Das Seetang an Sandy Shores wäscht mehr als nur verrottet. Eine neue Studie ergab, dass sie Sauerstoff-tolerante Mikroorganismen treibt, die Methan in die Luft pumpen. Methan wurde in flachen Küstengewässern in „Übersättigungskonzentrationen“ konsequent gefunden, in einigen Fällen fast 1.900 Mal mehr.

I’ve linked to the news release in the post above. In this comment, for those interested, here’s the link to the peer reviewed journal article:

From the linked article:

**Seaweed washing onto sandy shores does more than rot. A new study found that it fuels oxygen-tolerant microorganisms that pump methane into the air**, overturning a long-held scientific assumption about coastal ecosystems and their climate role.

**Methane was consistently found in shallow coastal waters at “supersaturation” concentrations massively higher than what would normally be expected if the water was just in balance with the air. In some cases, nearly 1,900 times more**. Methane production was driven by methanogenic microbes that can survive and remain active even after repeated exposure to oxygen – a phenomenon previously thought to be impossible. It had been thought that methanogenic archaea in coastal ecosystems couldn’t survive being exposed to oxygen.
