Greek oceanographers Dionysia Rigatou and Eleni Kytiou accomplished a significant milestone by performing the first scientific dive from the Bulgarian base St. Clement of Ohrid, located on Livingston Island in Antarctica. This dive marks a historic event as no scientist conducting research on Bulgarian Antarctic missions has previously dived in these waters. Their participation in the 34th Bulgarian Antarctic Expedition is crucial for advancing scientific understanding in one of the most remote and extreme environments on the planet.

During this expedition, Rigatou and Kytiou aim to study the marine food web in Antarctic waters. Their research necessitates the collection of samples from various locations and depths, which they achieved through their underwater exploration. The dive was backed by a logistical support team and the local doctor, Dr. Atanas Peltekov, ensuring everything proceeded safely and effectively. The scientists' work is not only a breakthrough for Bulgarian Antarctic research but also adds valuable data to global marine science efforts.

The expedition began with the departure of the Bulgarian research vessel Saints Cyril and Methodius (RSV 421) from Varna on November 7, 2025, suggesting a long-term commitment to exploring and understanding the unique ecosystems present in Antarctica. As these oceanographers delve deeper into unexplored territories, their insights could significantly contribute to understanding the impact of climate change on marine life, thereby emphasizing the importance of such international collaborative scientific efforts in conservation and environmental monitoring.
