Insights into prokaryotic communities and their potential functions in biogeochemical cycles in cold seep

mSphere
Microorganisms are significant drivers of organic matter mineralization and are essential in marine biogeochemical cycles. However, the variations and influencing factors in prokaryotic communities from cold-seep sediments to the water column and the ...

Changing redox conditions at cold seeps as revealed by authigenic carbonates from Alaminos Canyon, northern Gulf of Mexico

, 2011
Anaerobic oxidation of methane in anoxic sediments at cold seeps often leads to formation of authigenic carbonates close to the seafloor along continental margins.

Microbial community structure associated to Arctic cold seeps [PDF]

, 2021
Cold seeps are locations on the seafloor where CH4 migrates from reservoirs below sediments towards the atmosphere, sustaining thereby a high microbial and macrofaunal biomass and a diversity contrasting from the surrounding seafloor.

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Mats of psychrophilic thiotrophic bacteria associated with cold seeps of the Barents Sea [PDF]

, 2012
This study investigated the bacterial diversity associated with microbial mats of polar deep-sea cold seeps. The mats were associated with high upward fluxes of sulfide produced by anaerobic oxidation of methane, and grew at temperatures close to the ...

‘Elbow grease and yellow soap’: Housework time in working‐class households in late‐nineteenth and early twentieth‐century Britain

The Economic History Review, EarlyView.
Abstract Housework is central to feminist calls for recognition of women's work, economic histories explaining the sexual division of labour, and claims regarding the progressive role of scientific knowledge. Yet little is known about the time it actually took. We address this lacuna.

Reconnaissance‐Scale Methods for the Identification of Groundwater Discharge to Streams

Groundwater Monitoring &Remediation, EarlyView.
Abstract Identifying groundwater discharge locations is critical for understanding and monitoring groundwater contributions to streams in terms of water quantity and quality. Streams and rivers are under increasing strain from factors, including increased urbanization, agricultural land use, groundwater extraction, and climate change, which can alter ...

Community study of tubeworm-associated epizooic meiobenthos from deep-sea cold seeps and hot vents [PDF]

, 2012
The permanent metazoan meiofauna associated with vestimentiferan tubeworm aggregations from hydrocarbon seeps of the upper Louisiana slope in the Green Canyon (similar to 550 m) and the lower slope in Atwater Valley (similar to 2200 m) of the Gulf of ...

Deep-sea viral diversity and their role in host metabolism of complex organic matter

Nature Communications
Viruses exert a pervasive influence on biogeochemical cycles in deep-sea ecosystems. Cold seeps and seamounts, globally distributed across the oceans and harboring diverse microbial communities, remain largely unexplored regarding their viral inhabitants

Dispersion and fate of methane emissions from cold seeps on Hikurangi Margin, New Zealand

Frontiers in Earth Science
The influence of cold seep methane on the surrounding benthos is well-documented but the fate of dissolved methane and its impact on water column biogeochemistry remains less understood.
