The Mount Brown South ice core (MBS 69.111S 86.312E) is a new, high resolution ice core drilled in coastal East Antarctica. With mean annual accumulation estimated to be ~30 cm ice equivalent throughout the length of the core (~290 m)…
A range of leaching protocols have been used to measure the soluble fraction of aerosol trace elements worldwide, and therefore these measurements may not be directly comparable.
This study presents the first record of trifluoroacetic acid (TFA) in Antarctic ice cores, offering valuable data on TFA and its precursors' long-range atmospheric transport and deposition in remote polar regions. TFA is an ultra-short chain perfluoroalkyl acid (PFAA)…
Antarctic sea ice plays an important role in Southern Ocean biogeochemistry and mediating Earth's climate system. Yet our understanding of biogeochemical cycling in sea ice is limited by the availability of relevant data over sufficient temporal and spatial scales.
Despite widespread iron (Fe) limitation in the Southern Ocean, intense phytoplankton blooms are observed around productive coastal regions such as the Mertz Polynya (off George V Land and Adelie Land, East Antarctica; 140–155°E). Sources of Fe across coastal East Antarctica vary…
The Advisory Committee Work Programme for the 2023 - 2025 triennium was drafted by the Advisory Committee and its Working Groups during its Twelfth Meeting (AC12), held as a virtual meeting, between 31 August and 2 September 2021.
This report to the Seventh Meeting of the Parties has been prepared by the Advisory Committee Chair and Vice-chair with the assistance of the Agreement's Secretariat under Article IX 6 (e).
This report to the Seventh Meeting of the Parties has been drafted as a document in progress for the Advisory Committee by the Chair and Vice-chair with the assistance of the Agreement's Secretariat.
This review of late-Holocene palaeoclimatology represents the results from a PAGES/CLIVAR … Intersection Panel meeting that took place in June 2006. The review is in three parts: the principal high-resolution … proxy disciplines (trees, corals, ice cores and documentary evidence)…
A sodium-form chelating ion-exchange resin, Amberlite IRC-748, and a natural zeolite were investigated … for the exchange of copper and ammonium ions from aqueous solutions at three temperatures ((4.0, 20.0, and 40.0) ( 0.2) °C. Maximum exchange capacities were determined…
Electromagnetic ion cyclotron (EMIC) waves are generated in the equatorial … region of the plasmasphere-magnetospherbey internal wave-particle interaction … with ring current ions. In ground observations they are observed as Pc 1-2 (0.1-5 … Hz) waves…
Selenium is an essential micronutrient but its role in oceanic biology is relatively unknown. Whilst this essentiality has been shown in laboratory work for some marine phytoplankton … species, the concentration, chemical species and incorporation methods are unknown.
Around 145 different non-marine algae have been identified from the Windmill Islands region, Antarctica. About 24 of these occur in the snow. Nearly half of these, which includes all the dominant snow algae, complete their life cycles in the snow and do not grow elsewhere.
In recent times there has been increasing interest in Sr as an isotopic tracer in environmental … studies. There is the potential to characterise dust inputs at a certain site by transport of … material from source areas if the isotopic compositions of the site and source areas are … known.
Antarctic ice is an archive of evidence of climatic conditions and natural phenomena in the … Southern Hemisphere that extends approximately one million years into the past. We can … sense changes through the concentration of atmospheric gases, stable isotope ratios, terrestrial dust levels…
