正文(英文) | Ship movements on the world's oceans dropped in the first half of 2020 as Covid-19 restrictions came into force, a new study shows. Researchers used a satellite vessel-tracking system to compare ship and boat traffic in January to June 2020 with the same period in 2019. The study, led by the University of Exeter (UK) and involving the Balearic Islands Coastal Observing and Forecasting System and the Mediterranean Institute for Advanced Studies (both in Spain), found decreased movements in the waters off more than 70 per cent of countries. Global declines peaked in April 2020, but by June -- as Covid restrictions were eased in many countries -- ship movements began to increase. "As lockdowns came into force, we heard stories and began to see early research findings that suggested reduced boat movements had allowed some marine ecosystems to recover," said lead-author Dr David March of the Centre for Ecology and Conservation on Exeter's Penryn Campus in Cornwall. "There were reports of clearer water in Venice's canals, and a study showed a reduction in underwater noise at Vancouver." Professor Brendan Godley, who leads the Exeter Marine research group, added: "The effects of ships and boats -- from noise and pollution to fishing and collisions with animals -- have a major impact on marine ecosystems across the world. "Our study aimed to measure the impact of Covid on this traffic, and we are continuing to monitor this as the restrictions on human activity continue to change. "Quantifying the changes in human activities at sea paves the way to research the impacts of Covid-19 on the blue economy and ocean health." The study found:
"The long-term trend is for increased global ship movements, so a modest decrease may represent a more significant reduction compared to the amount of traffic we would otherwise have seen," Dr March concluded. Near real-time vessel traffic data was provided by exactEarth and Marine Traffic. Funding for the study came from a Marie Sk?odowska-Curie grant under the European Union's Horizon 2020 programme, the Natural Environment Research Council, the Waterloo Foundation, and the Darwin Initiative. The paper, published in the journal Nature Communications, is entitled: "Tracking the global reduction of marine traffic during the COVID-19 pandemic."
