Seismic monitoring of sub-seafloor fluid processes in the Haima cold seep area using an Ocean Bottom Seismometer (OBS)

open access: yesEarth and Planetary Physics, 2023
The use of ocean bottom seismometers provides an effective means of studying the process and the dynamic of cold seeps by continuously recording micro-events produced by sub-seafloor fluid migration. We deployed a four-component Ocean Bottom Seismometer (

Thermal Energy Generation in the Earth [PDF]

open access: yes, 2014
We show that a recently introduced class of electromagnetic composite particles can explain some discrepancies in observations involving heat and helium released from the earth. Energy release during the formation of the composites and subsequent nuclear

Physical controls of cold seep methane emission [PDF]

open access: yesOCEANS 2009-EUROPE, 2009
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.

Research progress and current status of dynamic wave propagation characteristics in rock mass: A review

open access: yesDeep Underground Science and Engineering, EarlyView.
This review elucidates the velocity–dispersion–attenuation coupling mechanisms of wave propagation in rock masses, compares six representative models, and reveals how pressure, temperature, mineral composition, and anisotropy jointly control dynamic responses in complex geological media.

Methane seep carbonates yield clumped isotope signatures out of equilibrium with formation temperatures

open access: yesNature Communications, 2016
The geochemistry of methane cold seep carbonates is often used to reconstruct environmental conditions. Loyd et al. find disequilibrium clumped isotope compositions in modern seep carbonates that suggest temperatures up to 50°C too high, raising doubt on

Elevated methane alters dissolved organic matter composition in the Arctic Ocean cold seeps

open access: yesFrontiers in Earth Science, 2023
Cold seeps release methane (CH4) from the seafloor to the water column, which fuels microbially mediated aerobic methane oxidation (MOx). Methane-oxidising bacteria (MOB) utilise excess methane, and the MOB biomass serves as a carbon source in the food ...

Benthic invertebrate assemblages and sediment characteristics [PDF]

open access: yes, 2009
Cold seep ecosystems in the deep sea are fuelled by chemosynthetic processes based on methane emission to the sediment surface from gas hydrate disassociation, methanogenesis or thermogenic processes.

Planktonic and sediment-associated aerobic methanotrophs in two seep systems along the North American margin [PDF]

open access: yes, 2008
Methane vents are of significant geochemical and ecological importance. Notable progress has been made towards understanding anaerobic methane oxidation in marine sediments, however, the diversity and distribution of aerobic methanotrophs in the water ...

User‐Relevant Climate Indices and Associated Uncertainties From Transient Convection‐Permitting Climate Model Projections

open access: yesInternational Journal of Climatology, EarlyView.
A transient ensemble of convection‐permitting climate simulations is used to compute bias‐corrected user‐relevant climate indices for Germany under recent and future climate conditions, both considering high spatial resolution and uncertainty estimations. For high temperature indices, a clear increase is observed, for example, for hot days and tropical
