- •
A comprehensive study on sediment P in the N Baltic Sea archipelagos was conducted.
- •
High levels of phosphorus were found across the study area.
- •
Fractionation of potentially mobile P suggested a high potential for internal loading.
- •
Internal P loading can occur under particular conditions, especially hypoxia.
- •
Internal loading of phosphorus stimulates productivity of N2-fixing cyanobacteria.
