2023 MagIC Workshop

MagIC hosted its 2023 workshop from Feb 28th to March 2nd, 2023 in La Jolla, California at the Scripps Institution of Oceanography, UCSD. The workshop, "Magnetism and Earth History: Field Evolution, Environmental Change and Paleogeography", consisted of two days of science talks in four sessions and a day of MagIC-related group working sessions. Please visit the workshop website for the full schedule and other workshop details.

2020 MagIC Workshop Tutorial Videos

In lieu of the postponed 2020 MagIC Workshop, Magic hosted a series of tutorials over three days covering some of the material which was to be presented in the hands-on part of the workshop. The first was on the MagIC data model and the uploading of data to the MagIC database, the second was on the PmagPy Demag GUI data import, analysis, and MagIC file export software, the third was on using PmagPy and Jupyter notebooks. These tutorial videos and others can be found on the 2020 MagIC Workshop Tutorial playlist on the MagIC YouTube Channel.

Mag-NetZ

MagNetZ (Magnetic NetworkZ) is a biweekly online seminar organized by Greig Paterson and Anita Di Chiara. The seminars cover topics in the geomagnetism, paleomagnetism, rock magnetism, archeomagnetism, and environmental magnetism (all things magnetic). Visit the website for info on all the speakers, their abstracts, as well as links to the YouTube videos, ERDA entries, citable DOIs.

2021 MagIC Workshop

MagIC hosted its 2021 workshop on January 19th-21st, 2021 online via Zoom and Slack with 194 participants. Titled "2021 MagIC Workshop: Rock and Paleomagnetism through Time and Space", it consisted of three days of science talks in four sessions. Visit the workshop website for the full schedule and other workshop details. The workshop talks and poster lightning talks are up on our YouTube channel. The posters can be found on MagIC's Slack channel. Email Nick Jarboe (njarboe@ucsd.edu) to request an invite to the channel.

MagIC at AGU

MagIC presented an eLightning talk on Tuesday morning at 10:20 AM (IN22B-01 - Thorough Annotation of Magnetics Information Consortium (MagIC) Contributions with Schema.org Structured Metadata) and a poster on Thursday afternoon (GP43A-0788 - Magnetics Information Consortium (MagIC) Database Interoperability Improvements: ORCID, EarthCube, Google, and PmagPy) at the 2019 AGU Fall Meeting.

Project 419 / GeoCODES

MagIC is working with EarthCube GeoCODES to publish JSON-LD contribution metadata. MagIC is providing a rich selection of HTML5 microdata schema.org parameters for its versioned datasets and associated references. These embedded metadata are also suitable for crawling by the European Plate Observing System and Google Search with Structured Data.
