New Antarctic methane seeps and what they might mean - Our Changing World
Update: 2024-12-18
Description
New methane seeps are being discovered in Antarctica, some now appearing in areas that researchers have been monitoring for years. These are areas on the seafloor where methane gas escapes out from under the ground through fissures or cracks. What is the extent of the seeps? How large is the gas reservoir they are being fed from? How much methane is escaping from the sea into the air? Why now? And does this have implications for further warming the planet? A team of NIWA scientists are racing to find answers.
Guests:
- Dr Sarah Seabrook, NIWA
- Dr Leigh Tait, NIWA
