Dimitris Poursanidis

Dimitris Poursanidis, Ph.D., is a marine scientist and Earth observation analyst focused on understanding our seascapes. With expertise in marine ecology and biodiversity, he has dedicated his career to studying marine ecosystems and the impacts of human activity. Driven by a passion for conservation, Dimitris investigates the relationships between marine life and their environment, promoting biodiversity protection and sustainable practices. A key area of his work is seagrass ecosystems, where he uses advanced technologies like satellites and drones. Through remote sensing, he monitors the health and extent of seagrass meadows, offering valuable insights into their dynamics and resilience under environmental stress. Beyond monitoring, Dimitris contributes to seagrass restoration, applying his knowledge in marine ecology to design effective strategies. Working with interdisciplinary teams, he merges science and field practice to boost seagrass recovery amid growing anthropogenic pressures. His holistic approach to conservation seeks to inspire action and raise awareness of seagrasses’ vital role in coastal biodiversity and human well-being. Dimitris exemplifies a deep commitment to ocean protection and a sustainable future. He is a member of the UNESCO GOOS Biodiversity and Ecosystems Panel, co-leads the Seagrass EOV, and is part of the UN/CMS 2030 Seagrass Breakthrough. He also belongs to the Mediterranean Posidonia Network and co-authored the “Guidelines for the Restoration of Posidonia oceanica” (2024). He was lead author of UNEP/GRID’s “Out of the Blue: The Value of Seagrasses” (2020) and has published 60+ peer-reviewed articles on seagrass mapping, monitoring, and biodiversity. He is also an underwater multimedia creator, producing content to raise local awareness.
