This document describes the SCAR Retrospective Analysis of Antarctic Tracking Data (RAATD) project. The project involves analyzing over 4060 animal tracking records from 17 Antarctic species, totaling nearly 3 million location points. The goal is to identify Areas of Ecological Significance in the Southern Ocean that are important for multiple predator species and have high biodiversity of lower trophic levels. Habitat utilization models are being developed for each species to predict habitat use globally based on environmental conditions. Preliminary results from a habitat model for Southern elephant seals are shown, identifying regions of high and low predicted habitat suitability. The project aims to improve understanding of Antarctic ecosystem processes and inform spatial management decisions.
