Cold seep ecosystem
WebDec 1, 2024 · Cold seeps are seafloor manifestations of methane-rich fluid migration from the sedimentary subsurface to the seabed and into the water column, and ultimately some of the methane may even reach the atmosphere (e.g., Boetius and Wenzhöfer, 2013, Suess, 2014, Ceramicola et al., 2024 ). WebJan 23, 2024 · A cold seep is one of the typical deep-sea chemical energy ecosystems and a hotspot for studying unique life processes and biogeochemical cycles in the deep sea. Macrofauna, which is one of the most important components of the cold seep ecosystem, has not been thoroughly studied.
