Antarctic sciences are progressing through the increasing use of remote sensing data, data compilations,
and geophysical models that rely on visualisations, for example coloured contour maps, as the key medium
of knowledge discovery. Such data-driven approaches benefit from careful attention to 'visual literacy' in
parallel with good written or spoken communication. Antarctic research has a more frequent need for good
management of resolution changes, data gaps and uncertainty than is common for other continents.
Using a recently published software suite that enables researchers to make well-posed colour choices, we
present a set of colour maps that are suited to the display of Antarctic geophysics data and models. These
colour maps consider human perception, and hence maximise the chance of feature discovery within a
given datasets, and also minimise the possibility of a mistaken inference due to artefacts of the display
process. We also show some workflows that provide an exemplar of the use enhanced graphics capability
such as opacity that enable the better management of patchy coverage. We also provide exemplars of
visualisation techniques and colour optimisation for rapid display and exploration of volumetric data.
We hope that our colourmaps will find wide usage within Antarctic Sciences, and related disciplines. We
also anticipate that wider use of enhanced capability with opacity will help researchers to progress
knowledge discovery, finding insights from their data, in the case of resolution challenges and analysis of
multiple datasets that are commonly encountered in Antarctic research.
