The Royal Canadian Navy’s HMCS Margaret Brooke returned to Halifax on May 9, 2025, after a four-month deployment to Antarctica, covering nearly 25,000 nautical miles. The mission, which included 83 crew members and 15 scientists, aimed to study the effects of climate change on glaciers while fostering relationships with Latin American countries. The ship encountered diverse wildlife and navigated challenging conditions, providing significant scientific data that will be analyzed to understand glacier retreat and climate change trends.
