Element Variation in a Clam Shell and its Implications for Cold Seep Irregular Eruptions: Calyptogena Sp. In the Haima Cold Seep

SSRN Electronic Journal, 2022
Cold seep is characterized by methane-rich fluids released from subsurface reservoirs, and it sustains the chemosynthetic ecosystems on the seafloor. Previous studies suggest that the activity of cold seep could affect the seawater chemistry and ambient temperature.

Evidence for intense REE scavenging at cold seeps from the Niger Delta margin

Earth and Planetary Science Letters, 2011
International audienceFor many trace elements, continental margins are the location of intense exchange processes between sediment and seawater, which control their distribution in the water column, but have yet to be fully understood.

Macro-Ecology of Gulf of Mexico Cold Seeps

Annual Review of Marine Science, 2009
Shortly after the discovery of chemosynthetic ecosystems at deep-sea hydrothermal vents, similar ecosystems were found at cold seeps in the Gulf of Mexico. Over the past two decades, these sites have become model systems for understanding the physiology of the symbiont-containing megafauna and the ecology of seep communities worldwide.

Methods for the Study of Cold Seep Ecosystems

2010
The discovery of huge subsurface reservoirs of methane in the form of gas hydrate, has fueled the interest in the associated seep ecosystems and their role as barriers against this greenhouse gas. Technological advances in high-resolution mapping and optical imaging, as well as in situ chemical analyses of the deep seafloor have helped to reveal the ...

Reproduction and dispersal at vents and cold seeps

Journal of the Marine Biological Association of the United Kingdom, 1999
Reproductive cycles are determined from samples taken at regular intervals over a period of time related to the assumed periodicity of the breeding cycle. Fiscal, ship time and sampling constraints have made this almost impossible at deep-sea vents and seeps, but there is an accumulating mass of data that cast light on these processes.

Methanotrophic bacteria in cold seeps of the floodplains of northern rivers

Microbiology, 2013
Small mud volcanoes (cold seeps), which are common in the floodplains of northern rivers, are a potentially important, although poorly studied sources of atmospheric methane. Field research on the cold seeps of the Mukhrina River (Khanty-Mansiysk Autonomous okrug, Russia) revealed methane fluxes from these structures to be orders of magnitude higher ...

Effects of microplastics on cold seep sediment prokaryotic communities

Environmental Pollution
Cold seep sediments are an important reservoir of microplastics (MPs) whose impact on the structure and function of prokaryotic community is not well understood. In this study, the impact of 0.2% and 1% (w/w) polyethylene (PE), polystyrene (PS), and polypropylene (PP) MPs on the cold seep sediment prokaryotic community was investigated in a 120-day ...
