Noble gas (He, Ne isotopes) and transient tracer (CFC-12, SF6) measurements from POLARSTERN cruise PS111 (Weddell Sea, 2018)
Noble gases (3He, 4He, 20Ne, 22Ne)The water samples for stable noble gas isotopes (3He, 4He, 20Ne, 22Ne) 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...
