This article provides valuable information about the marine research stations, their history, infrastructure, and research capacities, but lacks a dedicated research question, methodology, results, and discussion as one might expect in a traditional scientific paper. Thus, the rating is capped at 3 as it predominantly serves as an informative overview of the facilities.
