Summary: During the first half of 2020, the authors quantify and map global changes in marine traffic. There were declines in 70.2% of EEZs, however the changes varied regionally and temporally in accordance with confinement measures. Global losses peaked in April, with a 1.4% drop in traffic occupancy and drops detected in 54.8% of the sample units.
