Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 10, October 2025.Abstract Globally, nutrient enriched water bodies are major contributors to the aquatic greenhouse gases (GHG) efflux to atmosphere. However, few efforts have focused on assessing the contribution from coastal transitional ecosystems in Africa. To improve our knowledge of these systems, we investigated emissions in Lake Nokoué, a coastal lagoon in ...
