According to the United Nations Environment Programme (UNEP), one of the recent large-scale accidental releases of methane gas into the ocean occurred in Nord Stream.
– In September 2022, leaks were discovered in the Nord Stream 1 and Nord Stream 2 gas pipelines in the Baltic Sea.
– These pipelines carried natural gas (primarily methane) from Russia to Europe. The leaks resulted in a massive release of methane into the atmosphere and the surrounding ocean.
– UNEP and other organizations reported on the scale and environmental implications of this event, describing it as potentially the largest single release of methane from a single source ever recorded.
Exxon Valdez and Atlantic Empress were major oil spills. Deepwater Horizon was also primarily an oil spill, although there was also associated natural gas release. The Nord Stream incident is distinguished by being a massive release *specifically of methane* from undersea gas infrastructure.
