Monitoring of background atmospheric CO2 concentration in recent decades has revealed interannual growth rate variations (IAV) that are linked to the El Nino Southern Oscillation (ENSO). However, the nature of this link is not well understood.
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)…
We are using techniques of molecular genetics to investigate the extent of genetic diversity in Antarctic mosses. The RAPD technique has proven especially useful in demonstrating that these mosses exhibit extensive genetic variation (levels being similar to those in temperate regions)…
The SAZ project organised by the Antarctic CRC has a continuing program of moored sinking particle trap studies in the Sub-Antarctic and Polar Frontal zones southwest of Tasmania along 140 °E.
ABSTRACT. The exploration of eastern Prydz Bay, East Antarctica, is discussed using temporally and spatially increasing information on the distribution (and size) of Adélie penguin Pygoscelis adeliae colonies as an index of activities undertaken by various nations there.
