After the violent attack by the Libyan Coast Guard in August which forced a four-month suspension of its operations, the Ocean Viking is about to return to sea.

How many #migrants die en route to the #CanaryIslands? In an article, IMIS- & #SFB1604 member @mauricestierl.bsky.social and @msdionis.bsky.social analyze data collection practices and contradictory numbers. They demonstrate that the data has practical consequences and produces multiple realities.
