As part of the ongoing discussion on the blue turn and divergent research perspectives on ocean governance, international relations and maritime security, we held another iteration of the blue ideaslab on the 28the of May. The blue ideaslab provides an open format to discuss research and project ideas as well as work in progress. While previous versions were held physically at the University of Copenhagen, this iteration was online, which also enabled broader international participation. Three sets of ideas were discussed under the title “Crimes and Order at Sea”. Jan Stockbruegger from Brown University introduced his research on the history of maritime order, Edyta Rozko, Senior Researcher at the Chr. Michelsen Institute in Bergen, Norway presented insights from her ongoing research project on fisheries, and Tim Edmunds and myself presented our recent paper on the intersections between different blue crimes.
