Led by researchers at the Marine Biological Association and the COVID-19 Bio-Logging Initiative, a study has unveiled the intricate changes in global shipping and fishing activity during the COVID-19 pandemic in 2020. Using satellite and nightlight data, the research provides unparalleled detail on the impact of restrictions and lockdowns on human mobility at sea.
Key Findings
- Small Global Changes: Exclusive Economic Zones saw a 1.35% decrease in shipping activity, while high-seas shipping activity increased by 0.28% globally.
- Context-Dependent Responses: Significant variations at smaller scales based on area, vessel type, and period examined. For instance, passenger vessels were notably less active in 97% of Mediterranean Sea coastal states.
- Diverse Drivers: Not all changes were solely due to the pandemic; geopolitical tensions, mobile fishing fleets, and ongoing trends in marine sectors also played roles.
Implications
The study emphasizes the need for a nuanced analysis of maritime traffic, stressing the importance of considering various factors influencing activity. Researchers advocate for continued monitoring using multiple data sources to understand the long-term impacts of the pandemic on maritime industries and the marine environment.
