RAATD

Retrospective analysis of vertebrates’ tracking data in Antarctica to identify ecologically significant areas

RAATD

The overall objective of the project RAATD is to assess habitat use by several predator species at the top of Southern Ocean food chains from existing spatial monitoring data sets of these animals. This approach identify ecologically important areas for predators, i.e. ocean regions that serve as preferred sites for food exploration for several predator species simultaneously, and therefore that have high biodiversity.

 

The project:

  • provided a better understanding of the fundamental ecosystem processes in the Southern Ocean,
  • facilitated projections of future distributions of predators under different climatic regimes and,
  • identified areas of ecological significance (with high biodiversity and species abundance) and provides this information to land and resource managers, such as the Convention on the Conservation of Antarctic Marine Living Resources,
  • highlighted gaps in data coverage for regions or seasons that are biologically important but under-sampled, due in particular to a low human presence in these areas of the Southern Ocean.

 

RAATD expert group has gathered all available monitoring data collected by research groups that have worked in Antarctica since the 1990s. They have set up a  repository of these data that is accessible to the public. The repository, contains the data of more than 40 contributors working in 12 national Antarctic programmes, on 15 predator species, with 3,447 individuals and more than 2.4 million entries.
