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.
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…
Over the past few years, site-testing at the South Pole has revealed conditions that are uniquely favorable for IR astronomy. In particular…
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…
Bryophytes (mosses and liverworts) are sensitive indicators of environmental change and with climate change expected to occur first at high latitudes, Antarctic bryophytes are ideal study systems for the detection of climate change effects.
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…
We studied sexual and individual differences in foraging and parental behavior of King Cormorants (Phalacrocorax albiventer) rearing chicks were studied at subantarctic Macquarie Island. Females dived mainly in the morning and males in the afternoon. Five females were shallow divers (1.9 to 6.8 m)…
