Conventionally the source of sea salt in the Antarctica was considered to be the ocean … surface. In simple terms, sea salt is ejected into the atmosphere as sea spray droplets, mixed … in the atmosphere, and transported to Antarctica via storm activity. Recently, however…
Abstract. The discovery of an abundance of microorganisms that flourish in a diverse range of environments, from the frigid waters of the Antarctic, to the superheated waters of the hydrothermal vents, at the bottom of 11-km … deep ocean trenches and in salt-saturated lakes…
Measuring the geo-electric field becomes important in understanding the global electric circuit and how it is affected by other phenomena. It is also useful in assessing how the global electric circuit variations can affect climate.
Polar organisms have adapted their seasonal cycles to the dynamic interface between ice and water. This interface ranges from the micrometre-sized brine channels within sea ice to the planetary-scale advance and retreat of sea ice.
Muon observations are complementary to neutron monitor … observations but there are some important differences in the two techniques. Unlike neutron monitors, muon telescope systems use coincidence techniques to obtain directional information about the arriving particle.
The Antarctic Pack-Ice Seals program (APIS) is an initiative of the SCAR Expert Group on Seals aimed at quantifying the role of pack-ice seals (crabeater, leopard and Ross) in the Southern Ocean. A central feature of APIS was a synoptic…

Bycatch of seabirds during longline fishing operations is listed under Australian legislation as a key threatening process which could endanger 14 species of seabirds. In 1998 a Threat Abatement Plan (TAP) was finalised to manage this threat.
This book is the outcome of 132 interviews with women who have lived and worked in Antarctica. It examines their reasons for going there, the work that they undertake, their experiences of community life with its opportunities and challenges…
Monitoring CO2 isotopes at Cape Grim commenced in 1976 (Goodman, 1980), using CO2 extracted from the air and returned to Aspendale for mass spectrometer analysis. The objective was to distinguish between terrestrial (including biosphere exchanges, deforestation and fossil fuel emissions)…
The paper gives an overview of the legal regime in relation to the marine living resources in the maritime zones adjacent to the Australian Antarctic Territory and the Territory of Heard island and the McDonald Islands. It also raises some international legal issues…
Fifty-two echinoderm species are recorded from off Macquarie Island and the Macquarie Ridge in the Southern Ocean. One new asteroid Odontohenricia anarea sp. nov. and one new holothurian Trachythyone nelladana sp. nov. are described. The asteroid genus Calvasterias is synonymised with Anasterias.
Infrared astronomy has made remarkable progress over the past quarter century. This paper, which is a brief summary of the 1999 Ellery Lecture, outlines the importance of … the infrared, traces some of the key Australian developments in the field…
The study reported here invesitgates the practice og science in a particular institution. It examines the actual positions, politics and epistemology og women scientsts within the Australian National Antarctic Research Expeditions. With a focus on their narratives…
This paper focusses on three methdological issues arising from the research: the impact of the subject position of the researcher in data gathering and interpretation; ethical aspects of the relationships between the researcher and the researched especially in participant observation…
A new Holocene sea-level record from the Vestfold Hills, Antarctica, has been obtained by dating the lacustrine-marine and marine-lacustrine transitions that occur in sediment cores from lakes which were formerly connected to the sea. From an elevation of similar to 7.5 m 8000 years ago…
