Tuna, one of the most valuable fish species in the ocean, necessitates a contemporary industrial synergy that forms a collective planetary urbanism transcending space, nations, and languages, particularly in the vast Pacific fishing grounds, to maximize its economic extraction. The ocean, conceptualized as a fluid urbanized space, operates independently of established urban nodes and other maritime infrastructure between countries. As a region optimized for maximal extraction of resources, its primary importance lies in the manipulation of fluid resources and the boundaries of rights. Following the Tuna, the research aims to reveal various scales and steps in transnational extraction operations. The project was developed within the context of SMArchS Urbanism at MIT and was advised by Rania Ghosn.
