Geochemical exploration of submarine seeps in Grønfjorden, Svalbard. RiS ID 10080

Submarine pockmarks are widespread features on continental margins and represent potential pathways for large quantities of a strong greenhouse gas, methane, escaping from subsurface sediments. Pockmarks in southern and northern Grønfjorden, Svalbard have been described previously by Forwick et al. (2009) and Roy et al. (2012). However, geochemical analyses of pore water and near surface sediments directly from seep locations are necessary in order to have a clear understanding of the nature and composition of fluids.
