The retrospective analysis of Antarctic tracking data project

Area of Science:

• Marine Ecology
• Antarctic Biodiversity
• Predator-Prey Dynamics

Background:

• The Retrospective Analysis of Antarctic Tracking Data (RAATD) is a collaborative project.
• It is led by expert groups on Birds and Marine Mammals and Antarctic Biodiversity Informatics.
• The project is endorsed by the Commission for the Conservation of Antarctic Marine Living Resources.

Purpose of the Study:

• To consolidate tracking data for Antarctic meso- and top-predators.
• To identify Areas of Ecological Significance within the Southern Ocean.
• To support ecosystem process understanding, climate change modeling, and management decisions.

Main Methods:

• Compiled historical tracking data from research groups working in Antarctica since the 1990s.
• Included data from over 70 contributors across 12 national Antarctic programs.
• Integrated data from 17 predator species, 4060 individual animals, and over 2.9 million locations.

Main Results:

• A comprehensive archive of Antarctic predator tracking data has been created.
• The data facilitates a greater understanding of Southern Ocean ecosystem processes.
• The datasets are publicly accessible via biodiversity.aq and the Ocean Biogeographic Information System.

Conclusions:

• The RAATD project provides a valuable resource for Antarctic marine ecosystem research.
• The compiled data aids in predicting predator distributions under future climate scenarios.
• This initiative supports informed decision-making for Antarctic marine resource management.
