Greenpeace placed a peace flag on one of the sabotaged Nord Stream pipelines at the end of September, to mark the end of a campaign of water and soil sampling in the area of the explosions in the Baltic Sea.
The flag was lowered by an underwater drone to symbolize hope for a future peaceful energy supply through renewable sources, Greenpeace said in a press release. The underwater shots taken by the drone also document the extent of the destruction of the pipelines caused by the explosions.
The Greenpeace ship “Beluga II” then returned to Germany where the collected soil and water samples will be analyzed in the coming weeks.
There have been at least two major methane emissions from oil and gas infrastructure since last December, including the rupture of the Nord Stream pipeline system under the Baltic Sea.
The World Meteorological Organization said in October that last year’s jump in methane concentrations was the largest since records began in 1983 and followed another record year in 2020.
