An introduction to Paleointensity.org - Annemarieke Béguin - 2021 MagIC Workshop (1/20/21)

"An introduction to Paleointensity.org - interpretation of paleointensity data & working with MagIC files" by Annemarieke Béguin, XX Lightning poster talk presented at the virtual 2021 MagIC Workshop (https://earthref.org/events/MAGIC/2021/) - Rock and Paleomagnetism through Time and Space. Jan 19th-21st, 2021. Abstract: Annemarieke Béguin(1), Greig Paterson(2), Andy Biggin(2), Lennart de Groot(3) (1) Institute of Geoscience and Petroleum, Norwegian University of Science and Technology, Norway (2) Geomagnetism Laboratory, Oliver Lodge Labs, School of Environmental Sciences, University of Liverpool, United Kingdom (3) Paleomagnetic Laboratory Fort Hoofddijk, Department of Earth Sciences, Utrecht University, Netherlands Paleointensity.org is an online, open source, application to analyze paleointensity data. It aims to ease and standardize the interpretation of the most commonly used paleointensity techniques. Our application currently supports a variety of input file formats for four different paleointensity methods: thermal Thellier (all variations), microwave Thellier, pseudo‐Thellier, and the multispecimen protocol. A full description of the application, the supported data formats, and instructions for use can be found in Béguin et al. (2020). The data for the individual paleointensity methods are visualized by the applicable graphs and parameters. These are updated dynamically while interpreting the data. The data can be interpreted on specimen level with easy-to-use key-board controls. An automated interpretation option is available for the interpretation of Thellier-type data. Although the application runs in a web browser, all data is stored locally and is not sent over the internet for its interpretation. It is possible to export the local storage containing all data, saved interpretations, and settings. This exported file can be shared with colleagues, used for teaching purposes, or appended to a publication. The local storage file can later be imported to the application to visualize all data and interpretations. Furthermore, the data and interpretations can be exported to csv files and MagIC files. Paleointensity.org also supports the import of MagIC measurements files or MagIC contributions. Paleointensity.org is a major step forward in standardizing data interpretation for multiple methods, and with the possibility to easily export to the MagIC database we enhance an open paleomagnetic community in line with the findable, accessible, interoperable, and reusable data principles.
