Sea‐salt aerosol in coastal Antarctic regions [PDF]
Journal of Geophysical Research: Atmospheres, 1998 Continuous year round records of atmospheric sea‐salt concentrations have been recovered at three coastal Antarctic stations (Halley, Dumont D'Urville, and Neumayer) at temporal resolutions typically between 1 day and 2 weeks. The records were evaluated in terms of their spatial and seasonal variability as well as with respect to changes in the ...

Evidence for strong environmental control on bacterial microbiomes of Antarctic springtails
Scientific Reports, 2021 Collembola are a key component of the soil biota globally, playing an important role in community and ecosystem dynamics. Equally significant are their associated microbiomes, that can contribute to key metabolic functions.

Multidecadal warming of Antarctic waters [PDF]
, 2014 Decadal trends in the properties of seawater adjacent to Antarctica are poorly known, and the mechanisms responsible for such changes are uncertain. Antarctic ice sheet mass loss is largely driven by ice shelf basal melt, which is influenced by ocean-ice

Genetic population structure in the Antarctic benthos: insights from the widespread amphipod, Orchomenella franklini. [PDF]
PLoS ONE, 2012 Currently there is very limited understanding of genetic population structure in the Antarctic benthos. We conducted one of the first studies of microsatellite variation in an Antarctic benthic invertebrate, using the ubiquitous amphipod Orchomenella ...

Ice core evidence for a second volcanic eruption around 1809 in the Northern Hemisphere [PDF]
, 2006 A volcanic signal observed in ice cores from both polar regions six years prior to Tambora is attributed to an unknown tropical eruption in 1809. Recovery of dacitic tephra from the 1809 horizon in a Yukon ice core (Eclipse) that is chemically distinct ...
