Cold seep - Wikipedia
A cold seep (sometimes called a cold vent) is an area of the ocean floor where seepage of fluids rich in hydrogen sulfide, methane, and other hydrocarbons occurs, often in the form of a brine pool. Cold does not mean that the temperature of the seepage is lower than that of the surrounding sea water; on the contrary, its temperature is often ...
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. At these seep sites, the escaping fluid or gas is most often found to have temperatures close to that of the surrounding seawater. They are referred ...
Cold seeps are potential hotspots of deep-sea nitrogen loss
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...
冷泉(海洋科学)_百度百科
冷泉(cold seep)是指以水、甲烷和其他碳氢化合物、硫化氢、细粒沉积物为主要成分的流体以喷涌或渗漏的方式从海底溢出的地区 [1]。 冷泉的“冷”与深海热液的“热”相对,但流体的实际温度与周围海水接近,约2~4℃。 主要分布在被动陆缘和主动陆缘斜坡海底沉积面之下 [2]。 探索历史. 1983年,美国科学家Charles Paull首次在加利福尼亚州蒙特利尔海湾(Monterery Bay)水深3200m的海底发现了富含天然气和硫化氢的流体,该流体的温度与周围海水接近,为了区别于 …
Education: Themes: Cold Seeps: NOAA Ocean Exploration
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.
Marine Cold Seeps: Background and Recent Advances
2018年4月6日 · Marine cold seeps are windows into different depth levels of the submerged geosphere. Subduction zones and organic-rich passive margins host most of the world’s cold seeps. The source of seep fluids ranges from 10s of meters (groundwater aquifers) to 10s of km (subducted oceanic plates) below the seafloor.
Cold Seep Systems - SpringerLink
2017年7月19日 · ‘Cold’ seeps (or cold venting) are seafloor manifestations of fluid migration through sediments from the subsurface to the seabed and into the water column until they may reach the atmosphere. They may be generated by the activity of microbes in shallow sediments or by processes occurring deeper in the sediments (thermogenic).
Cold seep systems in the South China Sea: An overview
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.
Deep sea sediments associated with cold seeps are a subsurface ...
2021年3月1日 · Here, we probed metagenomes from seven geographically diverse cold seeps across global oceans to assess viral diversity, virus–host interaction, and virus-encoded auxiliary metabolic genes...
Cold Seep - an overview | ScienceDirect Topics
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. Cold seeps occur over fissures on the seafloor caused by tectonic activity.
