During deglaciations, Earth takes up vast amounts of energy, about half of which heats the global ocean. Thus, ocean heat content (OHC) is a key metric to assess Earth's energy budget.
Historical atmospheric H2 levels were reconstructed using firn air measurements from two sites in Greenland (NEEM and Summit) and two sites in Antarctica (South Pole and Megadunes). A joint reconstruction based on the two Antarctic sites yields H2 levels monotonically increasing from about 330?
Invasive alien insects are an important yet understudied component of the general threat that biological invasions pose to biodiversity.
Changes in sea ice conditions and atmospheric circulation over the Southern Ocean play an important role in modulating Antarctic climate. However, observations of both sea ice and wind conditions are limited in Antarctica and the Southern Ocean, both temporally and spatially…
Current interpretation of histological alteration in fish as an indicator of contaminant impact is subjective. Generally severity of alteration is poorly described, and does not allow direct comparison between studies. A histological health index (HHI) modified from Bernet et al (1999)…
We review the 2012 Antarctic ozone hole, making use of various meteorological … reanalyses, remotely sensed ozone measurements and ground-based measurements … of ultra-violet radiation. Based on analysis of 33 years of satellite records…

The Antarctic ozone hole of 2011 is reviewed from a variety of perspectives, making … use of various data and analyses. The ozone hole of 2011 was relatively large … in terms of maximum area, minimum ozone level and total ozone deficit…
The Global Atmosphere Watch of WMO includes several stations in Antarctica that keep a close eye on the ozone … layer during the ozone hole season. Observations made during the ozone holes from 2003 to 2009 will be compared … to each other and interpreted in light of the meteorological conditions.
This work contributes to the understanding of variation in methanesulphonic (MSA) concentration in an ice core … drilled during the 1996-97 Antarctic Campaign at the coastal plateau site of Talos Dome (East Antarctica)…
Firn core methanesulphonic acid (MSA) stratigraphy from Talos Dome (East … Antarctica) was compared with anomalies of the satellite-measured sea ice … extent (1973–1995) in the Ross Sea and Wilkes Land oceanic sector. In spite … of the sparseness of sea ice data…
Australia’s Antarctic territory contains several hydrocarbon-contaminated sites of varying size and severity as a result of fifty years of human activities in the region. Contaminated site remediation in Antarctica is more challenging than in Australia.
Hundreds of thousands of seabirds are killed each year as a result of interacting with longline … and trawl fishing operations, and the severity of the impact varies regionally. Shy and whitecapped … albatrosses, Thalassarche cauta and Thalassarche steadi respectively…
Methanesulphonic acid (MSA) measured along ice cores was largely used as a marker of … past marine biogenic activity because of it is formed by atmospheric oxidation of … dimethylsulphyde (DMS), emitted by metabolic processes of marine biota.
On the surface, the severity of the Antarctic environment is sufficient to account for the injury rates that might occur there. However, it is argued that injury occurrence is the outcome of multiple factors. A number of such factors…
