The research vessel Dr. Fridtjof Nansen cancelled a planned survey of Sri Lankan waters in 2025 after government approval was delayed. Operated by Norway’s Institute of Marine Research and commissioned by the UN Food and Agriculture Organization under the EAF‑Nansen Programme, the ship provides oceanographic surveys used to manage marine resources sustainably.
Sri Lanka had imposed a one‑year moratorium on foreign research vessels in December 2023, which was lifted in December 2024. Authorities did not finalise standard operating procedures in time, so a special presidential approval arrived too late and FAO reassigned the mission to Madagascar. The Nansen had been due in Sri Lankan waters from 15 July to 20 August 2025.
Past Nansen missions collected data on temperature, salinity, oxygen and chlorophyll and supported studies of plankton, deep‑sea life and seafloor habitats. Scientists say the cancelled mission will slow work on fish abundance, seasonal patterns and changing ocean conditions.
