CAGE15-6 Cruise Report: Arctic gas hydrate studies Open
RV Helmer Hanssen is the only vessel operating so far north (81 N) in October. One of the research questions addressed during this cruise is: Where do gas hydrate exist in the seabed and how much methane does it actually release? The CAGE …

CAGE20-3 Cruise Report: Geochemical and Sedimentological Investigation into Ingøydjupet, Håkon Mosby Mud Volcano and the Sorvestnaget Sand Waves Open
This expedition ran between July 28 and August 3 2020, targeting three sites in the Barents Sea, an area of glacial landforms in Ingøydjupet trough, the Håkon Mosby Mud Volcano and the Sorvestnaget Sand Wave area. Our short but productive …

Geological controls of giant crater development on the Arctic seafloor Open
Active methane seepage occurs congruent with a high density of up to 1 km-wide and 35 m deep seafloor craters (>100 craters within 700 km 2 area) within lithified sedimentary rocks in the northern Barents Sea. The crater origin has been hy…

Methane hydrate mobilization by ice stream erosion during the last glacial Open
<p>During the past ~2.6 Ma, some 30 glaciations have caused episodic high pressure and low temperature conditions and forced growth and decay of extensive subglacial methane hydrate accumulations globally. Research on Arctic methane …

Fluid dynamics at the base of hydrate-bearing sediments at the Vestnesa Ridge inferred from 5 years of high-resolution 4D seismic surveying Open
<p>The transition from gas hydrate to gas-bearing sediments at the base of the hydrate stability zone (BHSZ) is commonly identified on seismic data as a bottom-simulating reflection (BSR). At this boundary, phase transitions driven b…

3D and 4D seismic investigations of fluid flow and gas hydrate systems Open
Using the state-of-the-art high resolution P-Cable 3D seismic system, in this thesis we (1)\nstudy the shallow strata (<1km below seabed) and describe the geological controls and\ndriving mechanisms for fluid leakage at two sites in the no…

Geological Controls on Fluid Flow and Gas Hydrate Pingo Development on the Barents Sea Margin Open
In 2014, the discovery of seafloor mounds leaking methane gas into the water column in the northwestern Barents Sea became the first to document the existence of nonpermafrost‐related gas hydrate pingos (GHPs) on the Eurasian Arctic shelf.…

Meter-Scale 3D Seismic Data for High-Resolution Site Characterization Open
High-resolution 3D site characterization can deliver reliable quantitative property volumes of the subsurface when based on seismic data able to image meter-sized objects. Following the theoretical analysis of seismic wave propagation in t…

Replication Data for: Geological controls on fluid flow and gas hydrate pingo development on the Barents Sea margin. Open
The data includes two high-resolution P-Cable 3D seismic datasets processed in 2016 from Storfjordrenna, Barents Sea, used in the article published by G-Cubed "Geological controls on fluid flow and gas hydrate pingo development on the Bare…

Monitoring Of CO2 Leakage Using High-Resolution 3D Seismic Data – Examples From Snøhvit, Vestnesa Ridge And The Western Barents Sea Open
Injection of CO2 in subsurface reservoirs may cause overburden deformation and CO2 leakage. The aim of this study is to apply technologies for detection and monitoring of CO2 leakage and deformation above the injection reservoirs. The exam…

Repeatability of high-resolution 3D seismic data Open
High-resolution 4D (HR4D) seismic data have the potential for improving the current state-of-the-art in detecting shallow ([Formula: see text] below seafloor) subsurface changes on a very fine scale (approximately 3–6 m). Time-lapse seismi…

Geophysical and geochemical controls on the megafaunal community of a high Arctic cold seep Open
Cold-seep megafaunal communities around gas hydrate mounds (pingos) in the western Barents Sea (76∘ N, 16∘ E, ∼400 m depth) were investigated with high-resolution, geographically referenced images acquired with an ROV and towed camera. Fou…

Variations in Gas and Water Pulses at an Arctic Seep: Fluid Sources and Methane Transport Open
Methane fluxes into the oceans are largely dependent on the methane phase as it migrates upward through the sediments. Here we document decoupled methane transport by gaseous and aqueous phases in Storfjordrenna (offshore Svalbard) and pro…
