Ships in Shallow Waters Found to Release Alarming Methane Emissions
New research highlights alarming methane emissions from ships in shallow waters.
Key Points
- • Ships in shallow waters can cause significant methane emissions.
- • Methane is a greenhouse gas much more potent than carbon dioxide.
- • Emissions can reach levels up to 20 times higher than surrounding areas.
- • International plans for further measurements in major ports are underway.
Researchers at Chalmers University of Technology and the Swedish Meteorological and Hydrological Institute (SMHI) have made a significant discovery regarding methane emissions linked to ships operating in shallow waters. Their study reveals that these vessels can cause methane emissions up to 20 times higher than the surrounding areas due to pressure changes at the seabed triggered by ship movements.
Methane is a potent greenhouse gas, significantly more impactful than carbon dioxide in terms of contributing to climate change. This finding underscores a previously hidden source of emissions in maritime environments, with implications for environmental policy and climate strategies. The alarming levels of methane released have drawn international attention, prompting researchers to plan further measurements in major ports worldwide. Oceanographer Amanda Nylund emphasized the need for continued research to understand the broader environmental impacts of maritime operations on climate change.
As global shipping continues to expand, the insights from this research highlight an urgent call to analyze and mitigate the environmental effects of ships to better address climate change initiatives.
