UNEP Webinar 3

Science of sargassum | West Africa perspective

22 September 2020 | Online

The unprecedented recent invasion of Sargassum seaweed, free-floating brown seaweed that blossoms naturally in the warm waters of the Sargasso Sea, on coastal shores in West Africa and Caribbean shores is being attributed to factors that include warming of the ocean due to global climate change, discharge of nutrients (nitrogen and phosphorus) from agricultural run-off and wastewater originating from point sources and from major river basins such as the Congo and Amazon Rivers, and the deposition of iron and nutrient-rich Saharan dust on the ocean.

This third webinar will focus on the West Africa region perspective on Sargassum.
