Across a range of genres, and from multiple sources, we have explored the main themes of specific science fiction works and how they contribute to public discourse on the Antarctic. In this case we have defined science fiction as aspirational perspectives of the future from any point in time. Selected works have been examined through multiple readings using a shortened form of critical discourse analysis. The results are ordered around a simple analytical framework in which the main themes can be summarized as Political (global, scientific, personal identity); Economic (mining, tourism, science); Social (heroism); Technological (various innovations and research itself); Legal (often conspicuous by its absence); and Environmental (global change processes). Examining these as an ensemble of themes we conclude that the science fiction genre is largely one of hidden shallows with occasional great depths. Furthermore, it is important as much for what it excludes from public debate, rather than its insights alone. We have also represented our work through a performative work in the science fiction genre.
