# British Antarctic Survey Launches Largest Ever Penguin Census The 2026/27 research season deploys advanced aerial technology to monitor Antarctic wildlife populations. - **Source:** [MercoPress](https://en.mercopress.com) - **Published:** 2026-11-12 - **Topic:** [science](https://brifing.si/c/science) - **Original article:** - **On Brifing:** https://brifing.si/s/9669fc43-b6b2-4813-916c-1dc5a9a95e2c ## Season Commencement and Logistics The British Antarctic Survey officially launched its 2026/27 research season in late October. Operations are supported by the RRS Sir David Attenborough icebreaker, which utilizes hydrotreated vegetable oil to minimize carbon emissions. Personnel and equipment are currently deployed across five distinct British research stations to facilitate comprehensive scientific data collection efforts. ## Massive Penguin Population Census Researchers are conducting the largest penguin census in Antarctic history using specialized aerial camera systems. The project targets approximately 200 colonies of Adélie, chinstrap, and gentoo penguins across the Antarctic Peninsula and surrounding island groups. This initiative builds upon successful trials conducted during the previous season to ensure high-accuracy population tracking. ## Ecological Impact and Conservation Data gathered from the penguin census will be submitted to the Commission for the Conservation of Antarctic Marine Living Resources. Scientists aim to evaluate population fluctuations and analyze the potential impacts of commercial krill fishing on these species. This long-term monitoring is essential for developing effective regional conservation and management strategies. ## Innovative Whale Monitoring Systems The season introduces the first drone-based monitoring system designed to assess the body condition and demography of humpback whales. These populations have shown signs of recovery following the cessation of commercial whaling activities. Drones provide a non-invasive method for researchers to gather vital health data on these recovering marine mammal groups. ## Investigating West Antarctic Ice Loss A multinational team is utilizing the autonomous submarine Autosub Long Range to study warm water flow into the Amundsen Sea. This phenomenon is identified as a primary driver of ice loss in West Antarctica. Understanding these thermal variations is critical for predicting future stability of the regional ice sheets and global sea levels. ## Ice Shelf Protection Research Specialized teams are investigating the compacted snow layer that serves as a protective barrier for ice shelves against melting. In a collaborative effort with NASA and the California Institute of Technology, researchers will deploy advanced instrumentation beneath the Filchner-Ronne Ice Shelf to measure structural changes and thermal interactions within the ice. ## Four Decades of Fish Data The groundfish survey at King Edward Point station in South Georgia marks its 40th anniversary this season. Initiated in 1987, this record represents one of the longest continuous datasets in the Southern Ocean. It remains a fundamental tool for analyzing how ocean warming trends influence fish stocks and the broader marine ecosystem. ## International Scientific Collaboration BAS Director Professor Dame Jane Francis emphasized that international cooperation is central to the success of Antarctic research. The current season features active participation from researchers representing Chile, the Netherlands, the United States, and Australia. These partnerships ensure the continuity of long-term monitoring programs necessary for understanding complex global environmental shifts. ## Sources covering this story - https://en.mercopress.com/2026/11/12/british-antarctic-survey-begins-a-season-featuring-the-largest-ever-penguin-census?utm_source=feed&utm_medium=rss&utm_content=main&utm_campaign=rss — --- _Summary written by Brifing from the original reporting.
