The paper addresses sustainability, heritage, management, and communication from UNESCO’s Marine World Heritage (MWH) perspective, analyzing its digital narrative footprint through social media. It aims to understand how MWH is conceptualized, managed, and communicated and whether it is framed with sustainability and biocultural values facilitating interactivity, engagement, and multimodal knowledge. Hence, a content analysis of the Instagram accounts of the MWH of Outstanding Universal Value (OUV) sites and protected areas has been conducted. The study included evidence from their Instagram profile, posts, features, and reactions. The findings indicated the dearth of a management and communication strategy being shared among and across UNESCO’s MWH of OUV sites and protected areas, capturing the “lifeworld” and the “voice” of the marine heritage as unified. They also revealed that nature and human, and biological and socio-ecological ecosystems of MWH of OUV sites and protected areas are not interlinked in marine heritage management and communication featuring the whole and the entirety of the marine heritage site ecosystem. The lack of this expansion of meaning and engagement does not facilitate the shift of the route in the marine-scape, from discovery and being listed as World Heritage to human-nature interaction, diversity, dynamicity, and ocean literacy. The study contributes to setting the ground rules for strengthening marine heritage management and communication in light of the United Nations Sustainable Development Goals (SDGs) and the Ocean Literacy Decade (2021–2030).
