The Ocean tracking network: a data perspective

Joanna Mills Flemming, Dalhousie University


The Ocean Tracking Network (OTN) is an international research and technology development consortium, led by Dalhousie University.  The primary purpose of the network is to support the most comprehensive and revolutionary examination of marine life and ocean conditions in history with the emphasis on understanding how they are changing as the earth warms. Data are being collected on all five of the world’s oceans and all seven continents.  Remarkably, most of these data will be collected from acoustic tags surgically implanted or attached externally on a wide range of aquatic species including salmon, tuna, whales, sharks, penguins, crabs and seals.  State-of-the-art statistical models for the analysis of OTN acoustic tagging data will be discussed with particular emphasis on data being obtained via bioprobe technology. Bioprobes are large vertebrates (seals, for example) that are instrumented with acoustic tags that record when and where they encounter other acoustic-tagged species. In this talk I will review the statistical methodologies and visualization tools under development to assess the conditions under which bioprobes and acoustic-tagged species are likely to encounter one another, with a view to determinant the long-term feasibility and efficiency of utilizing bioprobes within the OTN.
