The spread of coronavirus (COVID-19) caused an unprecedented implementation of lockdown measures across world's nations. Veneto Region, located in North-Eastern Adriatic Sea was one of the first maritime regions in Italy and Europe subjected to progressive lockdown restrictions. We systematically analyse the effects of national lockdown policies on maritime settings of the region using Automated Identification System (AIS) data from fishing vessels, passenger ships, tanker and cargo vessels collected through the Aqua Alta Oceanographic Tower (AAOT). We derive consequences on vessel activities during the March-April 2020 lockdown, by using a data-driven, comparative spatio-temporal analysis of vessel trajectories. Results show that compared to the same period of 2017, vessel activity were reduced by 69% during the lockdown, fishing activities reduced by 84% and passenger traffic by 78%. We register a restart of fishing activity in the third week of April 2020. We suggest that the presented conceptual and spatial assessment protocol can guide future research on environmental and socio-economic effects of COVID-19 on marine realms and contribute to further interdisciplinary research with other marine scientific fields.
新冠病毒（COVID-19）的传播导致世界各国前所未有地实施了封锁措施。威尼托地区位于东北亚得里亚海，是意大利和欧洲首批受到逐步封锁限制的海洋地区之一。我们使用从 Aqua Alta 海洋塔（AAOT）收集的渔船、客船、油轮和货船的自动识别系统（AIS）数据，系统地分析了国家封锁政策对该地区海洋环境的影响。我们通过对船舶轨迹进行数据驱动的、比较的时空分析，得出了 2020 年 3 月至 4 月封锁期间船舶活动的后果。结果表明，与 2017 年同期相比，封锁期间船舶活动减少了 69%，渔业活动减少了 84%，客运量减少了 78%。我们记录到 2020 年 4 月的第三周，渔业活动开始恢复。我们建议，所提出的概念和空间评估协议可以指导未来对 COVID-19 对海洋领域的环境和社会经济影响的研究，并有助于与其他海洋科学领域进行进一步的跨学科研究。
