“…It has likely been caused by BC emitted from forest fires, which took place in the Argentinian province Chubut (Patagonia) between mid-February and the beginning of April 2015, i.e., at the time of the Calbuco eruption. Both forest fires, in Torres del Paine in 2011/12 and in Argentinian Patagonia in 2015, are among the most devastating forest fires documented in these regions [76][77][78] and hence, are likely to have left an imprint on the LCL ice cap. However, other BC sources than biomass burning such as industrial emissions cannot be ruled out to have contributed to the deposition of BC on the LCL ice cap.…”

Short-Term Meteorological and Environmental Signals Recorded in a Firn Core from a High-Accumulation Site on Plateau Laclavere, Antarctic Peninsula

High-accumulation sites are crucial for understanding the patterns and mechanisms of climate and environmental change in Antarctica since they allow gaining high-resolution proxy records from firn and ice. Here, we present new glacio- and isotope-geochemical data at sub-annual resolution from a firn core retrieved from an ice cap on Plateau Laclavere (LCL), northern Antarctic Peninsula, covering the period 2012–2015. The signals of two volcanic eruptions and two forest fire events in South America could be identified in the non-sea-salt sulphur and black carbon records, respectively. Mean annual snow accumulation on LCL amounts to 2500 kg m−2 a−1 and exhibits low inter-annual variability. Time series of δ18O, δD and d excess show no seasonal cyclicity, which may result from (1) a reduced annual temperature amplitude due to the maritime climate and (2) post-depositional processes. The firn core stratigraphy indicates strong surface melt on LCL during austral summers 2013 and 2015, likely related to large-scale warm-air advection from lower latitudes and temporal variations in sea ice extent in the Bellingshausen-Amundsen Sea. The LCL ice cap is a highly valuable natural archive since it captures regional meteorological and environmental signals as well as their connection to the South American continent.
