Ziel der Reise / Objectives of Cruise:
The two-week scientific cruise HE 537 on R/V Heincke was dedicated to investigate possible gas leakage from former drill sites in the German North Sea Sector. Recent studies have addressed methane seepage escaping near abandoned drill sites in the Central North Sea. These "shallow gas" releases with a possible anthropogenic component may be a relevant and so far unconsidered methane source and may contribute to ocean acidification and climate warming. Methane seepage has also been observed near former drill sites or at natural seep sites in the British and Dutch North Sea sectors. So far, it is still highly vague how relevant abandoned boreholes in the Central North Sea are in terms of gas seepage, and how much methane is naturally escaping from the seafloor.
