His primary focus is mapping global fisheries and their interactions with marine ecosystems. Professor Watson collaborates in global studies of marine biodiversity, economics of fishing and the impacts of fishing on birds and mammals. His goal is the development of better methods to assess the health of exploited marine systems, the impacts of climate change and the social consequences of mismanagement in our oceans. He is also concerned with food security and how our needs impact on global oceans. Currently his research includes global certification of seafoods, and the potential benefits and impacts of geo-engineering in our oceans. Professor Watson has over 35 years experience with international fisheries.
