COVID-19大流行对人类流动性造成了前所未有的全球影响。在海洋中，人们认为，由于对人类活动的严格限制和消费的变化，船舶活动受到了影响。在这里，我们量化并绘制了2020年上半年全球海上交通的变化。70.2%的专属经济区减少，但变化在空间和时间上与限制措施一致。全球下降在4月份达到顶峰，交通占用率下降1.4%，54.8%的抽样单位出现下降。客船的跌幅较显著及持续较长时间。在西地中海进行的一项区域评估对恢复速度和长期变化有了进一步的了解。我们的方法为大规模监测COVID-19对船舶交通的进展和潜在影响提供了指导，这些影响可能随后影响蓝色经济和海洋健康。COVID-19的应对措施导致人类社会的运作发生了前所未有的变化，从旅行限制到消费变化。在这里，作者使用高分辨率卫星数据来跟踪大流行期间全球海上交通的减少，以及最近恢复到封锁前水平的迹象。
The COVID-19 pandemic has resulted in unparalleled global impacts on human mobility. In the ocean, ship-based activities are thought to have been impacted due to severe restrictions on human movements and changes in consumption. Here, we quantify and map global change in marine traffic during the first half of 2020. There were decreases in 70.2% of Exclusive Economic Zones but changes varied spatially and temporally in alignment with confinement measures. Global declines peaked in April, with a reduction in traffic occupancy of 1.4% and decreases found across 54.8% of the sampling units. Passenger vessels presented more marked and longer lasting decreases. A regional assessment in the Western Mediterranean Sea gave further insights regarding the pace of recovery and long-term changes. Our approach provides guidance for large-scale monitoring of the progress and potential effects of COVID-19 on vessel traffic that may subsequently influence the blue economy and ocean health. The COVID-19 response has led to unparalleled changes in the functioning of human society, from travel restrictions to changes in consumption. Here the authors use high resolution satellite data to track the global reduction in marine traffic during the pandemic, and more recent hints of recovery to pre-lockdown levels.
