This year, a review of a special kind awaits you. Look back on an eventful year in IFZO-Baltic-Sea-Region-Research by means of our Twitter posts. With more than 120 posts with an average of 3,000 to 7,000 views of our tweets per month, we can only present a selection here. However, it provides a detailed look at our activities, results, discussions, and the large framework that accompanied our work this year. And yes, there were more activities and results, but they may not have made it into the post series. As an IFZO member, feel inspired to contribute to our social media activities and contribute a post now and then about your research, discussions, and events! Merry Christmas and a Happy New Year!
