North Atlantic winter cyclones starve seabirds
Each winter the North Atlantic Ocean is the stage for numerous cyclones, the most severe ones leading to seabird mass-mortality events called ‘winter wrecks’ (1–3). During those, thousands of emaciated seabird carcasses are washed ashore along European and North American coasts. Winter cyclones can...
