Spatial Changes in Gas Transport and Sediment Stiffness Influenced by Regional Stress: Observations From Piezometer Data Along Vestnesa Ridge, Eastern Fram Strait

A. Plaza-Faverola et al.

Summary: Gas transport in deep ocean environments is controlled by pressure regime and can occur through pores, faults, fractures, and diffusion. This study examines the pressure conditions along the Vestnesa Ridge in the Fram Strait using piezometer data, geotechnical tests, and sediment core analyses. The results show a decrease in induced pore pressure and sediment stiffness upon piezometer penetration, suggesting a mechanical damage to the upper sediment layers due to variations in gas diffusion rates and exsolution. These findings, along with geophysical data and sediment core analyses, indicate a shift from advection-dominated to diffusion-dominated fluid flow system, influenced by sedimentary faults. Understanding gas transport mechanisms is important for studying gas hydrate inventories, seepage phenomena, and sediment deformations in deep ocean settings.

Evidence of Arctic methane emissions across the mid-Pleistocene

Giuliana Panieri et al.

Summary: During the Pleistocene, there were significant changes in Earth's climate, leading to increased ice volume and methane leakage. Borehole data from the Arctic-Atlantic gateway region reveals three main seafloor leakage episodes prior to and during the mid-Pleistocene transition. Combining this data with hydrate stability modeling, it is proposed that tectonic stress changes associated with ice volume changes controlled episodic methane leakages.

Impact of Gas Saturation and Gas Column Height at the Base of the Gas Hydrate Stability Zone on Fracturing and Seepage at Vestnesa Ridge, West-Svalbard Margin

Hariharan Ramachandran et al.

Summary: This study uses simulations to determine the amount of gas required to open preexisting fractures from the base of the gas hydrate stability zone to the seafloor in the Vestnesa Ridge. The results indicate that neglecting capillary pressure can lead to overprediction of gas column size and erroneous predictions of maximum gas vent volume. The study also suggests that variations in regional stress regime can affect venting across the ridge.

Origin and Periodic Behavior of Short Duration Signals Recorded by Seismometers at Vestnesa Ridge, an Active Seepage Site on the West-Svalbard Continental Margin

P. Domel et al.

Summary: This study analyzed the characteristics and temporal occurrence of short duration events (SDEs) using ocean-bottom seismometers (OBSs) at Vestnesa Ridge. The results showed that SDEs have periodic patterns related to solar and lunar cycles, and tides have a partial control on SDEs recorded over 10 months. The study also suggested that SDEs at Vestnesa Ridge may be related to the dynamics of the methane seepage system.

Glacially Induced Stress Across the Arctic From the Eemian Interglacial to the Present-Implications for Faulting and Methane Seepage

R. Vachon et al.

Summary: This study investigates the evolution of glacial stress field in the Arctic and its impact on near-surface geological processes, such as methane seepage and faulting. The findings suggest that glacial stresses can have significant effects on the upper lithosphere, especially in areas with thick ice cover.

Reassessment of Hydrate Destabilization Mechanisms Offshore West Svalbard Confirms Link to Recent Ocean Warming

Summary: This study investigates the impact of temperature and sea level changes on methane hydrates on the upper continental slope west of Svalbard. Two contrasting hypotheses are tested, and it is concluded that recent ocean warming plays a critical role in hydrate dissociation in this area.

Reassessment of Hydrate Destabilization Mechanisms Offshore West Svalbard Confirms Link to Recent Ocean Warming

Akash Trivedi et al.

Summary: This study investigated the mechanisms by which the stability of methane hydrates at the UCS off west Svalbard is influenced by changes in bottom water temperature and sea level. The simulation results suggest that long-term sea level fall will progressively decrease the hydrate stability zone, while a sudden rise in bottom water temperature increases the likelihood of hydrate dissociation.

Summary: The study found significant changes in bottom water temperature and oxygen isotopes in the Nordic Seas during glacial Greenland Interstadial and Greenland Stadial events, revealing different environmental conditions. The results suggest that during some Stadials and Heinrich Stadials, deep water generation was reduced, allowing the spreading of Atlantic subsurface water to the Nordic Seas.

The Plio-Pleistocene seepage history off western Svalbard inferred from 3D petroleum systems modelling

Matthias Daszinnies et al.

Summary: The study reveals methane seepage off the coast of Svalbard and uses a high-resolution 3D petroleum systems model to understand the accumulation of gaseous hydrocarbons in sedimentary sequences underneath the pockmark system on the Vestnesa Ridge. The gas leakage to the seafloor is attributed to fault corruption of the hydrocarbon traps rather than excess pore fluid pressure. The repeated seepage events over the past 160,000 years can be explained by glacial forebulge uplift, subsidence, and fracture re-activation mechanisms associated with the Svalbard-Barents Sea ice sheet.

Ice-sheet melt drove methane emissions in the Arctic during the last two interglacials

P-A Dessandier et al.

Summary: The melting of Circum-Arctic glacial ice may lead to the release of geological methane, amplifying the retreat of ice sheets. Evidence suggests that during the terminations of the last two glacial periods, methane was released from shallow gas reservoirs along the margins of western Svalbard, potentially due to the destabilization of ice sheets.

Interactions between deep formation fluid and gas hydrate dynamics inferred from pore fluid geochemistry at active pockmarks of the Vestnesa Ridge, west Svalbard margin

W. -L. Hong et al.

Summary: The seafloor seepage sites along the Vestnesa Ridge off west-Svalbard have been a natural laboratory for studying fluid flow and gas hydrate dynamics. The research conducted in 2016 revealed unique characteristics of gas hydrates, hinting at temperature modification at great depths. Analysis of pore fluid composition also showed the presence of high chloride concentrations, high B/Cl ratios, and isotopic signatures indicating methane supply and decomposition dynamics.

A Continuous Seismostratigraphic Framework for the Western Svalbard-Barents Sea Margin Over the Last 2.7 Ma: Implications for the Late Cenozoic Glacial History of the Svalbard-Barents Sea Ice Sheet

Nikolitsa Alexandropoulou et al.

Summary: A high-resolution, continuous seismostratigraphic framework is presented here, connecting the western Svalbard-Barents Sea margin for the first time and covering approximately 2.7 million years. By establishing reliable age fix-points and utilizing a large 2-D seismic database, a consistent chronology is extended southwards along the margin. This new stratigraphic framework divides the seismic stratigraphy into three units and identifies three phases of glacial development along the continental margin.

Deep Ocean Storage of Heat and CO2 in the Fram Strait, Arctic Ocean During the Last Glacial Period

Mohamed M. Ezat et al.

Summary: The study found that during most of the late glacial period, Atlantic water only penetrated into the northern Nordic Seas, forming a buried subsurface Atlantic intermediate water layer reaching at least 2600 meters deep. Comparing carbonate ion concentration and nitrogen isotope records, it suggests that the total terrestrial CO2 release during the carbon input event was low, slow, or directly to the atmosphere.

Latitudinal variability in the Quaternary development of the Eurasian ice sheets-Evidence from the marine domain

Berit Oline Hjelstuen et al.

Summary: By compiling data on sediment volumes, sedimentation rates, and chronology of Quaternary sediment packages along the entire marine margin of the Eurasian ice sheets, the development of the Eurasian ice sheets can be divided into three phases. The data suggests that at the beginning of the Quaternary, sedimentation rates increased significantly, and the Kara-Barents Sea-Svalbard Ice Sheet was already quite large.
