The water samples were stored from the CTD/water bottle system without contact to atmospheric air and preventing air bubbles into gas tight copper tubes, which are clamped of at both sides. In the IUP Bremen noble gas lab the samples were pre-processed with a UHV (ultra high vacuum) gas extraction system. Sample gases are transferred via water vapour into a glass ampoule kept at liquid nitrogen temperature. For analysis of the noble gas isotopes the glass ampoules are connected to a fully automated UHV mass spectrometric system equipped with a two stage cryogenic system. Regularly, the system is calibrated with atmospheric air standards (reproducibility <0.2%). Also measurement of line blanks and linearity are done. The performance of the Bremen facility is described in Sültenfuß et al. (2009). In total, 49 noble gas samples were analyzed successfully. The total errors for the noble gas measurements are estimated to be 0.4% for 4He, 0.4% for total Ne, and 0.4% for δ 3He.According to the WOCE standards the following flags were applied to each measurement:
flag 2 = good
flag 3 = doubtful
flag 4 = bad
flag 6 = mean of replicates
flag 9 = no measurement (then, the data value is set to -9.000)-28.316312.440771.347878.9665North Greenland Sea
