The Acoustic Tracking Array Platform (ATAP), hosted by the South African Institute for Aquatic Biodiversity and an official partner of the Canadian-based global Ocean Tracking Network (OTN), provides a backbone of acoustic telemetry hardware to facilitate the large-scale, long-term monitoring of acoustically tagged marine animals. Tagged animals are monitored by a network of more than 250 moored acoustic receivers spanning approximately 2200 km of the South African coastline, from False Bay in the Western Cape to Ponta do Ouro at the South Africa/Mozambique border.
