Radar isochrones of Antarctica, in one database
The AntADatabase gathers the published internal reflecting horizons (IRHs, or isochrones) traced in ice-penetrating radar data across Antarctica, with their ages, in one uniform format. It is built for ice sheet modellers and glaciologists who need consistent, dated layers to constrain their models, and grows as new datasets of the AntArchitecture community are published.

The anta_database package: query the isochrones by dataset, institute, age, region or basin,
plot them on maps and along flight lines, and load them into your own analysis.
Download the data
Free to download. We recommend the Python package, which downloads the whole database and keeps it up to date. You can also choose datasets in the catalogue and get them in one zip file.
