Methane oxidation and emission in Lake Lugano (Southern Switzerland) : a lipid biomarker and isotopic approach [PDF]

, 2015
Methane is an important greenhouse gas in Earth's atmosphere. The sources of atmospheric methane are largely biogenic, being produced under anoxic conditions by methanogenic Archaea.

Methane hydrate stability and anthropogenic climate change [PDF]

Biogeosciences, 2007
Methane frozen into hydrate makes up a large reservoir of potentially volatile carbon below the sea floor and associated with permafrost soils. This reservoir intuitively seems precarious, because hydrate ice floats in water, and melts at Earth surface ...

Role of Warming in Destabilization of Intrapermafrost Gas Hydrates in the Arctic Shelf: Experimental Modeling

Geosciences, 2019
Destabilization of intrapermafrost gas hydrates is one of the possible mechanisms responsible for methane emission in the Arctic shelf. Intrapermafrost gas hydrates may be coeval to permafrost: they originated during regression and subsequent cooling and

Rapid Joule‐Heating‐Induced Non‐Equilibrium Exsolution in Perovskite Oxides for Enhanced Photothermal CO2 Methanation

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Rapid Joule heating induces Ni—Fe exsolution from perovskite oxides, forming Ni–Fe/oxide heterointerfaces that enhance photothermal CO2 methanation activity and selectivity. Achieving selective CO2 methanation under photothermal conditions requires catalysts capable of maintaining non‐equilibrium interfacial states that balance reduction and oxidation ...

Diversity and Spatial Distribution of Prokaryotic Communities Along A Sediment Vertical Profile of A Deep-Sea Mud Volcano Maria G. Pachiadaki & Argyri Kallionaki [PDF]

, 2011
We investigated the top 30-cm sediment prokaryotic community structure in 5-cm spatial resolution, at an active site of the Amsterdam mud volcano, East Mediterranean Sea, based on the 16S rRNA gene diversity.

Methane Hydration‐Shell Structure and Fragility

Angewandte Chemie, 2018
AbstractThe influence of oily molecules on the structure of liquid water is a question of importance to biology and geology and many other fields. Previous experimental, theoretical, and simulation studies of methane in liquid water have reached widely conflicting conclusions regarding the structure of hydrophobic hydration‐shells.

A machine learning assisted method for rapidly annotating benthic megafauna in large volumes of marine imagery

Limnology and Oceanography: Methods, EarlyView.
Abstract Recent technological advancements have rapidly expanded our capacity for collecting image data in the marine environment, but processing images into meaningful ecological metrics remains a manual, time‐consuming, and biased process. This is particularly challenging with electro‐optical cabled imaging systems which generate images at a rate ...
