Summary
This article presents a novel method using high-resolution Umbra synthetic aperture radar (SAR) imagery (25–30 cm resolution) to track the wintertime phenology and behavior of emperor penguins in Antarctica. The research addresses a significant gap in biodiversity distribution data, as marine mammals and seabirds are severely underrepresented in global biodiversity databases. By combining satellite radar imagery with ground validation, the study enables monitoring of emperor penguin colonies during the Antarctic winter—a period previously difficult to observe due to extreme conditions and darkness. The method offers a new approach for tracking these remote animals during critical life stages.
