Adi Kellermann passed away in February 2025, leaving behind a lifetime of scientific excellence and unwavering commitment to marine conservation. His legacy at ICES, where he served as Head of the Science Programme from 2004 to 2016, is one of transformation, innovation, and a commitment to bridging the gap between science and policy.
Adi's journey in marine science spanned decades and continents. Beginning with Antarctic research at the Alfred Wegener Institute, he later expanded his expertise in Hawaii before taking on leadership roles in Germany's National Park Office.
Adi's leadership skills led him to ICES, where he served as the Head of the Science Programme from 2004 to 2016. In this role, he oversaw a diverse portfolio encompassing climate change, biodiversity, ecosystem modeling, and conservation. His tenure was marked by fostering interdisciplinary collaboration and expanding ICES scientific reach. He saw the organization evolve into a more integrated and outward-looking institution, engaging with global partners, expanding into Arctic and aquaculture research, and fostering interdisciplinary collaboration.
A passionate advocate for open dialogue and scientific progress, Adi was never afraid to challenge conventions. He was instrumental in strengthening ICES role in international projects and cooperation, helping the organization establish itself as a key player in global marine science. His enthusiasm extended to the Annual Science Conference, which he saw as a vital forum for exchanging ideas and building partnerships. As Head of Science at ICES, Adi was a compassionate and respected team leader. His positive attitude to life rubbed off on his team and colleagues, and his door was always open for an exchange on matters big or small.
Adi was also instrumental in developing collaboration between ICES and PICES, the North Pacific Marine Science Organization, bridging the scientific communities of the two organizations through joint research initiatives.
Even after leaving ICES, Adi remained deeply engaged in marine science and conservation, taking on consultancy roles, leading local scientific societies, and continuing to inspire future generations of researchers. His dedication, intellect, and warm spirit will be sorely missed but never forgotten.
Over the years, Adi maintained close ties with many of his former colleagues, always reaching out with a kind word, thoughtful birthday greetings, and updates on his life, his family, and his cherished grandchildren. His genuine care for those around him extended beyond work, as he made sure to stay in touch and remain a part of their lives.
Beyond his formal roles, Adi was actively involved in voluntary commitments, including chairing the local section of the Schleswig-Holstein University Society and the local museum club in his hometown of Friedrichstadt. His dedication to marine science and conservation left an indelible mark on the scientific community and environmental stewardship.
We extend our heartfelt condolences to his family, friends, and colleagues. Adi's impact on ICES and the broader marine science community will endure for years to come.
