Abstract The significance of a halocline for nutrient cycles in a shallow coastal lagoon, Lake Nakanoumi, was investigated. The study was made possible when the northern part of the lagoon was enclosed by polder dikes prior to land reclamation for agricultural purposes. The disappearance of the halocline allowed vertical mixing to extend to the whole depth and vertical gradients in water properties then decreased remarkably. Despite the disappearance of the halocline, dissolved oxygen content of bottom waters decreased considerably during summer months. Summer peaks in inorganic nitrogen and phosphate were still observed after disappearance of the halocline.
