The expansion of research data availability and production has highlighted the need for proper training in data stewardship. Recent years have seen both incentivized and mandated research data management plans enacted by institutions and funding agencies as a way of supporting more open and integrated data-intensive research. Despite the advancement of data management as a practice and profession, those charged with maintaining and curating research data remain understudied. By investigating "what" and "how" data management is realized and "who" is involved, a discussion on the current educational needs, the trajectory of professions, and an assessment of potential educational needs of those entering the workforce can progress. A job analysis survey was developed to validate the tasks identified from two prior interview studies of Earth Science data managers. This survey was distributed to the Federation of Earth Science Information Partners membership and responses validate prior job analyses work as well as provide other educational consideration related to tools and necessary skills to conduct frequent job tasks. The most frequent activities and necessary knowledge, skills, and abilities of current data managers will inform future avenues of inquiry, provide context for current research, and direct research data management education.
