We propose the need of combining Earth system sciences with data sciences and give our perspective on how this could be accomplished within a subfield of marine sciences. Marine data hold abundant information and insights data science techniques can reveal. There is high demand and potential to combine skills and knowledge from marine and data sciences by establishing Marine Data Science as a new research discipline. Marine Data Science is an interface science that applies data science tools to extract information, knowledge and insights from the exponentially increasing body of marine data. Marine Data Scientists need to be trained data scientists with a broad basic understanding of marine sciences and expertise in knowledge transfer. Marine Data Science doctoral researchers need targeted training for these specific skills, a crucial component of which is co-supervision from both parental sciences. They also might face challenges of scientific recognition and lack of an established academic career path. In this paper we, marine and data scientists at different stages of their academic career, present perspectives to define Marine Data Science as a distinct discipline. We draw on experiences of a Doctoral Research School, MarDATA, dedicated to training a cohort of early career Marine Data Scientists. We characterize methods of Marine Data Science as a toolbox including skills from their two parental sciences. All of these aim to analyze and interpret marine data, which build the foundation of Marine Data Science.
