Atmospheric Particle Number Concentrations and New Particle Formation over the Southern Ocean and Antarctica: A Critical Review by Jiayu Wang, Guojie Xu, Liqi Chen, Kui Chen

By summarizing the research progress over the SO and Antarctica, we discuss possible precursors of the NPF: sulfuric acid (H₂SO₄, SA), methanesulfonic acid (CH₃S(O)₂OH, MSA), dimethyl sulfide ((CH₃)₂S, DMS), iodic acid (HIO₃, IA), iodous acid (HIO₂), ammonia (NH₃), dimethylamine ((CH₃)₂NH, DMA), highly oxygenated organic molecules (HOMs) and other organics with low vapor pressure. …”

“…Three different approaches are recommended for post-fire land management: 1) farmers should not cut and remove the weeds and grasses at the soil surface, 2) burning should be performed around late winter or early summer (November–February) to inhibit complete combustion, and 3) contour-felled log erosion barriers should be made by using the trunks remaining after the fire to trap the sediment and slow down surface runoff.…”

Quantifying the role of iron recycling by Adélie and Emperor penguins over the austral spring and summer in Prydz Bay by Lavenia Ratnarajah, Lavenia Ratnarajah, Louise Emmerson, Colin Southwell, Delphine Lannuzel, Ashley T. Townsend, Andrew R. Bowie, Andrew R. Bowie

“…Breeding emperor penguins supplied an average of 237 μmol iron m−2 day−1 on the fast ice that they breed on that eventually ends in the ocean when the ice melts completely in summer (November–February). During their foraging trips, the adult emperor penguins contribute between 7 × 10−5 and 4 × 10−4 μmol iron m−2 day−1, as their foraging ranges increase over the breeding season. …”
