Cold seeps play a critical role in moving older carbon stored in the seafloor into the ocean, where it is consumed by bacteria and other microbes. Locating and studying seeps will expand our understanding of how seep sites impact oceanic, and possibly atmospheric, processes.

Cold seeps are locations where hydrocarbon-rich fluid seeps up from below the seafloor, often as methane or hydrogen sulfide. Cold seeps have been found to support significant chemosynthetic communities, which produce food using chemical energy.

2020年3月19日 · The discovery of life at vents and seeps revolutionized understanding of how and where life can exist on Earth. The organisms that thrive at deep-sea vents and seeps have to survive freezing cold, perpetual darkness, high-pressure, and toxic chemicals.

Cold seeps are places throughout the global ocean where chemicals like hydrogen sulfide, methane, and other hydrocarbon-rich fluids and/or gases escape from cracks or fissures in the ocean floor.

2018年4月6日 · Marine cold seeps provide windows into different depth levels of the geosphere where transfer processes and reactions are active. Cold seeps emit material back into the ocean and leave characteristic footprints on the seafloor.

2025年2月14日 · Cold seeps are specialized marine environments primarily located along continental slopes and subduction zones, where subsurface fluids rich in hydrogen sulfide and hydrocarbons, such as...

2012年12月19日 · A cold vent (sometimes called a cold seep) is an area of the ocean floor where hydrogen sulfide, methane, and other hydrocarbon-rich fluid seepage occurs, often in the form of a brine pool.

2017年7月19日 · In this chapter we attempt to address cold seep systems with an emphasis on their origin, evolution, form, and occurrence, approaching them primarily from their morphologies and the acoustic character of the seafloor and near bottom erupted sediments.

2023年2月3日 · Cold (or marine) seeps are locations where hydrocarbon-rich fluid seeps up from below the seafloor, often as methane or hydrogen sulfide. Hydrothermal vents are openings on the ocean floor from which magma-heated, mineral …

2018年12月1日 · In this review, we describe the cold seep systems of the SCS with an emphasis on seafloor manifestations, fluid sources, biogeochemical processes, and macroecology. Seafloor features associated with seeps include mud volcanoes, pockmarks, and carbonate deposits.
