Sea grasses play an important role in the global carbon cycle. In this video, SINA SCHORN investigates the mechanisms by which the Mediterranean sea grass Posidonia oceanica stores carbon while emitting methane. Employing methods including flex measurements and substrate addition experiments, among Schorn’s most important findings is the fact that sediments in which sea grasses have died off can continue to emit methane for decades. This research thus highlights the importance of preserving sea grasses while providing the methodological foundation for further work on other sea grass species.
