The striking images on these stamps are colour enhanced scanning electron microscope (SEM) photographs of four diatom species found in Antarctica. Diatoms are one of the most abundant and diverse groups of photosynthetic algae. That means they use sunlight, water and carbon dioxide to make their own food (glucose) and emit oxygen. As oxygen producers, diatoms are more important than all the rainforests, generating 20-50 % of the oxygen we breathe. Diatoms occur in virtually every aquatic and sub-aquatic environment, anywhere there is sufficient moisture (fresh or saline) and sunlight for photosynthesis. They are also a primary food source, contributing up to 40% of the global oceans primary production and feeding higher organisms across nearly all marine and freshwater habitats.

The global population of southern giant petrels (Macronectes giganteus) is around 50,000 pairs. They are the top avian predator in the Antarctic. This is one of the most sexually size-dimorphic of all seabirds, with males around 20% larger than females and with much more robust bills. Both sexes will feed at sea, sometimes travelling >1000 km from colonies but male giant petrels in particular also target penguin chicks and adults around their colonies, and fight over seal and other carrion on land. Old-time whalers used to call them ‘breakbones’ or ‘stinkers’ because of their frequent blood-stained brawls over carrion meat.
