Building on processual border theory (bordering–debordering–rebordering) and recent work on oceanic bordering and governance, the paper develops a mechanism-based model explaining how rebordering is produced through coercive-security practices, regulatory–juridical gating, risk–market pricing, information–surveillance regimes, and material–infrastructural/environmental constraints, while treating irregular migration, piracy, and other non-state violence as recurrent activation drivers that mobilise these mechanisms. The model is operationalised through four diagnostic case studies: Hormuz, Gibraltar, the Bab al-Mandeb–Suez corridor, and the Danish Straits/Kiel Canal, analysed via a common matrix. The paper contributes a transferable typology and a flowchart of “rebordering activation logic” that clarifies why maritime borders are increasingly experienced as selectively permeable infrastructures of power – open to some flows, filtered or closed to others – under conditions of geopolitical volatility, securitisation, and environmental disruption.}, title={Open seas rebordered: A mechanism taxonomy of rebordering in strategic passages}, type={Tekst}, URL={http://rcin.org.pl/Content/263257/WA51_300336_r2026-t99-z3_G-Polonica-Ceric.pdf}, keywords={granice morskie, zmiana granic, punkty newralgiczne, cieśniny, geopolityka, selektywna przepuszczalność, bezpieczeństwo morskie, nielegalna migracja, przemoc ze strony podmiotów niepaństwowych, świadomość sytuacji w obszarze morskim, wycena ryzyka}, }
