Mapping blue whale movements involves using satellite tracking and GIS technology to monitor their migration patterns across vast oceans. Researchers tag whales with GPS trackers to collect location data over time. This data was analyzed in ArcGIS Pro to visualize their routes. Mapping these movements helps scientists understand habitat use, assess threats like shipping lanes or climate change, and guide conservation efforts. By visualizing their epic journeys, we can work toward protecting the world’s largest mammal and its marine environment.
