Summary:

- The article discusses a study that used surveys to assess the full-scale impact of a massive seabird die-off event in the Northeast Pacific Ocean in 2022-2023.
- The study found that the die-off event, which was likely caused by a combination of factors including climate change, resulted in the deaths of millions of seabirds, including common murres, tufted puffins, and other species.
- The researchers emphasize the need for continued monitoring and research to better understand the long-term impacts of such events on marine ecosystems and the importance of addressing the underlying causes, such as climate change, to prevent similar catastrophic losses in the future.
