An interactive map detailing Antarctic ice cover has been developed to assist researchers and navigators working along the continent’s coastline. This initiative is part of the broader efforts of the Australian Antarctic Program to support safe travel and scientific work in polar waters.

The map, named Nilas, blends live observations with historical records. It integrates current sea-ice concentrations with data on chlorophyll levels, a proxy for phytoplankton activity, and sea-surface temperatures. Historical ice data from 1980 and chlorophyll data from 1998 are used to enrich the context and enable more robust analysis.

Researchers believe that combining archive data with real-time measurements—along with the ability to overlay past or estimated ship routes, animal movement, or instrument performance on this dataset—offers a potent tool for planning, analysis, and discovery. The team outlined a marine expedition where the map would guide the placement of instruments designed to monitor ice-breaking dynamics at the land-sea interface. It also helped determine the most favorable window for fieldwork, identifying periods when vessel risk would be lowest.

Beyond practical navigation and logistics, the model holds promise for revealing complex links in the natural world. For example, phytoplankton activity can influence atmospheric composition through sulfate aerosols, a factor that underscores the value of having integrated information in a single interface for interdisciplinary research.
