What seabirds can tell us about the tide

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.

Watching Out for Whales

The blue whale—the largest animal on Earth—measures on average 27 meters (89 feet) long. But its impressive size does not mean the species is safe in the sea. A national database for marine mammal health reported that collisions with ships killed 10 of the 12 blue whales found dead along the California coast between 2007-2017.
