Abstract
This work was in part funded by the Icelandic Research Fund (Rannis) Grant No. 152248-051; by the Czech Science Foundation project GC16-14122J and projects no. LM2015078, CZ.02.1.01/0.0/0.0/16_013/0001708; and the Masaryk University project MUNI/A/1251/2017. The LOAC instruments were funded by the French Labex VOLTAIRE. Field work was carried out with help of staff of the Johann Gregor Mendel Station.
Highlights
Antarctica is the largest polar desert in the world, of which approximately 2% of its surface area is ice-free and contains active High Latitude Dust sources (HLD, Bullard et al, 2016)
A mean PM10 value of 6.4 μg m−3 from the Antarctic Peninsula is comparable to two stations in Norway, but higher than the annual mean of 4.4 μg m−3 in Sevettijarvi, Finland (Putaud et al, 2010)
Most of the research on aeolian processes are concentrated to a few areas – the McMurdo Dry Valleys (e.g., Lancaster, 2002; Fortner et al, 2011; Šabacká et al, 2012), the Antarctic Peninsula (e.g., Artaxo and Rabello, 1992; Asmi et al, 2018), or at the edge of the continent (e.g., Weller et al, 2008; Chaubey et al, 2011; Budhavant et al, 2015)
Summary
Antarctica is the largest polar desert in the world, of which approximately 2% of its surface area is ice-free and contains active High Latitude Dust sources (HLD, Bullard et al, 2016) It is the coldest, windiest (maximum speed of 90 m s−1) and driest continent, with annual precipitation reaching approximately 300 mm in the coastal areas (King and Turner, 1997; van Lipzig et al, 2004). Aeolian processes acting in high latitudes develop a specific range of surface landforms, such as ripples or smallscale dunes These landforms are spatially restricted to areas with low surface moisture contents and an absence of vegetation cover (Bullard et al, 2016). In periglacial environments where glaciers have recently receded and left large amounts of unsorted
