Group Summary

Approved as a SCAR Action Group at the June 2018 SCAR Delegates Meeting in Davos, AntArchitecture aims to develop a continent-wide age-depth model of Antarctica’s ice using the internal layers and surfaces imaged by radar-sounding. The product will underpin the wider goal to determine the stability of the Antarctic Ice Sheets over past glacial cycles, and feeds into additional SCAR Groups such as PAIS, IPICS, and AntClim21.

It has two primary 2-year milestones; the first being production of a white paper for 2020, outlining the need for an Antarctic radar-layers database, the potential applications, and methods for achieving it; the second being the aspiration to publish, in 2022, an online dataset and paper reporting the 3D internal architecture of the Antarctic Ice Sheet. At the time of reporting we are in the final months of achieving milestone 1, and we have made some good progress with efforts towards milestone 2, as will be reported below.

With thanks to the SCAR office, we launched a website in March 2019 which outlines the project in more details, and serves as a forum for communicating our activities and achievements. At the same time we also generated a mailing list for AntArchitecture, which has grown over the past year to 121 subscribers.
