The Multidisciplinary drifting Observatory for the Study of Arctic Climate () was an international, interdisciplinary Arctic scientific expedition that drifted across the central Arctic from autumn 2019 to autumn 2020. The 2nd International Science Conference will be held 13-17 February 2023 at the University of Colorado in Boulder, Colorado, USA. Conference objectives are to foster cross-cutting scientific analysis, address issues of spatiotemporal scaling of information, and promote advancement of modeling and predictive capabilities. The weeklong conference will offer a mix of plenary sessions with visionary keynote presentations, focused breakout sessions on a variety of thematic topics, poster sessions, flex-time for ad hoc meetings, a planetarium film viewing, and much more. The conference will build upon the 1st International Science Conference from April 2022. Since observational data are expected to be publicly available by the start of 2023, this conference is an opportunity to expand the science community through the use of these data. Conference participation is open to all, with the expectation that all contributions are focused on -related research.
