Preconcentration method for electrothermal atomic absorption spectrometric analysis for heavy metals in Antarctic snow at sub ng kg−1 levels

1 March, 1992 by Eric Wolff

An improved technique for concentrating heavy metals onto the surface of tungsten wires, prior to analysis by electrothermal atomic absorption spectrometry, is reported. Ultraclean methods and materials, described here, have…

The effect of sample emission on measurements of spectral parameters using a fourier transform absorption spectrometer

1 January, 1992 by Howard Roscoe

Radiative transfer within an interferometric spectrometer is discussed in relation to measurements of infrared transmittance spectra of gases. It is shown that for certain types of interferometric spectrometers, radiation from…

Distributions and predator-prey interactions of macaroni penguins, Antarctic fur seals, and Antarctic krill near Bird Island, South Georgia

1 January, 1992

We studied the distributions, abundances and interactions of macaroni penguins Eudyptes chrysolophus, Antarchc fur seals Arctocephalus gazella, and their zooplankton prey, m particular Antarctic krill Euphausia superba, near Bird Island,…

The use of a simultaneous physical retrieval scheme for satellite derived atmospheric temperatures: Weddell Sea, Antarctica

1 January, 1992 by Thomas Lachlan-Cope

Atmospheric temperature retrievals obtained by a simultaneous physical scheme and a statistical scheme are compared using data gathered over the Weddell Sea, Antarctica during January 1986. Ground truth data were…
