Quantification of methane fluxes and authigenic carbonate formation at cold seeps along the continental margin offshore Costa Rica: A numerical modeling approach [PDF]
The expulsion of liquids, gases and fluids at continental margins covers a wide range of processes including not only mud volcanism, mud diapirism and gas flares, but also continuously seeping methane-rich fluids leading to cold vent sites and even ...

Chemotrophic Microbial Mats and Their Potential for Preservation in the Rock Record [PDF]
Putative microbialites are commonly regarded to have formed in association with photosynthetic microorganisms, such as cyanobacteria. However, many modern microbial mat ecosystems are dominated by chemotrophic bacteria and archaea.

Physical controls of cold seep methane emission [PDF]
In situ methane emission measurements from sediments are combined with water column backscatter anomalies recorded with an Acoustic Doppler Current Profiler (ADCP) integrated on a benthic observatory. During cruise SO1911 to the Hikurangi Margin (New Zealand), the Fluid Flux Observatory (FLUFO) was deployed at a cold seep site at Omakere Ridge.

ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...

Evaluation of electrolyzed water to control fungal trunk pathogens in grapevine nurseries
Electrolyzed water treatments could have promising applications in the grapevine nursery process to prevent or reduce infections caused by fungal trunk pathogens on grapevine propagation material. Abstract BACKGROUND Grapevine producers demand solutions to control fungal trunk pathogens (FTPs) in nurseries.

The sediment-water interfaces of cold seeps play important roles in nutrient transportation between seafloor and deep-water column. Microorganisms are the key actors of biogeochemical processes in this interface.

Relatively little is known about the taxonomy and ecology of deep-sea nematode species inhabiting cold seep habitats. The available data show that cold seep nematode communities are typically characterized by low diversity and are often dominated by a ...

Contrastive Self‐Categorization as a Resource for Defending Cultural Stereotypes
This study explores how speakers defend morally sanctionable cultural stereotypes from challenges in adult second language classrooms. Within the conversation analysis and membership categorization analysis frameworks, I examine two extended video‐recorded class discussions in which students maintain face‐threatening, stereotypical portrayals of ...
