Category 3: Conference paper

In recent years there has been increasing pressure at the international level to improve environmental management in the Antarctic. The Protocol on Environmental Protection to the Antarctic Treaty (the Madrid Protocol)…

Community structure and psychrophily in Antarctic ecosystems Microbial Biosystems: New Frontiers, Proceedings of the 8th International Symposium on Microbial Ecology, Halifax, Canada, 2000 (Ref: 9879)
Category 3: Poster

Molecular based and traditional microbiological techniques were utilized to determine thestructure and degree of cold adaptation of a variety of Antarctic bacterial communities.

Phylogenetic diversity of picocyanobacteria in Arctic and Antarctic ecosystems Microbial Biosystems: New Frontiers, Proceedings of the 8th International Symposium on Microbial Ecology, Halifax Canada, 2000 (Ref: 9878)
Category 3: Conference paper

Oxyphotobacteria ascribed to the genera Synechococcus and Synechocystis are widely distributed in Arctic and Antarctic lakes, yet they are poorly represented in the marine polar environment. Arctic lakes contain phycoerythrin-rich as well as phycocyanin-rich … picoplankton…

Importance of "Historic Sites" on Heard Island for Protection of Scientific Resources and Environmental Management of a World Heritage Site Papers and Proceedings of the Royal Society of Tasmania,, 2000 (Ref: 9340)
Category 3: Conference paper

Heard Island has important historic sites relating ot hte hnting of elephant seals and various scientific activities, which are noted in the Workd Heritage citation for the island. Some, especially sealing sites, are generally acknoweldged to have historic value, but the value of later sites…

Ten Myths about the preservation of historic sites in Antarctica and some implications for Mawson's Huts at Cape Denison Polar Record., 2000 (Ref: 8905)
Authors:
Category 1: Peer-reviewed literature

A review of popular writing on the subject of preservation of historic sites in Antarctica, including buildings, graves and artefacts, has revealed many misconceptions about the existence and cause of deterioration problems.

Infrared astronomy. In the heat of the night. The 1999 Ellery Lecture. Publications of the Astronomical Society of Australia, 2000 (Ref: 9623)
Authors:
Category 1: Peer-reviewed literature

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…

Mid-Infrared Observing Conditions at the South Pole Astrophysical Journal, 2000 (Ref: 9858)
Category 1: Peer-reviewed literature

Measurements of the mid-infrared sky brightness at the South Pole throughout the winter of 1998 show that the sky background is … extremely low and stable. For 50% of the time, the flux in the 8.78 to 9.09 ?m window is below 50 Jy per square arcsecond.

Novel instruments for site characterization Proceedings SPIE, 2000 (Ref: 9621)
Category 3: Conference paper

In order to fully characterize the astronomical potential of remote sites on the antarctic plateau, we have developed a suite of instruments covering UV to sub-millimeter … wavelengths. In addition…

Science goals for an Antarctic large infrared telescope Proceedings SPIE, 2000 (Ref: 9622)
Category 3: Conference paper

Over the past few years, site-testing at the South Pole has revealed conditions that are uniquely favorable for IR astronomy. In particular…

A shipboard method for arsenic speciation using semi-automated hydride generation atomic fluorescence spectroscopy Analytica Chimica Acta, 2000 (Ref: 9185)
Category 1: Peer-reviewed literature

The development of a semi-automated batch HG-AFS method for the shipboard determination of As(III), As(V), MMA and DMA is described. Procedures in the analytical sequence including addition of NaBH4 to samples, cooling and heating the U-trap used for preconcentration and separation of the arsines…

Genetic diversity, colonisation and dispersal of mosses in the Ross Sea Region of Antarctica. Antarctic Ecosystems: Models for Wider Ecological Understanding, 2000 (Ref: 8416)
Category 1: Peer-reviewed literature

We are using molecular genetics techniques to investigate (a) the overall level of genetic diversity in Antarctic mosses, (b) the spatial arrangement and mutation levels within populations, (c) their taxonomic relationships and origins, (d) the effect of climate change on mutation levels, and (e)…

Antarctic bryophytes and global climate change: Surface reflectance of Antarctic bryophytes and protection from UV and visible light. Abstracts of the COMBIO 2000 conference, 2000 (Ref: 10166)
Category 3: Conference paper

As well as determining the amount of solar radiation available for photosynthesis, the surface reflectance and absorptance characteristics of plants are their first defence against damaging effects of solar radiation. The solar spectrum can be damaging to plants in many ways. At shorter wavelengths…
