    Physical oceanographic profiles of 43 CTD casts during MARIA S. MERIAN cruise MSM98 in 20201 in the North Sea (2023)

    Description: During the RV Maria S. Merian cruise 98, which took place between 08.01.2021 to 23.01.2021 bathymetry data based on multibeam echosounder (MBES) was recorded. The main objective of the cruise was focused on the hydrocarbon fluid emissions in the German North Sea and focused on the 'Entenschnabel'- area. In total, 43 CTDs were deployed, mainly to sample the methane content in the water column and to observe the stratigraphy of the water column. Oceanographic data as well as water samples have been collected at every CTD station. At the borehole locations of B11-2 and B18-1 but also at the DOK1-X Thor-1 and D1 well 4 CTDS per site have been deployed.Detailed information about the temperature, conductivity and oxygen of the water column have been carried out with a Seabird CTD/Rosette SBE911 with SBE-32 water sampler, equipped with 24 OTE bottles (10L).

    Gas hydrate structures and C1-C5 hydrocarbons at individual sites in the Gulf of Mexico (2010)
    PANGAEA
    In:  Supplement to: Klapp, Stephan A; Bohrmann, Gerhard; Kuhs, Werner F; Murshed, Mangir M; Pape, Thomas; Klein, Helmut; Techmer, Kirsten S; Heeschen, Katja U; Abegg, Friedrich (2010): Microstructures of structure I and II gas hydrates from the Gulf of Mexico.

    Description: Gas hydrate samples from various locations in the Gulf of Mexico (GOM) differ considerably in their microstructure. Distinct microstructure characteristics coincide with discrete crystallographic structures, gas compositions and calculated thermodynamic stabilities. The crystallographic structures were established by X-ray diffraction, using both conventional X-ray sources and high-energy synchrotron radiation. The microstructures were examined by cryo-stage Field-Emission Scanning Electron Microscopy (FE-SEM). Good sample preservation was warranted by the low ice fractions shown from quantitative phase analyses. Gas hydrate structure II samples from the Green Canyon in the northern GOM had methane concentrations of 70-80% and up to 30% of C2-C5 of measured hydrocarbons. Hydrocarbons in the crystallographic structure I hydrate from the Chapopote asphalt volcano in the southern GOM was comprised of more than 98% methane. Fairly different microstructures were identified for those different hydrates: Pores measuring 200-400 nm in diameter were present in structure I gas hydrate samples; no such pores but dense crystal surfaces instead were discovered in structure II gas hydrate. The stability of the hydrate samples is discussed regarding gas composition, crystallographic structure and microstructure. Electron microscopic observations showed evidence of gas hydrate and liquid oil co-occurrence on a micrometer scale. That demonstrates that oil has direct contact to gas hydrates when it diffuses through a hydrate matrix.
