Rationale: Seabirds constitute important components of the Barents Sea ecosystem. They form an important link between the marine and terrestrial ecosystems by bringing nutrients from sea to land. As predators covering many niches, seabirds can be used as indicators of health of the marine ecosystem at large.
Type of indicator: E, state of the ecosystem.
Priority of indicator: e, essential.
