  • Ships trigger high and unexpected emissions of the greenhouse gas methane/
  • A Chalmers-led study shows that ship passages can trigger clear pulses of high methane fluxes from the water to the atmosphere. The emissions are caused by pressure changes and mixing of the water mass. The researchers observed twenty times higher methane emissions in the fairway compared to nearby undisturbed areas. Despite the fact that methane is a greenhouse gas that is 27 times as powerful as carbon dioxide, these emissions are often overlooked with today's measurement methods.
