Talk of a ‘migration crisis’ calls forth three related spatial renderings of the Mediterranean Sea. Their social production involves a particular politics of visualization. First, the Mediterranean is but one leg of a longer migration corridor, yet as such substantiates a geo-racial border zone. Second, scenes of rescue at sea have functioned as border spectacles, naturalizing migration politics. Third, expanding surveillance infrastructure has undermined a firewall between border patrolling and search-and-rescue, thereby helping to create and sustain an ethical landscape of response-ability to routinized emergency. Visualizing and disseminating this landscape has, for the moment, created a political space between wanted and unwanted mobilities.
