A study, aimed to track tagged seabirds’ behaviour and movements along the coast, revealed that, at night, these seabirds spent a lot of their time idle on the sea surface.

Using seabirds to tell us about the tide could be especially useful for the marine renewable energy industry. Generating tidal energy requires detailed knowledge of current speeds. Scientists and engineers traditionally measure tides by using radar or deploying anchors and buoys with scientific instruments. However, these scouting methods are challenging and expensive. If tagged seabirds could provide tidal data over a large area, they could help identify sites that would be good sources of tidal energy…
