Iron fluxes to Talos Dome, Antarctica, over the past 200 kyr

Abstract: Abstract. Atmospheric fluxes of iron (Fe) over the past 200 kyr are reported for the coastal Antarctic Talos Dome ice core, based on acid leachable Fe concentrations. Fluxes of Fe to Talos Dome were consistently greater than those at Dome C, with the greatest difference observed during interglacial climates. We observe different Fe flux trends at Dome C and Talos Dome during the deglaciation and early Holocene, attributed to a combination of deglacial activation of dust sources local to Talos Dome and the reor… Show more

“…Map of dFe concentrations around the Antarctic coastline highlighting McMurdo Sound which is the largest known source of local ASD in the Ross Sea region. Data sourced from ice cores [ Edwards et al ., ; Gaspari et al ., ; Vallelonga et al ., ], aerosols [ Wagener et al ., ], modeling [ Lancelot et al ., ], snow [ Edwards and Sedwick , ; Lannuzel et al ., , ; Loscher et al ., ; van der Merwe et al ., , ; Westerlund and Öhman , ], icebergs [ Raiswell et al ., ], exposed rock (BEDMAP2), and base maps (derived from Qantarctica, Norwegian Polar Institute). Note the difference in method used to extract dFe from ice cores [ Gaspari et al ., ] and coastal snow [e.g., Lannuzel et al ., ].…”

“…[6] Dissolvable Fe concentrations were determined in discrete samples of TD ice sampled for continuous flow analysis [Vallelonga et al., 2013]. For each 1 m long ice sample, 15 mL was collected in Coulter Counter accuvettes at a rate of 0.5 mL/min.…”

“…Episodic changes in mineral dust deposition to the Southern Ocean have been linked to 20th-century climate change and land use modification (Bhattachan and D'Odorico, 2014). Mineral dust proxy records from Antarctic ice cores (Edwards et al, 2006;Gaspari et al, 2006;Spolaor et al, 2012;Vallelonga et al, 2013) and Southern Ocean marine sediments from several regions (e.g. Moore et al, 2000;Martínez-Garcia et al, 2009;Smetacek et al, 2012) display higher deposition rates during glacial stages.…”
