NOC News Round Up - 5 May 2017

Could stored carbon leak through submarine chimneys?

Maria S. Merian

On Saturday the 29 April the German research vessel, Maria S. Merian, left Southampton for a research expedition to the Southern Viking Graben in the North Sea. The team on board will investigate the characteristics of sub-seafloor geological features known as chimney structures. Although these are common features, very little is known about their nature, in particular about their permeability for fluids. The science team, consisting of researchers from the NOC, GEOMAR, the University of Southampton and the University of Tromso will use state-of-the-art seismic techniques to investigate the characteristics of a selected chimney during the first leg. During the 2nd leg the British Geological Survey's sea floor drilling apparatus RockDrill2 will be used to sample the interior of the chimney directly, which will be analysed for core geology and fluid chemistry.

This expedition is the first cruise of the NOC-led STEMM-CCS project to find out more click here.


RRS Discovery returns to Southampton

The team on board

This week the RRS Discovery returned from the most recent expedition to the Porcupine Abyssal Plain sustained ocean observatory in the Northeast Atlantic. The expedition successfully recovered and redeployed the PAP moorings and a range of research relating to the biological carbon pump was undertaken. Near the end of the expedition a sea butterfly was caught (pictured below) using a zooplankton net. The 'Bathysnap' system for time-lapse photography of the seafloor was redeployed and continues to provide insights into deep-sea ecology.
