía Serena, Argentina)’ [J. South Am. Earth Sci. 182 (2026) 106197]

Abstract

Urban wetlands provide essential ecosystem services yet are highly vulnerable to city expansion, experiencing accelerated degradation globally. In Argentine Patagonia, mallines—distinctive wetlands characterised by soils with high organic matter content in arid and semi-arid landscapes—deliver key hydrological and ecological functions. However, these systems currently face increasing anthropogenic pressures that threaten their integrity. Despite this, knowledge of their recent environmental history remains limited, as environmental magnetism studies in the region have focused almost exclusively on lacustrine environments, largely overlooking urban- embedded wetlands. In this study, environmental magnetism was applied to reconstruct the historical devel-opment of an urban Patagonian wetland. Magnetic properties (including susceptibility, anhysteretic remanent magnetisation [ARM], and isothermal remanent magnetisation [IRM]), along with lithological descriptions and X-ray radiography, were analysed in short sediment cores retrieved from Mallín Bahía Serena, near San Carlos de Bariloche. The results reveal five distinct developmental stages, which can be grouped into three mail evolu-tionary stages: 1) a moderate-energy basal palaeo-lake (~1170–1390 CE), 2) a transition to a stable wetland environment (~1390–1810 CE), and 3) a top layer reflecting urban deterioration (~1810 CE–present). These findings demonstrate that environmental magnetism is an effective tool for distinguishing natural geogenic signals from those of anthropogenic origin.
