This is an acoustic telemetry dataset published by the Flanders Marine Institute (VLIZ). It contains animal (arthropod) tracking data collected by the Permanent Belgian Acoustic Receiver Network (https://lifewatch.be/en/fish-acoustic-receiver-network) for the project/study 2015_homarus, using VEMCO tags (V13) and receivers (VR2AR). Two individuals of European lobster (Homarus gammarus) were captured, tagged and released in April 2014 in the Belwind wind farm in the Belgian Part of the North Sea, to study the potential to tag and detect lobsters using an existing receiver setup. Tags were attached externally, using a cap which was attached to the base of the pincher claw with a tie-wrap. ... : This dataset was collected using infrastructure provided by VLIZ and INBO funded by the Research Foundation - Flanders (FWO) as part of the Belgian contribution to LifeWatch. Data were exported from the European Tracking Network data portal (http://www.lifewatch.be/etn) developed by VLIZ using the ETN R package (https://inbo.github.io/etn/) developed by INBO. Field definitions can be found at https://inbo.github.io/etn/articles/etn_fields.html. ...
