Developing AIDMAP: A roadmap to interactive community-based data compilation for magnetic data in Antarctica.

Antarctica poses a unique challenge for data compilation and sharing, due to the sourcing of data from many national programs and a diversity of surveys and data access protocols. Coordinated by the Scientific Committee on Antarctic Research, the Antarctic Digital Magnetic Anomaly Project (ADMAP) has made huge progress to collate coordinate and disseminate the magnetic data of Antarctica. ADMAP’s first iteration was produced in 2001, and the second iteration was released in 2018. The community is looking now towards the next iteration to support ongoing research in Antarctica. We present here a roadmap for this data compilation, with a focus on the ability for researchers to access a live and interactive resource, to add new data when it is available, and for this to be realised in the compilation soon after data submission. For this it is necessary to ease the burden of data processing, to define a consistent approach to the data handling, and to accelerate the timeline from data-submission to incorporation into the compilation. The approach therefore is founded on an automated data-processing workflow that can accommodate the wide variety of data submitted (variable spacings, heights and times of collection), can tolerate incremental updates to the main product within a reasonable compute load, and can achieve results within a reasonable tolerance without requiring manual intervention. This presentation focuses on the intended approach to compilation and the expected outcomes, based on a test-case.
