This study adopts a novel mix of scientometrics, theme-based, citation-based systematic review and interpretative aggregation approach (STCSR-IA) with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) method. It presents a macro-level scientometric analysis of tourism research in coastal, marine and maritime (blue tourism) environments by using 986 research articles published in 130 Scopus-indexed journals from 2000 to 2019. The thematic evolution of research in five time periods of four years each (2000–2003, 2004–2007, 2008–2011, 2012–2015, 2016–2019) was analysed using the authors’ keywords and classified as (a) preliminary (b) transversal stage I (c) transversal stage II and (d) growth stage. The massive evolution of research areas in the growth stage and their themes along with the growing nexus of conceptual relationship within blue tourism is systematically reviewed and presented as a thematic research framework.
