It is with heavy hearts and profound gratitude that the GEF International Waters community bids farewell to Dr. Kenneth Sherman, who passed away peacefully last week. A scientist, adventurer, and visionary, Dr. Sherman leaves behind a "fully lived life" that fundamentally changed the way humanity protects its oceans.
Generally recognized as the father of the Large Marine Ecosystem (LME) approach, Ken’s extraordinary journey began on the piers of Boston with his father. While he nearly pursued a career in law, a pivotal mentor steered him toward marine science - a choice that would eventually impact 110 countries and all 66 of the world's LMEs.

A Legacy of Science and Connection
Dr. Sherman understood a truth that has become the bedrock of the GEF IW portfolio: you cannot achieve effective management without linking social and natural sciences. Over a career spanning more than six decades, he authored over 200 publications and 20 book volumes. As a founding director at NOAA, a professor, and a convener of global meetings, he worked tirelessly to ensure that science-based assessments were standardized and applied to protect living marine resources globally.
Even in his later years, Ken never abandoned the "topic of his heart." He remained a passionate advocate for the LME framework, ensuring that the next generation of ocean lovers had the tools to manage the seas sustainably.
Continuing the Work
Ken’s family notes that he led a life of deep passion and curiosity. In lieu of flowers, and in true character for a man dedicated to knowledge-sharing, his family suggests honoring his legacy by engaging with his work:
Attend his Coursera course
Large Marine Ecosystems: Mechanisms for Sustainable Development Listen to his story
NOAA Voices: Oral History of Kenneth Sherman
Ken Sherman built the framework that allows the rest of us to save it. He will be deeply missed, but his legacy is as vast and enduring as the ecosystems he spent his life protecting.
