Communication is a key aspect of a scientist’s work. Part of our mandate is to communicate findings not only to the research community, through peer-reviewed articles, but also to the wider public. Raising awareness of how science serves the public is becoming increasingly important. There are few incentives, and generally negligible financial support, for scientists to communicate with the general public. @oceanseaicenpi is an initiative led by a small team of researchers who are exploring the use of social media for science outreach. Over the past four years, @oceanseaicenpi has built a global audience of more than 7,000 followers, successfully sharing knowledge and findings in polar oceanography and related disciplines. By presenting the benefits and sharing advice on how to create and run social media accounts for science outreach, we hope to inspire research groups, individual researchers, and institutions to further engage in science communication using social media.
