    • Hydrate occurrence in Europe: A review of available evidence 

      Minshull, Timothy A.; Marin-Moreno, Hector; Betlem, Peter; Bialas, Joerg; Bünz, Stefan; Burwicz, Ewa; Cameselle, Alejandra L.; Cifci, Gunay; Giustiniani, Michela; Hillman, Jess I.T.; Hölz, Sebastian; Hopper, John R.; Ion, Gabriel; Leon, Ricardo; Magalhaes, Vitor; Makovsky, Yizhaq; Mata, Maria-Pilar; Max, Michael D.; Nielsen, Tove; Okay, Seda; Ostrovsky, Ilia; O'Neil, Nick; Pinheiro, Luis M.; Plaza-Faverola, Andreia; Rey, Daniel; Roy, Srikumar; Schwalenberg, Katrin; Senger, Kim; Vadakkepuliyambatta, Sunil; Vasilev, Atanas; Vázquez, Juan-Tomás (Journal article; Tidsskriftartikkel, 2019-08-16)
      Large national programs in the United States and several Asian countries have defined and characterised their marine methane hydrate occurrences in some detail, but European hydrate occurrence has received less attention. The European Union-funded project “Marine gas hydrate – an indigenous resource of natural gas for Europe” (MIGRATE) aimed to determine the European potential inventory of exploitable ...

    • Multiscale characterisation of chimneys/pipes: Fluid escape structures within sedimentary basins 

      Robinson, Adam H.; Callow, Ben; Böttner, Christoph; Yilo, Naima; Provenzano, Giuseppe; Falcon-Suarez, Ismael H; Marin-Moreno, Héctor; Lichtschlag, Anna; Bayrakci, Gaye; Gehrmann, Romina; Parkes, Lou; Roche, Ben; Saleem, Umer; Schramm, Bettina; Waage, Malin; Lavayssière, Aude; Li, Jianghui; Jedari-Eyvazi, Farid; Sahoo, Sourav; Deusner, Christian; Kossel, Elke; Minshull, Timothy A.; Berndt, Christian; Bull, Jonathan M.; Dean, Marcella; Chapman, Mark; Best, Angus I.; Bünz, Stefan; Chen, Baixin; Connelly, Douglas P.; Elger, Judith; Haeckel, Matthias; Henstock, Timothy J.; Karstens, Jens; Macdonald, Calum; Matter, Juerg M.; North, Laurence; Reinardy, Benedict (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-02-19)
      Evaluation of seismic reflection data has identified the presence of fluid escape structures cross-cutting overburden stratigraphy within sedimentary basins globally. Seismically-imaged chimneys/pipes are considered to be possible pathways for fluid flow, which may hydraulically connect deeper strata to the seabed. The properties of fluid migration pathways through the overburden must be constrained ...

    • Variability of Acoustically Evidenced Methane Bubble Emissions Offshore Western Svalbard 

      Veloso-Alarcon, Mario E.; Jansson, Pär; De Batist, Marc; Minshull, Timothy A.; Westbrook, Graham K.; Pälike, Heiko; Bünz, Stefan; Wright, Ian; Greinert, Jens (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-22)
      Large reservoirs of methane present in Arctic marine sediments are susceptible to rapid warming, promoting increasing methane emissions. Gas bubbles in the water column can be detected, and flow rates can be quantified using hydroacoustic survey methods, making it possible to monitor spatiotemporal variability. We present methane (CH<sub>4</sub>) bubble flow rates derived from hydroacoustic data ...

    • Variations in pockmark composition at the Vestnesa Ridge: Insights from marine controlled source electromagnetic and seismic data 

      Goswami, Bedanta K.; Weitemeyer, Karen A.; Bünz, Stefan; Minshull, Timothy A.; Westbrook, Graham K.; Ker, Stephan; Sinha, Martin C. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-02-10)
      The Vestnesa Ridge marks the northern boundary of a known submarine gas hydrate province in the west Svalbard margin. Several seafloor pockmarks at the eastern segment of the ridge are sites of active methane venting. Until recently, seismic reflection data were the main tool for imaging beneath the ridge. Coincident controlled source electromagnetic (CSEM), high‐resolution two‐dimensional (2‐D) ...
