- •
Sensitivity analyses to assess the ecosystem’s responses of Hiroshima Bay were conducted.
- •
Different N and P load levels were applied for the sensitivity analyses.
- •
P had a significantly greater impact on the primary production than N.
- •
25% increase of P load increased the primary production but led to N-limitation.
- •
25% simultaneous increase of P and N could bring the ecosystem back to eutrophic state.
